* There's is a lengthy discussion about which melacha is involved when using electricity. One suggestion is that it is a violation of [[Mavir]] ([[Lighting a fire]]). See a very interesting comparison of Rav Henkin (Edut LeYisrael p. 151) who seems to compare an electric current to movement of electrons when a person starts to walk or hits a piece of metal and says that’s not called a fire unless the fire is visible. Rabbi Yitzchak Schmelkes Beit Yitzchak Hashmatot to YD 2:31, says that completing a circuit constitutes a rabbinic violation of [[molid]]. In Beitza 23a the gemara prohibits one from adding scent to a garment because of [[molid]]. Similarly, the Beit Yitzchak argues, introducing electricity into a device is [[molid]].
* Rav Shlomo Zalman Auerbach Minchat Shlomo 1:9 says that the two are different because adding a scent to a garment is adding something to it, that it never had before. Electricity on the other hand was put into this device to be activated and deactivated often. Rav Shlomo Zalman concludes that even without light, the halachic precedent has been established to be concerned for a rabbinic prohibition with the activation of electric device. The Chazon Ish OC 50:9, rules that completing a circuit constitutes a violation of the melacha of boneh, building and deactivating a device by opening the circuit would constitute a violation of [[soter]], destroying. Another possibility raised by Heichal Yitzchak 43 is the prohibition of makeh bepatish, delivering the final blow, completing any item in a way that now renders it beneficial. </ref>
# According to many poskim it is Biblically forbidden to turn on an incandescent and fluorescent light bulb. However, if one needs to turn on a light for someone who is mortally sick (see [[Medicine on Shabbat]]) one should turn on a fluorescent instead of an incandescent light bulb. <ref>Menuchat Ahava 24:3-4. Incandescent bulbs and halogen bulbs contain filaments that can get extremely hot. The Gemara [[Shabbat]] 42a, discusses the concept of gachelet shel matechet, a glowing hot piece of metal. The Avnei Nezer OC 229 based on the gemara in [[shabbat]] 42a says that according to most Rishonim, heating a piece of metal to the point that it is glowing hot is a biblical violation of havarah, kindling. Rav Shlomo Zalman Auerbach in Minchat Shlomo 1:12, says that since turning on an incandescent bulb ignites a glowing hot metal filament, it would be in violation of havarah from the torah. </ref>
==Using Electric Appliances==
# According to many poskim it is Biblically forbidden to turn on an oven or warming plate. <ref>Menuchat Ahava 24:3 </ref>
# It is forbidden to turn off or dim an electric light. <ref> While Melamed Lehoil OC 49, Kuntres Gorem HaMalot 185, Maharsham 2:146, Minchat Shlomo pages 85-88 and pages 107-109, Shemirat [[Shabbat]] Kehilchatah 13:1 all say this prohibition is rabbinic and this is the conclusion by [http://www.daat.ac.il/DAAT/english/journal/broyde_1.htm Rabbi Jachter and Rabbi Broyde], Machaze Avarham OC 41 and Beit Yitzchak Hashmatot YD 2:31:8 say it is a violation from the torah and this possibility is also raised by Rav Shlomo Zalman. </ref>
# It is forbidden to turn off any electric appliance. <ref>Menuchat Ahava 24:5 </ref>
# It is forbidden to pick up a phone off the receiver, speak on a phone, or return the phone to the receiver on [[Shabbat]]. <ref> Menuchat Ahava 24:6,8,9.
* Lifting the PhoneIn addition to the problems of circuits or the problem of a light flashing when lifting the phone, Rabbi Levi Yitzchak Halperin in Maaseh Choshev 1:60 argues that starting the dial tone violates the rabbinic prohibition of making a noise, or hashma'at kol. *DialingIn addition to the problem of circuits being built by dialing a phone, Rabbi Benzion Meir Chai Uziel Mishpatei Uziel 1:13 writes one violates makeh bipatish, delivering the final blow but Chacham Ovadia Yosef in Sh"t Yabia Omer 1:20 disagrees because the phone is a functional object even before one dials. Rabbi Yitzchak Schmelkes Beit Yitzchak Hashmatot YD 2:31 and Rabbi Chaim Ozer Grodzinski Achiezer 4:6 say that one violates the rabbinic prohibition of making a noise, hashmaat kol, in the place where the phone rings. Rav Shlomo Zalman Auerbach Minchat Shlomo pages 75 and 76 argues that maybe since this is indirect and rabbinic one may be lenient. In the Sinai 5705 journal page 152 he argues that since the noise is made in another's house it is possible that the rabbinic prohibition doesn't apply at all because you would never come to fix the object in someone else's house.*Talking into the PhoneRabbi Yitzchak Schmelkes Beit Yitzchak Hashmatot YD 2:31 asserts that talking into the phone is also a problem of making a noise, or hashmaat kol. [[Rabbi Shlomo Zalman Auerbach]] Minchat Shlomo page 67 and Rabbi Eliezer Waldenberg Tzitz Eliezer 1:20:10 both disagree based on the Rama 338:1 where he rules that the prohibition of making a noise doesn't apply when this is done through a human voice. Since talking into the phone increases the electrical current being used, Rabbi Yitzchak Yaakov Weiss Minchat Yitzchak 3:38 and 3:60 prohibits based on that. Rav Shlomo Zalman Auerbach (Minchat Shlomo page 110) writes that the increase in current is not a problem in appliances where heat is not created.</ref>
# Some say it is a good practice to unplug the phone before [[Shabbat]] so that if someone calls on [[Shabbat]] one won't hear it ring. <ref>Menuchat Ahava 24:10 </ref>
# It is forbidden to speak into a tape recorder even if the recorder was turned on before [[Shabbat]]. <ref>Menuchat Ahava 24:13, Yechave Da'at 2.
57 </ref># It is permitted to use an electric blanket on [[shabbat]], provided one does not move the knob that adjusts it. It is proper to place scotch tape on top of the knob in order to prevent oneself from accidentally adjusting the blanket on [[shabbat]]. <ref> Igrot Moshe 3 .50, Menuchat Ahava 1 .24 .37, Yechave Da'at 2 .49 </ref>
===Automatic Doors, Doorbells, and Door Chimes===
# It is forbidden to enter an automatic electric door which opens with a motion sensor unless there is a need to enter a hospital with an electric door for the needs of a patient who is in a life threatening situation. <ref>Shemirat Shabbat Khilchata 40:19</ref>
# It is forbidden to press an electric doorbell on [[Shabbat]]. <ref>Menuchat Ahava 24:14 </ref>
# Some say that it is forbidden to open a door that will cause an electric chime or bell to go off.<ref>Chelkat Yakov 1:78 writes that it is forbidden to enter a door that will cause an electric chime to go off. He explains that even though it is a Shinuy, Melacha Sheino Tzaricha Lgufa, and a Pesik Reisha Dlo Nicha Leh since the concern is a Biblical one of Maavir it is prohibited. He was discussing a device that created sparks when the circuit was closed and he considered those to be a Biblical violation of Shabbat. He also points out that perhaps this isn't considered a Shinuy since that is how the system is set up to be used. However, regarding Yom Tov he is lenient since Molid Esh is only derabbanan. Shemirat Shabbat Khilchata 23:57 agrees that it is forbidden to enter a door with an electric chime or bell.</ref>
* Lastly, Chelkat Yaakov O”C 76 argues that while it may be a psik reisha, perhaps it is not considered grama since this is the intended normal way it is used. Therefore, he rules that one may only open the door when the motor already is running. Minchat Yitzchak 2:16 and 3:24, Az Nidberu 2:36, Sh"t Igrot Moshe 2:68, 4:74, and Mishnat Rabbi Aharon 1:4 agree.
* Shemirat [[Shabbat]] KeHilchata 10:12, Orchot [[Shabbat]] (vol 3 p. 62), and The [[Shabbos]] Home (p. 482) quote the two approaches but do not give a final ruling. Shemirat [[Shabbat]] Kehilchata (10:12) recommends setting the refrigerator to a timer.
* [http://www.yutorah.org/lectures/lecture.cfm/742318/Rabbi_Mordechai_I_Willig/Halacha_Engages_Modernity_-_Part_8_-_Electrical_Appliances_(Part_1) Rabbi Willig (min 33-35)] says that using a water fountain on [[Shabbat]] depends on how long it takes for the motor to turn on. He mentions that one shouldn't use a water fountain which clearly will have the motor go on with a single regular use. However, he did not say this as a definitive ruling but in passing.* See [http://www.zomet.org.il/Eng/?CategoryID=253&ArticleID=143 Zomet.org] or [http://www.star-k.org/kashrus/kk-cooling-keepcool.htm star-k.org] for details on other problems with refrigerators. </ref> If one forgot to disable the light he is permitted to ask a gentile to open or close the refrigerator for him. <ref> Yalkut Yosef Chelek 4 [[Shabbat]] 5 page 229, Iggerot Moshe OC 2:68, and Shemirat [[Shabbat]] Kehilchatah 3:31. The aforementioned poskim all reject the opinion of the Aruch either because psik reishe dilo nicha leih is not permitted and they also argue that it is nicha leih because had it not been [[shabbat]] one would certainly want the light to help him see (see minchat shlomo page 91), and say that one should get a gentile to do it for him. [http://www.daat.ac.il/DAAT/english/journal/broyde_1.htm Rabbi Broyde and Rabbi Jachter] permit even asking a Jew who doesn't know that the light will turn on as this would fall under the category of mitasek. Iggerot Moshe OC 2:68 and Shemirat [[Shabbat]] Kehilchitah 31:1 also permit hinting to the gentile to disable the light so that the refrigerator could be used for the remainder of [[shabbat]], but not telling him directly. </ref>
# Many poskim permit walking in an area where there surveillance cameras will capture a person’s image as long as he does not intend to be recorded. <Ref>
* Rabbi Hershel Schachter ([http://www.yutorah.org/lectures/lecture.cfm/764993/Rabbi_Hershel_Schachter/Electricity_on_Shabbos “Electricity on Shabbos,”] min 62-8) explains that if one is doing an action that is physically disconnected from where the melacha is occurring, it isn’t considered a psik reisha. Thus, Rav Schachter says that there’s what to rely on to permit walking in an area where there is a surveillance camera or a motion sensor which will turn on a light as long as one doesn’t have intent to be videoed or turn on the light.
* Sh"t Besel Chachma 6:65 suggests that walking in a place where there are surveillance cameras isn't considered Koteiv whatsoever and is no different than looking in a mirror on [[Shabbat]].</ref>
===Motion Sensor Toilets===
# Many poskim permit using an electrical automatic toilet if no other toilet is available. <Ref>
* Practical Laws of [[Shabbat]] (Rabbi Rafael Soae, p. 335) quotes Kedushat HaShabbat (Rabbi Moshe Harari p. 79) who says that if there’s no other bathroom available other than one which has toilets that automatically flush when one moves away, one may use the toilet because of Kavod HaBriyot.
* Rabbi Yisrael Belsky in Shulchan HaLevi 7:7 permits using this type of bathroom if there is no other bathroom available, but if there’s another option, he forbids using the electrical toilet. Rabbi Aryeh Lebowitz ([http://www.yutorah.org/lectures/lecture.cfm/761805/Rabbi_Aryeh_Lebowitz/Ten_Minute_Halacha_-_Using_Automatic_Bathrooms_on_Shabbos “Using Automatic Bathrooms on Shabbos”]) quotes Rav Belsky as saying that kavod habriyot would not be a leniency in order to wash one’s hands with an automatic sink. </ref>
# If someone has a grama system (for example [http://www.zomet.org.il/eng/?CategoryID=251&ArticleID=115 Zomet's grama alarm]) set up so that when the door is closed a mechanism will close an alarm system after some time, according to some poskim it is permitted to use it for a significant need.<ref>Minchat Shlomo 2:60:20</ref>
===Motion Sensor Lights===
# Some poskim permit walking in an area where a motion sensor will turn on a light provided that one does not intend to turn on the light if there’s no other way to walk. <Ref>
* Sheivet HaLevi 9:69 permits walking in an area where there is a motion sensor that will activate a light, such as those attached to the outside of buildings. He explains that davar she’eino mitkaven refers only to when one does an action that may cause an unintended melacha. If, however, one is walking normally and makes no motion in order for a melacha to occur, it is not even a psik reisha as long as one’s intent isn’t to turn on the light. Orchot [[Shabbat]] (p. 79) quotes Rav Elyashiv and Rav Nissim Karlitz who say that since one doesn’t have a direct connection to the melacha and doesn’t care about the light, it’s not called melechet machshevet. The [[Shabbos]] Home (p. 489) agrees.
* Rabbi Mordechai Willig ([http://www.yutorah.org/lectures/lecture.cfm/742317/Rabbi_Mordechai_I_Willig/Halacha_Engages_Modernity_-_Part_8_-_Electrical_Appliances_(Part_1) “Halacha Engages Modernity Part 8,”] min 50-60) challenges this line of reasoning because it should be considered a psik reisha d’nicha lei and turning on a light might be deoraitta. Furthermore, The 39 Melachos (p. 1215) says that if one can’t avoid walking in a place that will turn on a light because of a motion sensor and the streets are dark so that one will benefit from the light turning on, one shouldn’t leave his house! He does permit one to walk past such a motion sensor if he closes his eyes at the time when the light will turn on because in such a case then it is not considered niche lei, even if one will open one's eyes right afterwards.
* On the other hand, Rabbi Hershel Schachter ([http://www.yutorah.org/lectures/lecture.cfm/764993/Rabbi_Hershel_Schachter/Electricity_on_Shabbos “Electricity on Shabbos,”] min 62-8) explains that if one is doing an action that is physically disconnected from where the melacha is occurring, it isn’t considered a psik reisha. Thus, Rav Schachter says that there’s what to rely on to permit walking in an area where there is a surveillance camera or a motion sensor which will turn on a light as long as one doesn’t have intent to be videoed or turn on the light. </ref>
# If one is already in the room that has a motion sensor and the lights are on and as long as one is inside the lights stay on one may stay in the room.<ref>Minchat Asher 1:31:5</ref>
===Hearing Aids and Microphones===
# Someone who's hard of hearing may use a hearing aid which was turned on before [[Shabbat]]. It's proper to attached a piece of scotch tape on the button so one doesn't come to turn it off on [[Shabbat]]. <ref>Menuchat Ahava 24:11, Sh"t Yabia Omer 1:19(19), Minchat Yitzchak 2:17-8, 3:41, Minchat Shlomo 1:9, Tzitz Eliezer 6:6, Shemirat [[Shabbat]] Kihilchita 34:28</ref>
# It is permitted to use a hearing aid on Shabbat even if it automatically adjusts the volume depending on the loudness of the environment.<ref>Rav Asher Weiss in Minchat Asher 1:31:1 writes that using hearing aids which automatically adjust depending on your surrounding. In a quiet place it amplifies noise and in a loud place it lowers the amplification. He explains that it is permitted to use them and move around while wearing them since either that isn't considered your action that the device changed its functionality or that it is but it is permitted since the accomplishments of the change in voltage in the circuit are insignificant and don't violate makeh bpatish, boneh, or molid. The automatic mode of hearing aids is described here: https://www.boystownhospital.org/knowledgeCenter/articles/hearing/Pages/PutYourHearingAidsOnAutomatic.aspx.</ref>
# It is forbidden to use a microphone on Shabbat.<Ref>Rav Shlomo Zalman Auerbach 1:9 s.v. ach writes that even if one solves all melacha issues with speaking into a microphone on Shabbat nonetheless it is forbidden since it creates an audible noise which is a violation of Avsha Milta (Shabbat 18a, Rama 252:5), which is Zilzul Shabbat. One of his precedents is the Nodeh Byehuda OC 30 regarding umbrellas where there is a concern of Zilzul Shabbat even if it was open before Shabbat.</ref>
# A patient hooked up to a monitor that measures his heartbeat and the like doesn't have to be concerned for its functioning on Shabbat.<ref>Minchat Asher 1:31:2</ref>
# It is forbidden to set a timer before [[shabbat]] to automatically operate a dishwasher on [[shabbat]]. <ref> Shemirat Shabbat Kehilchata 12:37, Menuchat Ahava 1.24.31. The Shemirat Shabbat Kehilchata's proof is that when you close the door even though it is totally off it is considered a grama when the melacha will occur later like we find in Mishna Brurah 253:100. [http://www.yutorah.org/sidebar/lecture.cfm/859947/rabbi-hershel-schachter/status-and-applications-of-use-of-electric-appliances-and-devices-on-shabbat/ Rav Hershel Schachter (Electricity on Shabbat min 35)] explained that it was forbidden to use a dishwasher on Shabbat even if it is going to turn on at a later time since closing the door is considered a grama for when the timer will turn on.
Since the dishwasher doesn't function if it isn't closed it may not be used. It is also forbidden to illegally get a mechanic who will break the dishwasher so that it starts even if the door isn't closed.</ref>
==Setting Timers before Shabbat==
# One may set an alarm clock before [[Shabbat]] even though it will make noise on [[Shabbat]]. <ref>The [[Shabbos]] Home (Rabbi Simcha Cohen, vol 2, pg 537) and Sh"t Maharshag YD 1:7(2) permit. However, Sh"t Igrot Moshe 4:70(4) only permits if it is not heard outside his personal room. See Shemirat [[Shabbat]] KeHilchata 28:29 (and 28:30 in new edition) who permits before [[Shabbat]] for mitzvah purposes setting a mechanical alarm clock that involves removing a pin (see there). </ref> See [[Making music on Shabbat]].
# Some forbid leaving a digital photo frame which presents a slideshow of pictures set from before [[Shabbat]] to continue during [[Shabbat]]. <ref>[http://www.ou.org/webcast_kosher Rav Hershel Schachter] (OU Kosher Webcast, 2011, min 16-8) </ref>
==Sending Email on Friday==
* Rav Ovadyah Yosef (Yalkut Yosef [[Shabbat]] vol 1 pg 188, Yabia Omer OC 2:17) agrees that one can make a bracha on it but emphasizes that it's a last option and that preferably one should have a designation that the bulb is for [[Shabbat]] candles.
* Rav Shlomo Zalman (Shemirat Shabbat Kehilchata (ch. 43 fnt. 22) held that using an electric bulb plugged into the wall is questionable since the fuel to keep it lit on Shabbat wasn't present at the time of the lighting. Rav Moshe Feinstein (quoted by Rabbi Tendler in Moreshet Moshe v. 2 p. 51) agreed with this concern.</ref> This is because the light bulbs essentially accomplish the role<ref>Tosfot [[Shabbat]] 25b</ref> that the traditional [[Shabbat]] candles are intended to serve.<ref>There are two reasons why we light [[Shabbat]] candles. The first is for “Oneg [[Shabbat]]” which requires that the home be illuminated Friday night in order that people not stumble in the dark. The second reason is for “Kavod [[Shabbat]]” which calls for plentiful lighting in honor of [[Shabbat]], as was the custom upon receiving a distinguished guest. </ref> The electric lights actually become the [[Shabbat]] candles and one will discharge one's [[Shabbat]] candle lighting obligations with them. While such an approach should never be relied upon in normal circumstances, it is permissible in extenuating ones. Some authorities suggest that when making use of electric lights for one's [[Shabbat]] candles the accompanying blessing should be omitted.<ref>Shraga Hameir 5:11. see also The Radiance of [[Shabbos]] (p. 12) who quotes Rav Moshe Feinstein as saying that one should not recite a bracha on an electric light. </ref>
# If one is forced to use the electric lights in one's home as the [[Shabbat]] candles they should be shut off momentarily and then turned back on in order for them to now be designated as the [[Shabbat]] "candles".<ref>Teshuvot V’hanhagot 2:157</ref> Indeed, every week before the lady of the house lights her [[Shabbat]] candles, she should momentarily turn off the household lights and then turn on them back on. When she makes her blessing over the candles she should have in mind that her blessing include the electric lights as well which will also be providing light over the course of [[Shabbat]].<ref>Az Nidberu 1:79, Shemirat [[Shabbat]] Kehilchata 43:N171 </ref> Those who are forced to use the electric lights instead of candles should endeavor to turn on even those lights which are not normally used in order for there to be some distinction that the electric lights are in honor of [[Shabbat]].<ref>Tzitz Eliezer 1:20</ref> Even a desktop light could be used for this purpose. Some say that this only includes incandescent bulbs and not fluorescent.<Ref>Rav Hershel Schachter (“Lighting [[Shabbos]] Candles,” min 36-7) holds that while one may light an incandescent bulb with a bracha, one may not light a fluorescent or neon bulb with a bracha. This opinion is repeated in [http://www.yutorah.org/lectures/lecture.cfm/839951/Rabbi_Hershel_Schachter/Jewish_Heritage_Tour_of_Hungary_Part_10_of_10 this shiur on yutorah.org].</ref>
# The issues are essentially the same with regards to [[Havdala]] and one may use an electric light in place of a [[Havdala]] candle in a time of need.<ref>Shaarim Metzuyanim Behalachah 96:6, Az Nidberu 8:2, Rivevot Ephraim 3:599</ref> In fact, it is reported that Rabbi Chaim Ozer Grodzinsky would always use an electric bulb for [[Havdala]] in order to demonstrate how strongly he felt that electricity is to be treated exactly like fire from the perspective of halacha.<ref>Shaarim Metzuyanim Behalachah 96:6. Nefesh Harav pg. 156</ref> Nevertheless, there are those authorities who discourage the use of an electric light for [[Havdala]]. Among their opposition to it is the fact that the blessing recited upon the [[Havdala]] candle includes the word "fire" which seems to imply the need for actual fire, not merely light. As such a light bulb would not be acceptable according to this view.<ref>Har Tzvi 2:114</ref> Even among the authorities who permit the use of electric lighting when needed many would disqualify the use of fluorescent bulbs as they work differently than standard light bulbs.<ref>Hachashmal L’or Hahalacha 3:88 </ref>
# Screen: Turning the screen on and off is similar to turning a regular light on and off - this can be an issur derabanon of making a fire (Mavir) according to some Poiskim. <ref>See Rabbi Shmuel Eliyahu in [http://www.yutorah.org/lectures/lecture.cfm/803195/Rabbi_Shmuel_Eliyahu/%D7%93%D7%99%D7%95%D7%9F_%D7%94%D7%94%D7%9C%D7%9B%D7%AA%D7%99_%D7%A2%D7%9C_%D7%A9%D7%99%D7%9E%D7%95%D7%A9_%D7%91%D7%98%D7%90%D7%91%D7%9C%D7%98_%D7%9C%D7%90%D7%A0%D7%A9%D7%99_%D7%A2%D7%96%D7%A8%D7%94_%D7%A8%D7%90%D7%A9%D7%95%D7%A0%D7%94_%D7%91%D7%A9%D7%91%D7%AA a shiur on yutorah.org] about using tablets on Shabbat for the Magen Dovid Adom and doctors in hospitals.

==The Shabbos App==
* ''Eino Kayama'': Having the data erased hourly is not a reason to permit writing on smartphone. 1) Writing in a non-permanent fashion is still asur m'derabbanan.<ref>Mishna (Shabbat 104b), Rambam (Shabbat 11:15), Shulchan Aruch 340:4</ref> 2) It is not temporary - anything which lasts as long as you need it to last even if it is erased afterwards isn't temporary.<ref>Rav Hershel Schachter ([http://www.yutorah.org/lectures/lecture.cfm/799655/Rabbi_Hershel_Schachter/Shiur_#28_-_Shabbos_-_Boneh,_Koseiv Gemara Shabbat Shiur #28 (min 32-3)]) explained that every writing in the world is temporary. Rather the Mishna considers anything that doesn't last as long as a person would normally need it for to be temporary. However, a camera system which is deleted after some time is considered permanent since it serves the intended purpose by being recorded and kept for as long as it is was necessary. He added that this is reasonable since this is how the industry makes such camera's and doesn't consider the recording to be flawed in that it doesn't last forever.</ref> 3) The quality of the writing is permanent. Even though when you write it you know that you'll erase it soon or you set up a system which will erase it soon, the writing in it of itself is permanent if not erased afterwards.<ref>Avnei Nezer OC 180</ref>
* ''Zilzul Shabbat'': The Gemara Sanhedrin 46a describes a case in which the supreme court in Yerushalayim condemned a person who rode a horse on Shabbat. Even though technically, riding a horse on Shabbat is only a rabbinic prohibition, it is considered a serious infraction upon the sanctity of Shabbat.<ref>Rambam (Sanhedrin 24:4) codifies this.</ref> According to Rav Moshe and many gedolim this would be considered zilzul Shabbat.<ref>Igrot Moshe OC 4:60
</ref> The burden of proof is upon the one trying to deviate from the standard practice to show that this isn't zilzul. <ref>Mishna (Bava Kama 76a)</ref> * Bottom line - a person should not use this app on Shabbat.<ref>[http://www.thejewishweek.com/news/international/new-shabbos-app-creates-uproar-orthodox-circles The Jewish Week] cites Rabbi Moshe Elefant (from the OU) as considering the Shabbos App to be "very distasteful and not permissible on Shabbos.” [http://www.yutorah.org/lectures/lecture.cfm/818766/Rabbi_Michael_Siev/Five_Minute_Halacha_-_The_Shabbos_App# Rabbi Michael Siev] from Yeshivat Lev HaTorah explained how that the App is halachically problematic. Besides the issues above, he adds that the display changing is an issue. </ref> If someone wants to become non-Orthodox (and keep half-shabbos) they're don't need to ask anyone's permission or pervert halacha to do so, but please don't pretend that this is actually Orthodox. <ref>Rav Hershel Schachter (shiur on yutorah 10/3/14) merely mentioned the Shabbos App as a "chiddush" of our generation in a joking manner. He didn't go into any detail as he explained the he didn't know of its details.</ref>
