DY: Honestly, I think the whole thing is a joke. No one’s actually making this app.
And they’d be at Shul, with their phone dead by the time they got home. 😛
Look, it’s clear there’s not a Muttar way to set up a smartphone to use on Shabbos. But plenty of inventions have entirely overhauled how Shabbos is celebrated. Electric lights, air conditioners, timers, Shabbos elevators, escalators/moving sidewalks, wheelchairs, board games, and more. So if this would also change it in an entirely Muttar way, there’s nothing inherently wrong with it.
