If you haven't heard about The Shabbos App yet, it's meant to modify the function of your smartphone to avert halachic problems involved in texting on Shabbat.
Here is the opening line of their "Who we are" paragraph:
We are a team of people including programmers, marketing professionals and Rabbis who want to make it easier to be Jewish and fully observant. Today, there are too many people leaving the fold because they find observant Judaism too cumbersome and outdated and it doesn't need to be.
It would be fun to discuss the ins-and-outs of their mechanisms, which are briefly described (sans important halachic details) on their website. Indeed, Rabbi Yisrael Rozen of Machon Tzomet has pointed out a gaping hole in their understanding of grama, here. But I am more interested in their premise: that people are leaving Judaism because halachah is cumbersome and outdated, as demonstrated by the inability to use a cell phone on Shabbos.
I can see ways in which the halachic system is lagging in dealing with new realities, but to me, turning off a cell phone for Shabbos does not demonstrate an outdated halachic system. Just the opposite, it demonstrates the need for the classic halachic system of Shabbos!
I think the Shabbos App is a terrible idea. Am I really the only Jew who was relieved to not answer a phone call or an email for three consecutive days on Rosh HaShanah and Shabbos? For me, if such a break did not exist, I would have to invent it - just as psychologists routinely recommend to their patients that they take time out from the demands of the world on a regular basis.
It's also important to walk away from the phone for a whole host of other reasons, beyond the scope of this post; take Louis CK's advice and turn off the phone!
So I find the "Shabbos App" idea most un-app-ealing. It's not what I want for myself, for my children, or for my environment. I shudder to think of spending Yom Kippur in shul, Succos lunch with friends, Simchas Torah dancing with the Torah or Shabbos afternoon at the park surrounded by texters. Please, please: lay off my Shabbos!
