I've put a lot of thought into that. If you take a look at the app - it's free for now - you can see that it's easy to use without bothering others in the theater. The Timer feature is the most obvious method of using the app unobtrusively, but there are also other ways, like simply memorizing the time/cue for the Peetime of choice and looking for it during a film. We try our best to make the "cues" as memorable as possible.
That being said, there's nothing I can do to prevent, how to put this, less than considerate people from abusing the app.
