Thanks for the fedback Seferi, I think it’s way too early to think about monetizing (it will probably never have enough users to make it worth the hassle of setting up payments and stuff).
About intervals: I decided to go with a very complicated logic that tries to check more often when the phone is plugged in and less when it’s on battery. When it’s on battery it will also try to “batch” the polling along with other apps so that it never wakes up your phone just to check if it’s your turn, thus saving battery. Hence that setting will probably do more bad than good.
So far on my phone it works so well that it doesn’t even register on the apps that eat up battery. I’m curious if it’s the same for you guys (you can see which apps eat your battery in settings -> battery).
Out if curiosity, if you would have the option, would you set it to poll more often or more rarely than it does right now?
