The idea is great, but it doesn't help me with my goals. The thing is: i have to use it on silent and facedown, so others notifications (and lights) don't bother me. Here lies the problem: when the time runs out, the app doesn't vibrate... Cause of that i have to constantly check the hour, which is not good at all for me. I'm using a galaxy s7. Edit- See, that's the prob. I did everything in the answer, except turn off the silent mode... As i said, there's no use for me if i have to do that! Tks anyway.
