Ive always had a problem with hitting snooze and getting up on time. It affected my partner because Im a heavy sleeper while they are a much lighter one. This alarm has basically conditioned me to hop out of bed immediately to go turn off the alarm.
Ive only had two (preventable) negative experiences with the app. First, my phone ran out of battery right when the alarm started, so when the phone was recharged enough to turn on automatically, the alarm would trigger and the phone would die again. I eventually was able to turn off the alarm quickly enough to not turn off the phone again. The other experience was when I had the alarm go off when I wasnt home so the photo option wouldnt work. After a few phone restarts, the app defaulted my alarm turn-off method to shaking instead of taking a picture. I dont know if thats a feature or not, but it worked for me (on a previous version of the app). So just remember to have enough charge before the alarm goes off and to always keep the alarm off until you really need it and you should have a positive experience overall.
