App works very well and great tracking features. The wake up feature is awesome and helps to wake up at the optimal time and feel more refreshed, BUT I hate that I cannot disable the alarm from my watch! It just buzzes CONSTANTLY with no snooze or stop function. I get that this is supposed to force me to get up, get out of bed, go grab my phone, and stop it that way... Problem is, I don't like being forced to do anything and should be able to stop the alarm from watch. I think I'm done.

This used to be a great app. Then it introduced automatic snooze, which was annoying but tolerable: it meant that when you pick up your phone to turn off the alarm, it snoozes before you can shut it off for good. Now the app has abandoned the accelerometer in favor of the microphone, which is bad for privacy. CORRECTION: There's a setting to use the accelerometer, they just don't tell you there's an alternative when they demand mic access. Go to Profile > More > Motion detection.

You can change your snooze preferences in settings. Go to Profile>Settings>More>Alarm>Snooze . At this point, simply pick a regular snooze or turn it off. You can also choose between the accelerometer and microphone setting as you mentioned. If you have further questions, please don't hesitate to email:

I love this app, it's so fun to get to hear my sleep talk recordings and this app helps motivate me to get better sleep! I've shared it with so many friends! Two features I'd love to see would be (1) being able to delete all the sound recordings from a day with one or two clicks instead of having to delete each one separately, and (2) being able to delete all of one type of recording at once (I always delete my snoring but save sleeptalk). Thanks for making this awesome app!
