Sleepwave is a free lifestyle app that works as a smart alarm clock and sleep tracker for Android devices. It features motion-sensing technology that accurately tracks your sleep and wakes you up with gentle alarm sounds at the perfect moment for your body.

With Sleepwave, you can choose from a collection of original alarm sounds or wake up with a “gentle awakening” soundscape that plays before the main alarm. The app also offers an analysis of your sleep, which is easy to understand, and colorful patterns or water ripples to help refresh or focus your mind.

Sleepwave respects your privacy and does not require any login or collect personal details. The app uses your phone’s microphone to detect movement, but no audio data leaves your phone. Sleepwave’s free tier offers all the features in the app for three nights per week without any purchase or commitment.

The app has received positive reviews on the Google Play Store, with users appreciating the informative sleep analysis and the app's effectiveness in helping them sleep better.

If you're looking for a reliable and free sleep tracker and alarm clock that respects your privacy, Sleepwave may be an excellent choice for you.
