Get FREE access to premium features until 2023! Experience the revolutionary gentle alarm and sleep tracker that senses your movements with "silent sonar" technology.

Wake up fresh with the revolutionary motion-sensing sleep tracker, smart alarm and relaxation app.

Sleepwave accurately detects motion using your phone’s microphone and speakers by listening to the reflections of a silent soundwave.

The app uses its technology to power accurate sleep tracking, an improved waking experience, and new ways to relax and unwind.

• Wake up feeling more energized with Sleepwave’s motion-sensing smart alarm. Set a time window around when you need to wake up and the smart alarm will sound when you’re naturally awakening.

• Sleepwave transforms your phone into a contactless sleep tracker. The app breaks down your sleep into stages so you can get insights into your night. With detailed, easy-to-understand charts and graphs, you can understand your sleep patterns and habits over time. You can also log your daily activities to see their influences.

• Wavescapes are interactive visualizations that respond to your movements without having to touch your phone. Choose and play with different patterns to help refresh or focus your mind.

• Why should a wake up be alarming? Choose from original alarm sounds composed by renowned musicians, or gently rise with a series of "soft awakening" soundscapes that start before the main alarm. At night, you can fall asleep to a collection of sounds from the natural world.

• Fall asleep or wake up to your favorite music or select from playlists specifically designed for sleep.
• Write your sleep data to Apple Health.

• No login is required to use the app. We don’t collect your personal details. Sleepwave uses your phone’s microphone to detect movement but no audio data leaves your phone. All the sleep analysis happens on your device with no internet connection required.

• Everybody’s sleep is different. If you stay out late with your friends, Sleepwave won’t judge you with a bad sleep score. Instead, the app empowers you to understand your sleep and set your own goals.

• Smart alarm and sleep tracking are free for everyone. Some additional features are accessed with a great value annual subscription.

• Detailed breakdown of sleep stages showing light, deep and REM sleep
• Weekly, monthly and yearly sleep patterns
• More Wavescapes to help you focus, relax and play

Seriously helpful

As someone who is used to snoozing a handful of times every morning, I wasn’t prepared for a free app to truly change the way my days start. Before downloading this app, I was awoken by loud alarms and would delay the start of my day by 30 minutes usually. Now, I wake up gently and usually feeling pretty refreshed. The technology works and I’m so glad that this app is free, allowing more people to experience it. I also love the option to play rain noise as you’re getting ready to fall asleep. Can’t wait to see what other features are added as time goes on.

Super unique! Amazing technology!

I fell in love with this app! It has many unique features such as the smart alarm where you can choose to wake up gently from a duration of 15 minutes or more! However, one of my favorite parts of the app was the Wavescapes which is found in the “Relax” tab. I felt as though it really did relax me and the Wavescapes were so mesmerizing to watch! I highly recommend this app to anyone who wants to track their sleep patterns but also wants help getting to sleep and waking up gently instead of using your standard and abrupt alarms.

So Far It’s Amazing!

Using for over a week and It knows exactly when to wake up up so you don’t feel groggy! I was slugging though my days and now I much more alert for my 6:30am Scrum call, which as a night owl is a game changer!

One recommendation- I would love for the nighttime music to have binaural beats options or something for the whole night for noisy bar going neighbors coming home at 3am. the white noise for a few min is fine, but sometimes a sound based sleep aid would be helpful!
