Because speaker and microphone setups vary from one phone model to the next, our team verifies each device to ensure the most accurate sleep tracking. The Sleep.com app supports the following devices, each of which has been fully verified: iOS: iOS software 11.2 and above  iPhone 6 and 6 Plus  iPhone 6S and 6S Plus  iPhone 7 and 7 Plus  iPhone 8 and 8 Plus  iPhone X  iPhone XS  iPhone XS Max  iPhone XR  Android: Android software 6 and above  Samsung Galaxy S7 Edge and S7  Samsung Galaxy S8 and S8+  Samsung Galaxy S9 and S9+  Samsung Galaxy Note 8 and 9  Google Pixel 2 XL   For the optimal app experience, we recommend using a fully supported device. If you use the Sleep.com app with an unsupported model, you’ll still be able to track your sleep but could experience some disabled features. We’re working diligently to expand our list of supported devices, so please check back regularly if you don’t see your phone included above — and consider joining our Android Early Access Program to help us validate your Android model faster.
