Use your Apple Watch to AUTOMATICALLY track your sleep!

The better you understand how well you are sleeping the more you are able to make changes in your routines to benefit your rest. Simply wear your Apple Watch overnight and each morning Sleep++ will analyze your sleep and give you a report about how long and restfully you slept.
