Bacu Sleep

Learn how much sleep you need for your age and how many hours you are getting. Also, you can be reminded when you should go to bed, making it easier to achieve your goal. This integrates with the Apple Health on your iPhone.

Track Your Sleep.
Use any sleep tracker you own (e. g. Apple Watch), or let the app track your sleep by using your iPhone's motion and fitness data. 

Adjust Target.
Select your hours of sleep from a recommended range of hours you should get according to your age, and see and adjust your bedtime and wake up time.

Set Bedtime Reminder.
Get a reminder 20 minutes before your bedtime, so you can prepare yourself for sleep.
