Sleep Time - Cycle Alarm Timer is an Android application developed by Oleg Filimonov that helps you wake up feeling great by calculating when to wake up or fall asleep based on your sleep cycle. With its simple material design, the app is built for speed and efficiency.

The app provides two main features: calculating when to wake up if you go to sleep now or at a certain time, and calculating when to sleep if you want to wake up at a specific time. Additionally, the app includes notifications for when to wake up or go to sleep and factors in the time it takes to fall asleep in its calculations.

Overall, Sleep Time - Cycle Alarm Timer is an excellent tool for those who want to improve their sleep cycle and wake up feeling refreshed. If you encounter any issues or have any feedback, the developer has included a Feedback tab in the app drawer for convenient communication.
