Really great, will give full 5 stars when the "wake time" section is corrected (I have sent an email) I have been feeling a lot better in the mornings when I wake up in line with my sleep cycles Does have ads but it doesn't bother me since you only use the app for a short time each night

About this app

Does your phone alarm wake you up angry, make you mad for the whole day, and sometimes not even go off? Our sleep calculator will help you fall asleep and wake up in the most natural way and help you get your day started full of energy and with a smile on your face.

Waking up in the middle of a sleep cycle can leave you groggy and ruin your whole day. Our app helps you find the perfect moment to wake up or fall asleep in order to maximize your sleep and keep you fresh all day. A normal sleep cycle lasts 90 minutes and, using that as a foundation, our app calculates the exact moment when you’re brain and body are ready to awaken.

Our app uses natural sounds to slowly bring you out of your sleep cycle and make sure you are wide awake. Once you have selected the sound of your choice, the sound will be played slowly and steadily, increasing in volume, for one minute.
There are eight natural sounds you can choose from:

- Bird Song
- Birds in the forest
- Ambient loop
- Gentle piano
- Seaside Sounds
- Garden
- Rapid river
- Kenyan Savannah Grassland

The app allows you to choose:
- when to wake up
- when to go to sleep
- when to wake up if you sleep now

You can also set up alarm with the app and browse all "Sleep Time" alarms inside our app.
This app is perfect for modern people who often don't get enough sleep. This app allows you to maximize the amount and quality of sleep you get and make sure you are never late (or groggy) to a class or meeting again!

Features:
- calculates when to wake up and when to sleep to feel great
- calculates when to wake up if you are already asleep now
- add an alarm by clicking on a time
- light and Dark themes
- choose from 8 natural sounds
- browse all "Sleep Time" alarms inside the app
