Sleep Timer Smart Alarm is a free application developed by Reflectly ApS for iPhone users in the lifestyle category. This app is designed to help users wake up refreshed and alert by counting sleep cycles and waking them up between cycles. The app takes into account the average time needed for a person to fall asleep, which is 14 minutes, and provides users with the optimal time to go to bed or wake up.

The app's interface is user-friendly, and it only takes one click to set up an alarm to wake up at the right time. The app also offers subscription plans for its own Premium and the Growth Bundle, which provides discounted premium access to a bundle of the most popular productivity and lifestyle apps. However, these subscriptions are optional annual subscriptions, and the app can be used without them.

Overall, Sleep Timer Smart Alarm is a smart solution for those who struggle with restful nights and want to wake up feeling refreshed and alert.
