Features & Highlights

“Sleep Cycle: Sleep Tracker” is not just another sleep app; it’s a comprehensive tool designed to help you understand and improve your sleep patterns. Here are some of its standout features:

  • Smart Alarm Clock: This feature wakes you up during your lightest sleep phase within a set time window. For instance, if you need to wake up at 7:00 AM, the app might gently rouse you between 6:30 AM and 7:00 AM, ensuring you feel more refreshed and less groggy.

  • Sleep Sounds: A variety of soothing sounds and melodies are available to help you fall asleep. I often use the “Rain” sound, which creates a calming atmosphere that helps me drift off more easily, especially after a long day.
  • Trends and Statistics: The app tracks your sleep patterns over time, allowing you to identify trends. For example, I discovered that I sleep better on weekends, which encouraged me to prioritize rest during the week.
  • Integration with Health Apps: Sleep Cycle syncs with other health apps, providing a holistic view of your wellness. I found it particularly useful to see how my sleep quality correlated with my daily activity levels tracked by my fitness app.

    I paid for the yearly membership, hoping to get insights into my sleep. Not even 3 months in and I'm uninstalling the app. I wish I had NEVER done the annual subscription. Some features are cool, like the sound tracking for snores. But the app does not register that I'm waking up (even when choosing how I feel waking up) and it doesn't work correctly on my watch. It constantly overrides my home screen and shows the set alarm whenever I turn on my watch. Even during the day after I've woken up.

    I've been using this app for years without issue. Almost a decade. However, I just received a notification to prompt me to get the premium version. I've been using this app all this time because it hasn't pestered me to do so. Update: After 1 too many notifications to get premium on an alarm application, I have decided to uninstall it and just use the alarm on my phone.

    tl;dr you are paying for randomly generated plots This app CANNOT reliably detect whether or not I'm asleep. Twice already I woke up in the middle of the night and used the phone to play an audiobook. Both times the app registered it as sleep talking. Regardless, NEVER buy a 1 year subscription to anything! I can't believe I made this mistake.

    Completely disappointed after purchasing this app. It shows me constantly sleeping throughout the night, even though I know I was awake to use the bathroom and let the dog out. my watch tracks me being awake during those periods, but this app shows no movement or noise. Yes I have the permission on for microphone and have turned on the sensors in the watch app. So disappointed with this purchase.

    stick to regular sleep tracking devices. very easy to start, but tracking isn't the greatest, if you sleep with a fan good luck on the snoring. my watch tracks all this and much much more. Finally got it to link to my Samsung watch and it's not even close. And after I went to cancel, it's hidden in the app, whereas all others are canceled from the play store. 1000% not worth the annual charge. Maybe 30 bucks a year and I'd keep it, maybe.
