  • Game changer

    I've used it most nights for the last couple years. It makes waking up so much easier while feeling much more alert. Can never go back to a normal alarm again.

    I'm still new to the app, and have not made a decision on if I believe the app follows my REM sleep as accurately as it puts on, but the alarm is GREAT. I really do feel better waking up with this apps alarm versus a traditional alarm clock!
  • Get it!!

    By Colintaylorful
    Works so well to track sleep habits!! The samples of me snoring is so crazy to listen to! Very accurate
  • Good for waking up with no drowsiness

    By Matt I guess
    Thinking about switching to android, and when I learned I could get it on the android App Store as well I literally breathed a sigh of relief.
  • Love the free version

    By morrilou
    Wakes me up without a scary alarm sound (or waking up my partner in the process)! I just have the basic, free app and it's great. UPDATED: It seems like sometimes my partner's movement will alert the app before my movement does- luckily I can just change the wake up window to 15 minutes later or so, and it evens out.
  • Nice app

    You don't feel like you've been hit by a truck when you wake up anymore.

    I'd buy this app if it were $50. Use it for a day and see how it helps you wake up at a time you're not tired and you'll feel better all day. Use it for a couple months and you'll have an amazing set of statistics on what days you sleep longest or best, and tons of other interesting things. If you value sleep or want to improve your sleep and therefore your entire life, get this app.
