  • Great app

    By Dillan.Greene
    Overall a great app. - easy to use - nice layout - accurate sleep journal ( I use it everyday no matter what.)
  • Can’t upgrade

    By Jeremiah5409
    Haven’t used the app yet, but want to track my sleep/wake cycle. I need premium for that. When I try to upgrade I get a spinning circle indefinitely. I can’t even pay to use the app. I’ll have to use something else. Shame too because I was looking for a very gentle wake up and the tones here were right up my alley. Oh well. 🤷‍♂️
  • Sleep aid can’t run all night anymore?

    By Katest7711
    Have been using this app for ages and I loved it dearly.... until the most recent big update. I wake easily in the night and have always had my rain noise play all night so I could drown the sounds of my husband snoring, my cat being a jerk, etc. now they decided I can only have 90 mins of sleep aid and I am unhappy about this change. I can turn it back on ... but I have to wake up a little more, grab the phone scroll through the sound options.. then I struggle to fall back asleep again. TERRIBLE UPDATE!
  • Only registered my parters sleep.

    By Sammitches3
    So, my partner snores, LOUD. And all of the audio from my sleep analysis is his snoring recorded. I says I’m snoring but it’s him and the sleep pattern it tracks ends up only being his. We have two very young children who are up several times in a night and I was out of bed six times throughout the night last night, and managed an entire 2.5 hours of sleep...but my app says I was sleeping for 9 hours with a nice big long REM cycle at the end. Glad to know my partner is sleeping well, and that he snores. I don’t think I could have guessed except that I was up all night meanwhile. The app thinks he is me I guess.’s a great idea for an app and might be awesome if you own a wearable to help it out a bit but with the native tech in most wearables today this app becomes irrelevant. Good if you live alone and want to know if you snore and when. It did a great job recording 7 hours of nonstop snoring that wasn’t mine.
  • Disappointed with update 😣

    By Montanajjr
    Loved the app before the latest update. Now it conveys less information and requires more pages to get to it. Please return the written summaries for the monthly, yearly & all-time graphs not just the last 7 days. Graphs do not even show the average line. Nothing but pictures now that require extrapolation, no actual numbers provided.
  • Snore feature is inaccurate

    By madisonxjane
    On nights I sleep without my husband I get 0 minutes of snoring, but when he is there the app picks up his snoring. I want to be able to listen to the recording, and then the app should have something that asks “Was this you?” Or “Was this correct?” If it wasn’t me, I want to be able to say no and have the time removed from my statistics. I like the idea of this app, but there should be an option to give the app feedback so it can improve its analysis.
  • Woke me up at same time rather then during light sleep

    By Lockenschopf
    The app worked only a few times. The entire last week it woke me up at the same time everyday, right after I drifted into deep sleep. 20 min earlier and it would have been light sleep. Both times are within the alarm window. It actually made my sleep worse and I never have been so tired before in my life.
  • Excellent App

    By zep100
    Hue lights integration makes this app a clear winner in my book - especially in the winter. It really helps maintain my sleep schedule. Couple minor features I’d like to see - - when setting the alarm time, show how much time until wake up (I like that feature in apple’s app) - go to bed reminders so you get a full nights rest (again, apple got that right in their app) Either way, I’ve been using this alarm for many years and it’s a five star app in my book.
  • keeping track

    i’m really able to see how my sleep affects me in a day
  • Changes

    By GMS-VB
    I love the new look, but every since the update it doesn’t gradually wake me up like it used to. I just wish it would have duplicated my settings during the update instead of it taking a few weeks and a few bad mornings for me to adjust the wake up settings.
