  • Range of sleep aid sounds needs improving

    By ElmerTPussycat
    Almost none of the sleep aid sounds are soothing. The sounds need a lot of improving. Also, there seems to be no screen menu so you can easily get back into the sounds after you’ve settled down to sleep but realize you want to try to make and adjustment. The app doesn’t cater to the end user for their ability to make changes and tweak it. Additionally, I hate having to have my cell in my bed while sleeping. Why can’t it be on my nightstand? It has fallen off and onto the floor at night. I don’t know if the electronic stuff is bad for my body and try to avoid prolonged physical contact and so having it that close to me while sleeping is unnerving. Also, it has to be “plugged in” to work at night. I worry that’s ruining my battery life! Sorry because I wanted to write a good report... The sleep charts are great and informative and I look forward to using them and to enjoying better sleep!
  • would like to see notes

    By wingwalker01
    it would be a fantastic ability to be able to leave a note for myself when i wake up on those mornings after a night of sleeping so hard that i wake up confused and/or forget why i needed to get up.
  • Does not track accurately

    By akajduene
    I have had multiple times where I wake up in the middle of the night, toss and turn for 1-2 hours and then finally get back to sleep. The next morning the data during this time period is recorded as deep sleep or a combination of light and deep sleep. Sleep quality is recorded as 69-75% these nights. Love the concept, but as a sleep tracker it’s just not accurate.
  • So interesting!!

    By Kaylamj533
    I have no way of knowing if the app is actually accurate, but I enjoy the free version! it’s so interesting to see how my day affects my sleep cycles. if you enjoy knowledge for knowledge’s sake, is recommend the free version.
  • Philips Hue stopped working

    By JasonBrady
    Overall the app has been great, and I’ve come to rely on the hue feature to gently wake me up because I have no natural light in my room. It hasn’t worked for about a week, possibly with the last update. Please fix!
  • Needs these “smart” features

    By PolloTec
    Please add the ability to click a sleep hours preset button (e.g. 7, 8, 9 hours) on the sleep cycle wake up time activation screen to auto start a wake up timeframe. Additional capabilities would allow for the automatic wake up time based on sleep analysis / heart rate data and other factors to determine how much sleep the user needs based on all the given data (age, weight, gender, sleep quality, heart rate, etc...) and wake up the user when fully rested.
  • Very much enjoy this

    By half of an egg
    Now I can wake up at 4:30 AM so I can be fully awake when I need to be.
  • Wakes me up at inappropriate times???

    By kenneth231
    I set this app to wake me up between 8 and 8:30am today and the alarm went off at 6:15am. I used this app for 4 nights and it woke me up way before my specified wake up time on 2 of them. Uninstalling.

  • Help/Question Snoring

    By M@dd0ggy
    This app is wonderful. The only reason I rate it 4/5 stars is because it records my snoring but I can’t even listen to it unless I pay for the premium. Both my parents and grandparents (on both sides) have sleep apnea so it’s important for me to know if I snore. I am also a very poor college student so I can’t afford to pay for the premium subscription. Would it be possible in a future update to be able to listen to the snoring that the app recorded w/out the premium subscription?
