  • Works perfectly

    By Tomas Rib
    Super efficient and accurate. Really does the job
  • Good app!

    By JJ.KJ
    This is very good app. Everything works. Just one tiny request. I would just like the app to be compatible on the Apple Watch. Other than that, brilliant!
  • We have a snag

    By Pete 72
    What happened to the the pulse reader? It just doesn’t work any more. I can literally rest the phone on a finger and wait and it doesn’t manage to get a pulse, apart from that, all good
  • Wakes me perfectly

    By Emscuit5

  • Does not work with iPhone X

    By jfr456
    It used to work fairly well with my iPhone 7. But it no longer works since I switch to iPhone X. It basically produces completely random sleep records.
  • Great App

    Let’s you pay more attention to your sleep patterns
  • Not sure it works

    By Emzy56
    Im pretty sure this app tracks my husband and not me, for instance it has recorded me snoring and shows me in a deep sleep but i have actually been awake listening to my husband snoring at that time. It also tends to wake me up in the first 10mins of the 30min alarm window and a couple of times i have been dreaming, in a pretty deep sleep, so i end up feeling more groggy. On a plus side i bought this app ages ago and recently re-downloaded it so now i get the premium features for life.
  • App doesn’t work

    By kib10
    This app does not work-I was ill in bed yesterday and it said I did 1,476 steps which is completely false. Also said I was asleep when I was 100% awake and it does this frequently. I guess it works on your breathing so if you are relaxed in bed but not asleep, it might presume you are in fact asleep.
  • Took money out of my account without notifying me

    By EmH1997
    Charged me £24.99 without telling me it would do so
