Works so inconsistently, it's sort of pointless
Data is lost after app updated
Doesn't connect to the sleep light properly, can't control light or music, alarm setting doesn't work, many buttons seemingly do nothing. The only sound I can get the light to play is the waves sound which sounds unlike any waves I've ever heard. The LED when dim flickers annoyingly. I tried running the sleep tracker for 15 mins - it crashed then told me I'd slept for 7 hours. When trying to change settings for the light on the app it frequently tells me the light isn't connected even though I can see it on the network and also see that it's merrily sending data out into the internet even though it doesn't possess any data to send. I just don't understand how an app and a piece of hardware can be so bad and I frankly smell a scam. Avoid!
Long press of the main button that is supposed to start the sleep mode stopped working after the last update. The app also does not work well with the European summer time since I have to set the alarm to minus one hour all the time.
Previous version was better. Now, we have a bright white screen at night. The new main screen also requires spectacles and small fingers. Still, the power drain is big issue: why the app needs to run during the day?
I had reasonable expectations after buying the (the very pricey) nox sleepace which have not been met. This app routinely crashes through the night, the limited sounds have a noticeable pause before they replay, there is no clear instruction on how to use the app, and the overall interface is not well thought-out. I would recommend finding another option if you are looking for asleep monitoring and sleep aid system.
