If you require consistent ambient noise in order to remain asleep, this app is not for you. It's sleep aid sounds can only be set for up to one hour and then they shut off, leaving you susceptible to being awakened by outside noises. The apps description claims you can set its ambient noise features to stay on all night but it's a lie, there is no such option. Because of this I use a separate device to provide all-night white noise, which makes this app completely unable to track my sleep well.

Hi there! You can use ambient sleep aids all night but you have to use the accelerometer as motion detection for it! To change your motion detection to accelerometer go to Profile > More > Motion Detection > Change to the accelerometer. After that, go to Profile > Sleep Aid > Change to all-night and regular.

So far after a bit over a week of use, I am so-so impressed. No warning after 5 days use that I was going to be charged. I only realized it when after a week I suddenly got charged. I turned on the "who is snoring" feature and it says I have 10 more calibrations, but I have done well over 20 and the progress bar does not advance. But it does cycle so eventually I see it recognized my tagging. It doesn't have a me snoring versus my partner snoring to tag. Detecting me awake is not accurate.

Hi there! You should have received a reminder from Google regarding the charge, if you didn't you will unfortunately have to contact them. Regarding your snoring issue please reach out to us at so we can take a closer look!

I originally paid for this about eight years ago. It was great. It has since changed and costs more. I paid for a one year subscription about a year ago but I wouldn't pay for this again as the alarm has repeatedly failed to go off. I have photos of the alarm and the time far past it, and it's still not trying to wake me. Paid and free it wasn't working properly. I liked the wake up sounds is all but be prepared,, you should set a back up alarm.
