★☆☆☆☆ JABIR CN · Apr 11, 2026
don't install this app. They didn't provide service before we just try this app for free they ask subscription first they can give a 5 or 3 trail without auto payment subscription for free as free trial
★★☆☆☆ Olivia Harrison · May 26, 2026
Although this is a great app, you have to pay for most of the sounds which I didn't mind since the yearly subscription wasn't too bad, I had been using it for a few weeks and went to use it again, and it had kicked me out of my account, so when I tried to log back in it said the password or email didn't match so when I went to reset my password, it said my account doesn't exist so then I tried to see if I used any of my other emails, and it said no accounts had that email so I want a refund
★☆☆☆☆ Selina Ai Lin · Apr 8, 2026
You have to pay to tracker sleep, what's the point of it being a tracker app and requires you to pay?if you. Want just put it as otter music.
