This app is ok. It does track your sleep and picks up noises pretty well. It also has good sleep sounds and the breathing is very helpful. However, the options for "how you feel/what you did before bed" are limited, and so are the options for after sleep, such as "got up to use the bathroom" or "had a bad dream", which affect the quality of one's sleep. Also, it crashes for no reason once every week or so.

I've been using this app for 5 days and 4 of those days give me the error message "there is something wrong with the tracking and your sleep data is abnormal". The tracking shows that I was awake 100% of the time that I was asleep. This isn't really helpful, tbh. I wonder if this has to do with picking up noise from my fan or AC. I've tried different locations too. It's hard to have a background noise cancellation feature when you're trying to track noise, but there is room for improvement here.

The app seemed good, but the price was outlandish! They also use the old fake-price trick to make you think you're getting a bargain paying yearly or clicking the "limited-time" offer they present on first run. (These pricing practices are banned in some countries.) It also doesn't have trial to see whether the features are worth the bizarrely high price--which is hard to imagine. If it's worth it to you, more power to you. But I won't support apps that play all kinds of tricks to get paid.
