The app is good. however the free version doesn't allow to export your actual sleep data. It will not upload the sleep data the google health connect. I understand that the developer wants to earn money with sleep coaching; the sleep tracking and data forwarding should be free of charge. Remember that this algorithm was developed with public funding.

absolute rip-off. The app constantly fails to fetch the data at the end of the night, meaning another night wearing that sensor for nothing.
