I have not seen such a low-grade designed app in quite a while. Absolutely zero detail information and the graphing scales are something a child might have made using Windows 3x 20 years ago in school.. oh and you can't sync this with anything without downloading third-party sync software. The only way that you can read this data like heart rate info correctly is to sync it to Google fit and view it there to be able to scroll through the rate during the day. Costs more money for that.
