UPDATE Jan. 29, 2022: this is the 3rd time AT LEAST that this app has erased my data. The app asks me if I even STARTED fasting yet and the water count is ERASED with NO WAY to re-input the erased info. UPDATE MARCH 8, 2022: same crash has happened multiple times since. I've sent feedback with ZERO response. DONT INSTALL. And certainly dont waste your cash. Pencil & paper would do a better job. UPDATE 3/11/2022: ive emailed and sent screenshots. I'm not going to keep dealing w/ this. UNINSTALLED
