The scale (Robi S15) works well with the app. But it doesn't sync any data through Health Connect to Fitbit as advertised. The Fitdays app has all the Health Connect permissions it can be given, but it just doesn't write any data to it. In the Health Connect app I can see the recent access logs and Fitbit is regularly reading data, but Fitdays doesn't appear in there at all. Tried disabling and reenabling the sync, taking new measurements, etc. Nothing helps. May have to return the scale

do not buy a scale that is connected to this fit day app this is my third time being completely locked out I've had to use two different email addresses when you select forgot my password it'll send you a verification then it won't recognize its own verification and then I tried to use the reverse method and send them an email with the verification code as directed still can't get in I've lost all of my fitness data twice now in the past year

Easy to use, but no data sharing. The integration with other apps no longer works, which limits how useful the app and scale are to me now. The whole reason I bought the scale is to have data upload without me having to manually log it.
