Sort of works but doesn’t sync automatically. Step counts totally wrong – Sync Solver - Health to Fitbit Review

Despite what the app claims, it does not sync to Fitbit automatically. You have to manually sync it. Update: the step counts transferred to Fitbit are wildly inaccurate. In a day where I have 5,000 steps worth of activity, only 1200 steps would sync to the Fitbit. This may be due to me having both an Apple Watch and motion tracking on the phone, but regardless of the limitations the app has to deal with, it doesn’t do the things it claims to well enough to justify using it. The fact of the matter is that with the way things are between Apple and Fitbit at the moment, you have to pick one or the other. This app is a bandaid at best and comes with sufficient compromises that it is not worth using, despite the admirable efforts by the developer
