Sync Solver - Health to Fitbit

The app will not even open now. Since updating to iOS 26 this app crashes immediately when you try to open it. Doubt the developer does anything as it hasn’t been updated for 4 years. If officially declare this one dead

Worked when I first got it but stop syncing data since Jan 11

I bought this app to try to sync my Fitbit data with the Step Up app (it says it will do it indirectly through Apple health) so I don’t have to carry my phone around to participate in a work step challenge. But it doesn’t do this. And there aren’t a lot of settings to troubleshoot with. It just simply does not do what i paid for it to do.

App is supposed to sync data from Apple Health app into Fitbit, but does not do that

Have tried FAQ’s resetting, reloading, nada. The Fitbit to health works, but not this one. App support button is broken- hoping to get a refund

Doesn't work as advertised.. I see 0 steps after repeated attempts at syncing.

As some of the other reviewers noted it used to sync throughout the day but no longer does. It also doesn’t sync steps accurately. For $4.99 and one of the only paid apps it should work much better. I’ve had this app for a long time and it doesn’t feel like the developers have tried to keep I current and fix the bugs.

Occasionally I leave my Fitbit on the charger when I leave home. I got this, hoping I could do what it says it does and move my data from Apple Health to Fitbit. This app is both overly simplistic and tedious. You start on the main screen with a giant Sync Now button. If you do this without taking any additional steps it can erase a lot of data from Fitbit; you have to go to Advanced Settings first and tell it how far back you want it to go. But, oops, actually, now it’s not working at all! “Nothing to Sync!” it says. “Already Synced” it promises. You check Fitbit and nothing has changed, but Apple Health says 8,000 steps. It’s terrible. Save yourself five bucks. Don’t bother.

As the title says - and does not tell you it’s happening. So while it works when it works, it will just stop working for no discernible reason. And this has happened over several months (almost a year) now, so it’s not being fixed in updates. What happens: 1. Connect Sync Solver to Shapa & Fitbit 2. Sync - for a month or so, works beautifully. 3. Check weight in Apple Health - yep, that also works. 4. Wait. 5. One day, use Sync Solver, get “nothing to sync” 6. Check Apple Health - yep, that still connects fine to Shapa. 7. Check Fitbit - nope, nothing getting synced. 8. Delete Sync Solver. 9. Re-add Sync Solver. 10. Re-connect Sync Solver. 11. Repeat steps 1-10 ad Infinitum, ad nauseam.

Good money spend on bad rubbishy. Add a tutorial to the app
