Doesn’t work at all

It just syncs nothing

Crashes with iOS 26

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

Does not sync steps anymore :(

Used to work but wasn’t update for three years and stopped functioning

サポート放棄?

9月にsyncsolver.comのドメインも利用できなくなり、同期更新できなくなりサポートサイトすら繋がらず

Doesn’t work

I only asked for weight data to be transferred from Health to Fitbit. The advanced page is all black. The sync says “nothing to sync”. It hasn’t synced any data. I wouldn’t waste money on this.

Steps doesn’t sync - 2025

All the other reviews are still accurate. The steps don’t sync. Would like my money back also.

使えない

ヘルスケアアプリからFitbitに同期できません。返金してください。

Worked in the beginning then stopped

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

Funktioniert

Inzwischen funktioniert die App ganz gut. Alle paar Wochen muss ich die App installieren und über Google aktualisieren. Ansonsten läuft sie einwandfrei.

This app doesn’t do what it says it will?

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.

Doesn’t do what it says it can do

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

Poor

Very poor, doesn’t sync properly just doesn’t really work.

Doesn’t work

App doesn’t work, when you try to sync it says it’s successfully completed sync immediately but then afterwards it also says that nothing has been synced in the past.

C’est du vol !!! Nul !!! Ne pas acheter

Ne fonctionne pas alors que payante.
C’est du vol !!!
Vous devriez avoir honte

This does not work to move weight from health to Fitbit

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 at all

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

Used to work. May need some updates

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.

Don’t waste your money

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.

Continually loses connection

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.

Way to complicated

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