Need uptown to upload my downloaded data
They say it cannot download all data because Fitbit does not allow them to get it, of course they don’t.
You should implement a function to upload from my downloaded data file from Fitbit. I will be waiting.
Sync function great Aug 2025
I used to love this App. Worked great with Versa and Versa 4 Fitbit for several years. But as of Aug 2025 sync partially fails, Fitbit not available (200). Reinstall etc no good. I’ll try to contact Dev.
App doesn’t work
水分の同期が出来なくなった!
iOSのバージョンアップでヘルスケアの水分関連に何か仕様変更があったのかな?
対応して頂けると嬉しいです。
この件、解決したら星4〜5なアプリだと思います。
It no longer works
However, my recent experience has been disappointing. Over the past week, I’ve encountered a persistent Sync 200 error that has rendered the app non-functional. Despite multiple troubleshooting attempts,including deleting and reinstalling both the Fitbit and Sync Solver apps, and logging in and out of accounts, the issue remains unresolved. This error has disrupted the syncing of critical data such as dietary intake, resting calories, and active calories, which are central to my health tracking routine.
At present, the app is no longer performing as advertised. For users who rely on accurate and consistent syncing of calorie related data, I would advise caution. Until this issue is addressed by the developers, the app may not meet expectations or deliver the functionality it once did.
I hope the Sync Solver team can resolve this issue soon, as the app has historically been a fantastic solution. But for now, prospective users should be aware of this limitation.
