Heart rate. Still useful although that. ### 3/5 — I’m hear putting you on *2025-12-06, version 2.2.1* The goat what I wrote cause fire and smoke ### 1/5 — Overwrote real data with junk *2025-11-23, version 2.2.1* This imported my historical data, which was great, but it didn’t stop there. It continued right up to today, overwriting real data with junk. ### 5/5 — Reliable sync app *2025-10-28, version 2.2.1* This app does what it says and it’s free. I’ve tried several others and ended up deleting them, same day. This actually works and has more more data type options, all free. ### 5/5 — Best free Fitbit sync app *2025-10-24, version 2.2.1* I tried more than 10 Fitbit sync apps, and this one was by far the most reliable and easy to use. All the other ones either didn’t work or required paid subscriptions. ### 3/5 — Very buggy *2025-10-24, version 2.2.1* This app sort of works but ONLY if you literally just downloaded it. I keep having to delete it and redownload it just to get it to sync anything. I guess I’ll use this until I find something better or decide to pay the $60 to use another app. At least this one’s free. ### 3/5 — Yesterday data is being deleted in apple fitness. Why is this happening? *2025-10-11, version 2.2.1* Every day I sync my data with your app the yesterday data is disappearing? Why is this happening? ## Frequently asked questions about SyncFlow Health ### What does SyncFlow Health do?
