Health Sync seamlessly syncs your data between health and fitness platforms.
• SYNC FROM: Apple Health, Coros, Google Health (Fitbit), Garmin Connect, HUAWEI Health, Oura, Polar Flow, Strava, and Suunto.
• SYNC TO: Apple Health, Coros, Google Health (Fitbit), Guava, HUAWEI Health, Intervals.icu, Runalyze, Selfloops, Strava, Suunto, and TrainItAll.
It will sync data from the time you first use the app. Historical data (all data before the day of installation) can be synced after the free trial period. With Garmin Connect you can sync the last five years of activity data, and the last two years of other data (steps, sleep, heart rate etc.). With Polar Flow you can't sync historical data.
The sync runs automatically in the background a few times per hour (due to iOS restrictions on background processes). Activity GPS data is synced to Apple Health when the phone screen is unlocked.…

No review analysis published for this app.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
Added support for 'Recovery HRV' data from Apple Health on iOS 27. Health Sync will prompt you for the necessary permission so you can keep your recovery trends seamlessly updated. Refined the visual design and layout specifically optimized for iPhone DUO.

health-sync-by-appyhappsWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
