Vendor-Update-Survivable Garmin Connect Replacement For iPhone Users Burned By The 5.21 Mass-Unpairing Bug
Garmin Connect 5.21.0.28 on iOS 26.2.1 unpaired Forerunner 965, Enduro 3, and Fenix 7 devices from their owners' phones in late January 2026. Even after the 5.21.1 fix shipped, users had to manually re-pair, and many found their Garmin Connect+ subscription paid for nothing during the outage. Build a third-party iOS sync companion (or a simple watchdog that snapshots and restores pairing state across Connect updates) so users aren't dependent on Garmin's QA cycle for the watches they paid $700-1100 for.
Don't try to clone Connect, it's too big. Win on one verb: 'restore my pairing.' If Garmin breaks again (and they will, this happened in 5.21 and again in 5.21.1) you become the app every angry runner installs that week. Newsletter the user the day a new Connect version hits.

Garmin owns the BLE pairing handshake and there's no documented third-party sync app for iOS. The opportunity may not be a full Connect replacement (Garmin protocol is partially closed), but a 'pairing notary' that periodically exports your devices, custom data fields, and IQ apps to local storage so a botched Connect update can be rolled back. Also: Garmin Connect+ at $7/mo with a recent five-month track record of 'still not worth it' is itself a soft signal that there's pricing room for a paid third-party companion.
