Gadgetbridge for iPhone? The alternative for the Galaxy Fit3
Gadgetbridge doesn't exist for iPhone: it's an open-source, Android-only app. If you want something similar to use the Samsung Galaxy Fit3 with iOS without Samsung's app, the option is Fit3 Bridge, on the App Store: it talks to the band directly, with no accounts or servers.
Why isn't Gadgetbridge on iOS?
Gadgetbridge is distributed for Android (F-Droid). There's no App Store version, and on iPhone apps are installed from there.
How is Fit3 Bridge like Gadgetbridge?
- It connects straight to the band over Bluetooth, without the vendor app.
- No accounts or servers: your data stays on your iPhone.
- It's built only for the Galaxy Fit3 (SM-R390) and iPhone.
How is it different?
Fit3 Bridge isn't open source: it's an app by an independent developer with a 3-day free trial, then a one-time purchase. In return, you install it from the App Store without building anything, it saves data to Apple Health, and it brings notifications from any app to the band (iOS 27).
