SetGrip keeps its database and its complete exercise catalog, including all 1,151 demonstration videos, on the device. Nothing in a workout is fetched from the internet, so a basement gym with no signal changes nothing.
Only four things use a connection, and none of them block training:
- iCloud sync to your other devices catches up when you are back online.
- Premium purchases and restores go through the App Store.
- Feature and exercise requests (a Premium board) need a connection to load.
- Anonymous analytics are sent when possible and silently skipped otherwise.
The Apple Watch app talks to your iPhone over Bluetooth or Wi-Fi, not over the internet, so it also works in an offline gym as long as the iPhone is nearby. See does the Apple Watch app work without the iPhone?
