Frequently asked questions
- Why do teams switch fitness APIs?
- The usual triggers are a deprecation or migration (Google Fit is winding down; the legacy Fitbit Web API is moving to the Google Health API), an access barrier (Garmin's developer program needs Garmin's approval, now as Starter and Enterprise Access), cost or a membership requirement (Oura, WHOOP), missing data or platform coverage, or wanting one integration instead of many. Each alternatives page below walks the specific trigger and the realistic options.
- What's the fastest way to cover many wearables at once?
- Use a health-data aggregator (Terra, Junction/ex-Vital, Rook, Spike): one integration and one webhook normalizes data from many devices, so you don't build and maintain a separate integration per provider. The trade-off is a recurring cost, and for some providers you still register your own developer credentials.
- Are these alternatives drop-in replacements?
- Rarely. Different providers expose different data, auth models, and access requirements, so a switch usually means re-doing OAuth, re-mapping fields, and asking users to reconnect. The alternatives pages flag where a move is genuinely easy versus where it's a real re-integration.
