Works offline
A workout app that works with no connection.
FitBoost builds your plan on your iPhone rather than on a server, so a workout you already have does not need a connection to run. Saved sessions, the guided timer and your progress all work with the phone in airplane mode.
Yes, saved workouts and the timer work offline, because your plan is generated on the device rather than fetched from a server.
Why most fitness apps stop working
If an app streams its video or asks a server what your next workout should be, then a basement gym, a hotel lift or a plane is enough to stop your session.
That is an architecture choice, not bad luck.
Where FitBoost puts the work
The planning runs on your phone. Deciding today’s session, choosing the exercises, adjusting to what you completed last week, all of that happens on the device, from data already stored there.
- Saved workouts open with no connection
- The guided timer runs offline
- Completed sessions are recorded on the device
- No video to buffer, because the app ships no video
Where you will notice a difference
Being precise about the limits: a run that records a route uses your phone’s GPS, which works offline, but the map imagery around it does not.
