Track cardio with the full-screen timer

Operational steps

1
Start a workout and add an exercise in the Cardio category, such as running or walking.
2
Expand the exercise card and tap `Start cardio timer`.
3
Check the displayed goal. A set with a planned duration shows its target; otherwise the timer stays open-ended.
4
Tap `Start cardio timer` again on the full-screen view to begin timing.

`Pause` stops counting without losing the time already tracked.
`Resume` continues from the accumulated duration.
The progress bar compares elapsed time with the planned set duration.
Reaching the goal does not close the timer. You can keep going and save the actual duration.

On iPhone with iOS 17 or later, the timer switches to a dedicated cardio Live Activity on the Lock Screen and, on supported models, in the Dynamic Island.
On Android, an ongoing notification uses the system chronometer while FitLog Pro is in the background. It disappears when you finish or discard the session.
If the companion app is installed on a paired Apple Watch, the Watch automatically shows the exercise, elapsed time, pause state, and goal.
Start, pause, resume, and finish stay synchronized from the full-screen controls on iPhone or Android.

Tap `Finish and save` when the activity is complete.
FitLog Pro saves the actual duration plus start and finish times to the first incomplete cardio set.
The set completes through the normal workout flow, so drafts, history, and sync continue to work as usual.
The cardio timer measures the activity. The separate rest timer still handles recovery between sets.

If you try to close a started timer, FitLog Pro asks before discarding your progress.
If the app briefly moves to the background, elapsed time uses the wall clock and catches up when you return.
To avoid losing a session, use `Finish and save` before force-closing the app or turning off the phone.
