How long should I hold a stretch?

For general flexibility, 30 seconds per side is the most commonly recommended hold, repeated 2-4 times. ExtendTimer defaults to 30 second holds with 4 repetitions.

Yes. Single stretches and routines of up to 2 stretches are free forever, with no account required. Pro upgrade unlocks unlimited routines and the full sound studio.

Does ExtendTimer work offline?

Yes. ExtendTimer is a progressive web app: open it once while connected, ideally installed to your home screen, and it keeps working offline after that, including all sounds.
