Run the workout in the HiittiiVai phone app and follow and control it from the watch, without reaching for the phone. • See the phase (sweat, rest, round switch) in its colour, the time left in it, your round and move, and the total time left • START starts, pauses and resumes the workout; BACK on a paused workout asks before ending it • Touch is ignored during a workout, so a sweaty wrist or a sleeve can't pause it by accident • Vibration and tones in the last seconds and at every phase change, and the screen lights up at each change • Open the app mid-workout and it catches up at once Requires the HiittiiVai app for Android (Google Play) and Garmin Connect on the same phone. Choose this watch once in HiittiiVai's settings (Settings Watch). The workout runs on the phone; the watch shows it and sends your button presses. No account, no ads, no tracking.
