Intervo: Interval Timer

Big, bold interval timing that's free forever. HIIT, Tabata, circuits — with voice coaches, streaks and widgets. Go Pro once, own it for life. No subscriptions.

Intervals so simple you'll actually use them. Big. Bold. Loud when it counts.

Intervo is the interval timer you can read from across the room — huge numbers, punchy colors, and voice cues that tell you when to work and when to rest, so your eyes stay on the workout, not the phone.

EVERY TIMER IS FREE. FOREVER. Set up warm-up, work, rest and rounds in seconds. Run HIIT, Tabata, circuits, 400m repeats, yoga holds — anything with intervals. No account, no ads, no limits on timing.

HEAR EVERY CHANGE • Six voice coaches (calm to full hype) in ten languages • "Let's go!", "Rest", "Last round" — plus haptic buzzes and countdown beeps • Keeps talking with the screen locked or music playing

BUILT FOR THE GYM FLOOR • Numbers readable at arm's length, colors that switch with every phase • Tap anywhere to pause, skip intervals with a tap • Start straight from the home screen with quick actions

GO PRO. ONCE. (optional one-time purchase) • Save unlimited workouts — name them, reuse them • Stats, streaks and history — see every session you've crushed • Home-screen widgets: your next workout, one tap from starting • Every future feature included.
