## Interval Timer by STRNTH Description
Interval Timer by STRNTH is a free interval timer for HIIT, Tabata, EMOM, AMRAP, boxing rounds, running intervals, stretching and more. Build any timer you want with no fixed structure, then run it hands-free and read it from across the room.

BUILD ANY TIMER
- Add as many steps as you like, each with its own label, duration, colour, sound and voice.
- Group steps into repeat blocks so a round loops as many times as you need.
- Link separate timers together to chain a warm-up, workout and cool-down into one session.
- Start from a template: Couch to 5K, Tabata, HIIT, 7 minute workout, EMOM, AMRAP, boxing rounds, Pomodoro, box breathing and full body stretch.

RUN IT HANDS-FREE
- A giant readout inside a progress ring, sized to read from across the gym.
- Full-screen colour per step so you know your phase at a glance.
- Voice reads each step and announces what is next before it arrives.
- Sound cues on the last three seconds, plus beep, go, switch, rest, bell, horn, gong and whistle tones. Import your own sounds too.
- Optional spoken 3-2-1 countdown, a cadence metronome from 60 to 180 BPM and haptic feedback.
- Choose what the screen shows: interval time, total time, interval count, the clock or heart rate.

MORE TOOLS
- A countdown tab with quick presets for a fast single timer.
- A stopwatch with laps that highlight your fastest and slowest split.
- Light and dark themes and your own custom step colours.
- Share a timer as a link or a file, and import timers others send you.

ACROSS YOUR DEVICES
- An Apple Watch companion runs your timers on the wrist with colour and haptics.
- Pair a Bluetooth heart rate strap to see live BPM, zones and more while you train.
- Save finished sessions to Apple Health as workouts.
- Back up your timers to your private iCloud.

FREE, WITH A ONE-TIME UPGRADE
Interval Timer is free and supported by ads. A single 9.99 purchase removes ads for good. No accounts, no subscriptions, no cloud sign-in. Your timers stay on your device.

Part of the STRNTH family of training apps.
