Intervall

Most interval timers assume you can grab your phone every time a set ends. At the gym, that’s annoying. Chalk on the screen. Gloves on. Hands full. You’re mid-set and the phone is face-down on the floor — so you either wipe it, unlock it, and hunt for Start… or you just guess. Intervall : Timer for Workouts is built for that exact moment. Thumb up in front of the camera and the next interval starts. Open palm to pause. Both palms to finish. Prefer talking? Say START, STOP, or FINISH. Prefer a button? Tap still works. No watch required. No account. No cloud. Camera and mic stay on your iPhone — Vision and Speech run on-device so it works offline in a dead basement gym. What you get • Huge high-contrast timer you can read from across a rack • Dial your interval length like a clock • Rest between sets when you want it • 3·2·1 before work (on by default; change it in Settings) • Themes you can actually see under gym lights — plus custom colors This isn’t another cluttered HIIT planner with twenty screens. It’s one job: keep the clock moving when your hands aren’t free. IN-APP PURCHASES This app is free to download. Full Pro access — including hands-free gesture control, voice commands, themes, and the complete timer experience — requires a separate In-App Purchase. Choose an auto-renewable Monthly or Yearly subscription (each includes a 7-day free trial), or a one-time Lifetime unlock.
