TimerFit: Interval Timer
Simple, on-off workout timer
Free · Designed for iPad. Not verified for macOS.
From a simple flip-on timer to interval circuits that show you each move. Built-in Tabata, HIIT & EMOM presets. No ads. Start now.
Just what you need for your workout — nothing more. TimerFit started from one simple idea: a beautiful timer you flip on and off while you train. It grew into a clean, focused interval timer for real workouts.
■ Two timers, one app
• Simple Timer — set the time and go. A big, clear progress ring shows time at a glance, and your go-to durations are one tap away under "Recent."
• Interval Circuit Timer — prepare → work → rest → next round, all handled automatically. Hands-free flow from start to finish.
■ A different move each round — follow along
Burpees, mountain climbers, jumping jacks, squats… each work interval shows the movement and a short form cue, big and clear. No more "what's next?" — just move.
■ Ready-to-go presets
• Tabata (20s work / 10s rest)
• HIIT (40s work / 20s rest)
• EMOM Burpees
Tap and start. Perfect for beginners.
■ Build your own routine
Set work/rest durations and rounds your way. Add your own exercises with a custom icon, name, and form cue. Your routines are saved for next time.
■ Signals you won't miss
Sound and haptics on every interval change, plus a 3-2-1 countdown before each one ends. Stay on track without staring at the screen.
■ A glance at your Lock Screen
• Lock your phone — the current interval and time left stay on the Lock Screen and Dynamic Island.
• Tap a Home Screen widget to start your go-to routine instantly.
■ Right on your wrist with Apple Watch
• Start from the watch alone — no phone needed. Presets and the routines you build on iPhone sync straight over.
• Drop your wrist and let the screen sleep; the timer keeps running.
• A tap on the wrist at every interval change, so you never lose the flow.
■ Stay motivated with history
Completed workouts stack up in the History tab — see your total count, total time, and this week's activity at a glance.
■ Clean by design
• Dark mode by default, easy on the eyes (Light mode too)
• No ads · No account
• Keeps the screen awake during workouts
• iPhone, iPad & Apple Watch · English/Korean
Home workouts, CrossFit, core, stretching — or just a 3-minute timer. For every moment that needs one.
