How it works
No templates, no sign-up flow, no tutorial. Just add your exercises and hit play.
Type each exercise name and duration. Squats 45s, Rest 15s, Burpees 1m — whatever your routine calls for.
Drop a YouTube URL for any task. The video plays embedded in the timer and stops when time runs out.
TimeTally auto-advances through every exercise, announces each one by name, and shows what's coming next.
Save your workout as a tab. Add TimeTally to your home screen as a PWA and your routine is always one tap away.
Features
Not a generic timer with a workout skin — features that actually matter mid-rep.
Paste any YouTube URL as a task. Follow along with a workout video while the timer tracks your intervals automatically.
"Starting burpees for 1 minute." Eyes on the exercise, not the screen. TTS calls out each task as it begins.
When the timer hits zero, the next exercise starts automatically. No tapping, no pausing — just keep moving.
A beep at the end of each interval so you know to transition even if you're not watching the screen.
Keep HIIT, Yoga, and Strength as separate tabs. Switch between them without losing your custom setups.

FAQ
YouTube embeds work on most desktop browsers and Android. On iOS, browser autoplay restrictions may prevent the video from starting automatically — tap the video once to begin. Voice cues and auto-advance work normally on all devices.
No. Paste any public YouTube URL as a task — no Google account or login required. The video plays embedded inside the timer and stops automatically when your interval ends.
Yes. Set a 20-second work task and a 10-second rest task, repeat them as many rounds as you need, and hit play. Voice cues announce each interval and auto-advance handles every transition — no tapping required.
Once installed as a PWA, TimeTally runs fully offline. Your saved workouts are stored in your browser. YouTube video tasks require an internet connection to stream.
No limit. Add as many tasks as your workout requires. You can save multiple different workouts as separate browser tabs — each with its own task list, settings, and session history.
