Custom Intervals
Set your own prepare, work, rest, and complete phases. Build routines that match your training style.
Interval timer for people who train
Don't count reps. Count down.
Tempo is a sharp, private workout timer for HIIT, Tabata, circuits, boxing rounds, and any routine where missing the next interval ruins the flow.

Training controls
Everything you need, nothing that asks for your email.
We built Tempo because interval timers should help you train, not onboard you into a platform. The controls are deep enough for custom sessions and simple enough to use between sets.

Rich Sound Cues

Native Notifications
Enable workout cues and Tempo will keep you on track with local notifications, even when backgrounded.
Dark Mode
Easy on the eyes at 5 AM or in a dim gym. Tempo respects your system preference or lets you toggle manually.
Works Offline
No internet required. Tempo runs entirely on your device, so your workout is never interrupted by a signal drop.
Real app screens, no mockups
Fine control without spreadsheet energy
Tempo has the controls serious interval training needs, but keeps them out of the way when it is time to start.
Routine Builder
Make the timer match the session
Prep, work, rest, rounds, and workout cues live in one focused sheet. Save the routine, use it now, or come back to it later.
Sound Cues
Hear the next move before you look down
Choose real samples, generated tones, or system sounds. Set warning timing, play length, loop length, and volume per interval.
How it works
Three steps between opening the app and finishing your first round.
1
Set it up
Open the routine builder and dial in your intervals. Prep time, work time, rest time, rounds — however you train.
2
Hit start
The large, high-contrast timer keeps you focused. Phase labels, a progress ring, and haptic cues keep you on track.
3
Save and repeat
Love a routine? Save it. Next time, load it in one tap and get straight to work.
Your data never leaves your device
We believe workout timers should not be data collection devices. Tempo is built to be private by design.
No account required
Open the app and start training. Optional account features may come later, but local timer use stays available.
No cloud storage
Your routines and settings live on your phone. We do not run servers that store your workouts.
Minimal network use
The current release checks version policy and keeps routine data local. Any future monetization changes will be disclosed before release.
