What is Kairox?
A no-touch workout timer that runs the session for you.
Build or import a workout, press start, and Kairox guides every set, round, rest, transition, rep target, and side by voice.
About Kairox
Kairox is a no-touch workout timer that turns a workout plan into a guided session. Build or import a workout, press start, and Kairox calls the sets, rounds, rests, reps, sides, and transitions so you can train without checking your phone between movements.
The problem Kairox solves
Most people do not fail because they lack exercises. They lose structure once the session starts.
- Losing count of sets or rounds.
- Resting too long between movements.
- Checking the phone constantly.
- Forgetting the next exercise.
- Skipping left or right side work.
- Following workouts from screenshots, notes, or captions.

Start from polished templates for HIIT, EMOM, AMRAP, strength circuits, boxing rounds, mobility, and more.
Voice-guided cues
Hear work, rest, next exercise, round count, halfway, ten seconds, and workout complete without looking at the screen.

Warm-up, cooldown, transitions

Session Cards

Offline local workouts

Session Cards
A workout your audience can save and run.
Turn a saved workout into a downloadable card with a Session Code. Share the image anywhere. Another user opens Kairox, imports with the code, and saves a cloned copy into their own library.
Session Cards are a V1 sharing tool, not a social network or marketplace.

Once Kairox has been opened on your device, saved local workouts can be available offline. You can build and run local workouts without relying on cloud sync.
Cloud features such as sync, billing, support, Session Card creation, and Session Code import need internet.
Kairox works best while the app is open and does not currently promise locked-phone or background execution.

Kairox vs traditional interval timer apps
Traditional interval timers are useful when all you need is work/rest timing. Kairox is built for people who want the whole workout to run like a session — exercises, rounds, rests, reps, sides, transitions, and shareable Session Cards.
| Capability | Traditional interval timers | Kairox |
|---|---|---|
| Session model | Basic work/rest intervals | Full workout-session flow |
| Guidance | Timer labels on screen | Voice-guided session cues |
| Structure | Generic rounds | Exercises, reps, sides, warm-up, cooldown, transitions |
| Sharing | Private timers | Shareable Session Cards with Session Codes |
| Connectivity | Cloud-first assumptions | Local saved workouts that run offline after loading |
What Kairox is not

- Not a form-coaching app.
- Not medical advice.
- Not a replacement for a qualified trainer.
- Not a nutrition tracker.
- Not a social network.
- Not a promise of locked-phone or background execution.
