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.

  4. 4

Core features

Workout Builder

Build sessions from your own exercise list with rounds, reps, sides, work/rest, warm-up, cooldown, and transitions.

Saved Workouts

Keep full workouts ready to run so you never have to rebuild the timer from scratch.

Preset Library

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.

Reps and sides

Set rep targets and left/right cues so structured work stays balanced.

Warm-up, cooldown, transitions

Every phase of the session is timed, not just the working sets.

History

Keep a clean record of completed sessions for review.

Kairox Sync and restore

Pro members can save workouts to their Kairox account and restore them on another device.

Session Cards

Turn a saved workout into a shareable card with a Session Code.

Import with Code

Open a Session Code in Kairox to clone a shared workout into your own library.

Offline local workouts

Once Kairox has been opened on your device, saved local workouts can run without internet.

Choose the workout format: your own work and rest times, or EMOM 60s slots.

Kairox Presets screen showing ready-made timer templates by category

Presets are ready-made timing templates you can adjust before training.

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.

Offline and local-first training

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.

What Kairox is not

Kairox helps run the session. It does not coach exercise form, provide medical advice, replace a qualified trainer, or promise that workouts keep running while your phone is locked or the app is backgrounded.

  • 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.
