Kairos: Workout Tracker

Your workouts, your data, yours forever. One purchase — no subscription, no ads, no account. Log fast, train with Coach Mode, and watch every PR climb.

Kairos is the strength and gym tracker for people who just want to train — not manage a subscription.

One purchase. Yours forever. No subscription, no ads, no account, no cloud. Everything lives on your device.

COACH MODE — YOUR VOICE-GUIDED SESSION Press start and train. Coach Mode walks you through every set and rest, block by block, with a live timer and automatic rest countdowns — so your eyes stay on the bar, not the screen.

LOG FAST, MISS NOTHING Tap in weight and reps in seconds. Full workout history, forever, with no limits on what you can look back on.

SEE YOURSELF GET STRONGER Every personal record is celebrated the moment you hit it. Track trends, volume, and progress across your whole training history.

REAL PROGRAMS, READY TO GO Start with structured Push/Pull/Legs and full-body plans, or build your own. 650+ built-in exercises with clear animated demonstrations and muscle-activation maps.

SHARE THE WIN Turn any finished session into a clean, shareable card — your volume, your exercises, your PRs.

BUILT FOR COACHES Build programs and hand them to clients as a single file. Your athletes import and train — no accounts, no platform in the middle.
