KAI: Gym & HIIT Tracker
Workout planner & lifting log
Free · In-App Purchases · Designed for iPad
Gym and HIIT in one app, with an exercise catalog that keeps growing. Track your sets, let the circuits run themselves, and build your consistency.
Fitness that fits your life — not the other way around.
KAI brings gym and HIIT together in one calm, focused app. Whether you have ten minutes or a full hour, on the mat at home, at the gym, or outdoors, you have what you need to train well and keep going. No shouting, no "no excuses". Just a system that makes consistency easy.
CHOOSE YOUR PATH
Want to be guided? Open ready-made workouts across high-intensity cardio, strength, endurance, and low-impact sessions. Each one is structured to make the most of the time you have.
Already know what you want? Be your own coach. Build custom gym routines, choosing exercises, sets, reps, and rest, or design timed HIIT circuits. Save them, track your progress, and adjust everything around your real goals.
SMART TOOLS, RIGHT IN YOUR SESSION
While you train in the gym, KAI works out the numbers for you:
- Estimated 1RM from any set.
- Ready-made warm-up ramps based on your working weight.
- RPE / RIR to %1RM, turning effort into the right load.
WHY IT WORKS
- Short, well-built workouts: real substance, in the time you have.
- Total flexibility: home, gym, or outdoors.
- For every level: from your first session to years in.
- You're in control: follow a plan or create your own.
KAI is built on a simple idea: systems beat willpower, and continuity beats perfection. It's fitness that works inside your life, not over it.
Consistency, not perfection. That's KAI.

Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
The exercise catalog keeps growing: plenty of new movements to choose from when you build a plan or a circuit.
We've refreshed the overview of your training and made it easier to find the workouts you come back to most.
The rest is visual polish and under-the-hood improvements, to keep KAI smooth session after session.
Thanks for training with KAI.
