KAI: Gym & HIIT Tracker

Two ways to train, one app. Track every gym set, let HIIT run itself, and build a routine that fits your real life.

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.
