Stay the same player in set three.

Tuko is a tennis fitness coach for busy players: about one hour a week, no gym, no partner, no court.

You can hang with anyone in the first set. Then fatigue hits: your first step gets late, your shots get rushed, and your game resets to factory settings. Tuko trains the part of the match you lose off the court.

Tennis, not generic fitness

• Tennis endurance. Intervals on the rhythm of real points, so you recover between rallies.
• Tennis reaction. Split-step on the cue, read the direction as you land, explode into the first step.
• Speed and change of direction. Sprint, brake, recover to the center, ready for the next ball.
• Tennis legs. Acceleration, braking, lateral push-off and jumps.

A coach in your pocket

Voice and beeps lead every session. After each one Tuko asks if you made it and adapts the next: the week repeats or you level up. Six weeks, one change at a time, built on sports-science research. No account, no ads, no tracking; it works offline.
