15-minute daily pair programming challenges that feel like lifting a dumbbell — progressively harder, immediately rewarding.
Like a chameleon, our AI adapts each session to your exact skill level. Like a boomerang, our algorithm reconnects you with the same partners, turning strangers into mentors. Like durian — intimidating at first, oddly addictive once you're in.
Start Your First Kata →You complete your first 15-minute session having actually built something working, and the app immediately shows:
"Your pair from yesterday just leveled up and wants to catapult with you again — ready for challenge #47?"
You click yes, and suddenly you're coding with someone who's exactly one step ahead of you, explaining concepts in real-time as you build together.
