KruBoss
We've added more prep time options to our popular timer app : off, 10s, 15s, 30s — so you can strap on your gloves, breathe, and get locked in before the first bell.
Small tweak, big difference in your training flow.
Let’s work!

It’s fight week for us too!
Multiple updates are rolling out across the KruBoss ecosystem, tightening the experience everywhere.
This week:
• Bagwork: virtual boxing coach for your heavy‑bag sessions got fresh bug fixes and UI polish.
• Drills: our calisthenics training app received smoother transitions and stability tweaks.
• Timer: the interval boxing timer has been refined for cleaner rounds and better pacing.
• Sparta: the app to find a martial arts training partner around you has been fully reworked for a faster, smoother swipe experience.
Nak and Kru are already in the review pipeline and moving forward.
