Athletes pay nothing, ever. Coaches pay for the workspace — and the only thing that scales the price is the number of active athletes, never a wall of feature locks.
Create and log your own workouts, track history and progress, and join any coach or team by invite. No subscription. No card. No catch.
Solo coaches, personal trainers and small groups.
Growing coaches with larger rosters.
Teams, clubs and academies.
Custom athlete limits, dedicated onboarding, advanced permissions, priority support and possible integrations — built around how your organisation runs.
PRICING SCALES WITH ATHLETES IN YOUR WORKSPACE · ATHLETE APP IS ALWAYS FREE · FREE DURING BETA — PRICES SHOWN ARE FOR GENERAL AVAILABILITY
Yes — athletes create workouts, log training and track progress at no cost, with or without a coach. Forever.
Every athlete in your workspace roster — inviting an athlete uses one slot on your plan, whether or not they've trained yet. Removing an athlete frees the slot.
Kosoku is currently in a free, invite-only beta, so there's no billing to change yet. At general availability you'll be able to upgrade or downgrade as your roster grows or shrinks.
The monthly/yearly toggle above shows what workspace pricing will look like at general availability — yearly is planned at 20% cheaper than monthly. Nothing is billed during the free beta.
