Log a set in two taps
From your wrist: tap the set, tap done. The phone holds the plan, the history, and every PR. Classic strength progressions, hybrid-race prep, and conditioning blocks come included.
Acta Fit
Your data. Your AI. Your gains. A lifting and conditioning log for iPhone and Apple Watch, two taps from your wrist. Then talk through your plan with Claude or ChatGPT, the AI you already trust. Now in private alpha.
You're on the record.
When your batch opens, we'll send a TestFlight invite to this address. Sign in inside the app with the same email and your alpha access follows you.
Bring the AI you trust
Connect Claude, ChatGPT, or any MCP-compatible client to your training history. No coaching subscription. The AI you already use becomes the one that knows your training.
Talk to AI about your plan
Through MCP, your AI sees your history, training maxes, and current plan. Ask why a lift stalled, get next week's block drafted, or rebuild the plan around a race. You review before anything lands.
