Acta Fit
Smart training for iPhone and Apple Watch
Lifts, race stations and runs in one log. During a workout your iPhone and Apple Watch share one live workout: sets, rest and edits pass between them.
Bring your own coach. Acta Fit has no built-in AI; it keeps every set, split and station in a form any MCP-capable assistant can read, such as Claude or ChatGPT where supported, so the AI you already use can help build your next block.
