For ChatGPT, Claude and any MCP agent
Your assistant writes the program. Noostaa runs the session.
Plan in chat. Train from your iPhone and Apple Watch with the sets, loads and rest in front of you. Every set you log goes back, so next week’s numbers are earned, not guessed.

ExampleClaude, planning Thursday: “You finished every front squat set at RPE 7, so the load goes up 2.5 kg. Your left knee flagged on split squats, so this week is step-ups instead.”

How Noostaa fits into your training
Does Noostaa replace my AI assistant?
No. Your assistant still helps with the thinking: goals, progress, and what to train next. Noostaa is where the workout goes when it is time to move.
Which assistants does Noostaa work with?
Noostaa is built for workouts planned with ChatGPT, Claude, or your own AI assistant. It can connect through MCP where supported, or through the Noostaa CLI for custom agent workflows.
Which devices does Noostaa support?
Noostaa supports iPhone for following workouts and Apple Watch for workout recording.
Do I need a paid AI assistant?
It depends on the assistant you use and how much you use it. Some assistants may require a paid plan, higher usage limits, or access to tool connections such as MCP.
Does Noostaa replace my AI subscription?
No. Noostaa is a complement to your AI assistant. Your assistant subscription, limits, and billing stay separate from Noostaa.
Is Noostaa free?
Eligible new subscribers can start with a seven-day free trial. The subscription renews automatically at the local monthly price shown in the app unless you cancel before the trial ends.
Why not just keep the workout in chat?
Chat is great for planning. Training needs a dedicated flow: clear steps, rest timing, quick notes, and feedback you can leave before you forget how the session felt.
What does Noostaa remember?
The useful training signals: what you completed, what you skipped, how hard it felt, and what should change so your assistant can plan better next time.
Your next workout is one message away.
