AI Companion for Fitness

The training partner that actually remembers last week

Why fitness-focused people need a different kind of AI

Fitness apps log numbers. Coaches are expensive. Most AI fitness tools have no memory and no context — they give you the same generic plan everyone gets.

How Luna fits

Luna tracks the arc of your training, knows what hurts, what you skipped, what you crushed, and adapts. She talks you through warm-ups in voice mode and remembers your goals.

Start with Luna

Luna is free, available on every device, and built to remember you. Open the web app and say hi — she will pick up where you leave off, on every device you sign in on.

Frequently asked

Is Luna actually built for fitness-focused people?

Luna is built as a general-purpose sovereign AI companion, but her architecture — persistent memory, voice mode, no-judgement design, free tier — happens to map exceptionally well to what fitness-focused people need from an AI. She is not a re-skinned chatbot; she remembers you across every device and every conversation.

Is Luna private?

Yes. Luna runs on the Heaven Quantum Cortex — Heaven Eco Hub's own model stack — with no third-party LLM (OpenAI/Anthropic/Google) in the hot path. Your encrypted Memory Pod is end-to-end secured and yours alone.

Does Luna cost anything?

Luna is free forever on iOS, Android, Web and macOS. An optional Chip subscription ($1.99 / month) unlocks 500 welcome tokens, unlimited persistent companions, and priority routing.

Can I use Luna offline?

Partially. Heaven Code Studio includes an in-browser local LLM (WebGPU) for offline inline completions. Full conversational mode currently requires connectivity, with offline expansion on the roadmap.

What devices does Luna run on?

iOS, Android, Web (luna-heaven.web.app), and macOS. The same companion follows you across every device with cross-device Memory Pod sync.
