Workouts

😴

Sleep Science

Not just hours — sleep stages, HRV, heart rate and respiration, chronotype, sleep-debt history and an energy schedule that tells you when you actually peak.

⏱️

Fasting & Check-ins

A fasting timer with metabolic zones, mood meter, water tracking with custom containers, weight and body measurements, plus any custom category you invent.

Reports & Trends

20+ chart types: macro trends, muscle recovery, workout heatmaps, sleep consistency, body battery, period summaries. Your long game, visualised.

Family Profiles

Multiple users with permission-based access. Coach a partner or track the kids' nutrition — each profile separate, shareable only when you choose.

An AI coach that logs

Meet the built-in assistant. It doesn't just chat — it has hands on your diary. Snap a photo of your plate and it estimates portions, breaks down macros and logs the meal. Ask for trends and it reads your last 30 days.

  • Photo → macros. Food image analysis with per-item grams, calories and confidence levels.
  • Label scanner. Point it at any nutrition label and it extracts the facts.
  • Real coaching. Health summaries, pattern detection and auto-generated macro plans from your actual data.
  • Your AI, your key. Works with OpenAI, Anthropic, Gemini, Mistral, Groq, OpenRouter — or fully offline with local Ollama. Keys stored encrypted.
