MVN Fitness tracks nutrition, workouts, sleep, hydration, fasting and body metrics — with an AI coach that logs meals from a photo. Every gram, rep and heartbeat stays on a server we control. No ads. No trackers. No data brokers.
Log breakfast to midnight snack against a deep food database with OpenFoodFacts lookup. Calories, full macros and 15+ micronutrients, custom meals, templates, allergen flags and CSV import.
40,000+ exercises via the Wger database. Build workout plans and presets, track sets, reps and progressive overload, replay past sessions, and see a body-map of what you've trained.
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.
A fasting timer with metabolic zones, mood meter, water tracking with custom containers, weight and body measurements, plus any custom category you invent.
20+ chart types: macro trends, muscle recovery, workout heatmaps, sleep consistency, body battery, period summaries. Your long game, visualised.
Multiple users with permission-based access. Coach a partner or track the kids' nutrition — each profile separate, shareable only when you choose.
Passkeys, magic links, TOTP & email MFA, OIDC single sign-on and API keys. Consumer polish, infrastructure-grade security.
Installable web app plus native iOS and Android apps, light/dark themes and 27 languages. CSV export and built-in backups — your data leaves whenever you want it to.
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.
Big fitness apps monetise your body. Your weight, your meals, your sleep — packaged and sold. MVN Fitness runs on our own UK server: open-source code, our PostgreSQL database, our rules. Delete means delete.
