EatFastTrain Complete Fitness
One app for nutrition, intermittent fasting, strength training and weight. A personal health OS that actually understands the whole picture.
The four pillars
Most health apps solve for one thing: MyFitnessPal does nutrition, Zero does fasting, Strong does workouts, Happy Scale does weight. Each is great at its job. Each lives in its own silo. EatFastTrain unifies all four — with shared data feeding a coach that can actually reason across them.
Eat
Diary, barcode scan, AI photo recognition, meal ideas, recipes.
Fast
Active fast timer, protocols, auto-start schedules, streaks, Live Activity.
Train
Set-by-set workout logger, rest timer, PRs, progression charts.
Weigh
Weight logging, velocity tracking, BMI, goal projections.
Features worth calling out
AI Coach free
Chat-based personal trainer with full context on your macros, fasts, workouts and weight. Not a generic LLM — it reads your actual metrics before answering.
Photo-to-nutrition pro
Point your camera at a meal, get macros. Scan a nutrition label, get structured data. Describe a meal in words, AI estimates and lets you refine.
Meal Idea Generator pro
Give it a macro target, constraints and preferences. Get a recipe with step-by-step cooking mode and a categorised shopping list.
Weekly AI Insights pro
Auto-generated weekly report covering all four pillars. Not a dashboard you pull — a briefing that shows up.
Apple Watch + Widgets free
Native watchOS companion, 5 home screen widgets, Live Activities for fasts and workouts. Deep iOS integration, not a retrofit.
Diary sharing free
Share your daily food log with one other person (partner, coach, accountability buddy). The only social feature, on purpose.
