Train Libre is a private, open-source workout and nutrition tracker for people who want serious logging without giving up control of their data. It is offline-first: no account, no social feeds, no gamification, no ads, and no commercial tracking or data selling.
Track your workouts, calories, bodyweight, and muscle recovery in one focused app, with secure local storage and optional Apple Health integration.
WHY TRAIN LIBRE IS DIFFERENT:
• Offline-First: No account and no network connection required. Your training and nutrition data stays in your device's sandbox.
• Privacy by Design: No ads, no ad trackers, no session recording, no user profiles. Usage statistics are optional and off by default — they never contain health data or your IP address, and you can turn them off and request erasure at any time.
• Structured Gym Tracking: Built for progressive overload and rigorous logging, not addictive engagement hooks.
• Transparent Analytics: Understand your long-term physical trends through clear, math-based insights.
KEY FEATURES:
1. ADVANCED WORKOUT LOGGING
• Log workouts set by set, including warm-ups, working sets, failure sets, and dropsets.
• Track precise metrics: reps, weight, and RPE / RIR (Rate of Perceived Exertion / Reps in Reserve).
• Build reusable routines, add custom exercises, and review your full session history.
• Attach up to 4 photos to any session, taken with the camera or picked from your library, and keep them in your backups.
2. SCIENCE-BASED NUTRITION & TDEE
• Log meals, calories, macronutrients, hydration, caffeine, creatine, and custom supplements.
• Adaptive Energy Expenditure Engine: a Kalman filter-based Bayesian TDEE estimator calculates your true maintenance calories dynamically from your actual scale weight and nutrition data.
3. PHYSICAL RECOVERY TRACKING
• Visual Recovery Heatmap: monitor muscle readiness based on localized volume, training effort, and recent load.
• Comprehensive stats for PRs, total training volume, consistency, body measurements, and physical vitals.
4. NATIVE HEALTH SYNC
• Optional integration to read physical metrics (steps, sleep, pulse) and feed them into your local recovery tracking.
• Completely local, secure, and user-controlled.
5. BYOK AI MEAL CAPTURE (Optional)
• Bring Your Own Key (BYOK): optional AI meal recognition that runs on your own API key. Disabled by default.
• Photo, Barcode and Voice in One View: photograph your plate, let the same screen pick up the barcode of a packaged product, or simply describe the meal by voice. On iPhone models with LiDAR, depth scale is captured to assist portion estimation.
• State-Aware Matching: a local "Top-N Fuzzy Alternatives" system uses Open Food Facts to find plausible matches while keeping every result reviewable before saving.
• 100% Transparent: every AI suggestion is fully reviewable and adjustable before saving.
DISCLAIMER:
Train Libre is not a medical application. Algorithmic recovery feedback, sleep tracking, and physical vital metrics are intended strictly for personal athletic tracking and training guidance. They do not constitute, and must not replace, professional medical diagnosis or treatment.
