RepForge is a private, on-device hypertrophy training system. Build a real mesocycle around your goal, your equipment, and your weak points — then log every set, every rest, every PR without typing a single word. Train smarter, not louder. **WHAT YOU GET — FREE** • Guided 8-step onboarding that builds a real periodized block from your goal, experience, frequency, split, and equipment • Push, pull, legs, upper, lower, full-body, and bro splits with sensible defaults — or skip onboarding and start with PPL • Mid-workout: log sets with one tap, swap equipment when a station is busy, see your full session in one place • Visual exercise library with full instructions, images, and muscle targeting • Workout history with the last 90 days included on the free tier • Body measurement tracking in inches or centimeters • Local backup export and restore • End-of-mesocycle review with deterministic next-block recommendations **WHAT YOU UNLOCK WITH PREMIUM** • Voice logging — say "two twenty five for eight" and the set is done • On-device AI session summaries (uses Apple Intelligence on iOS 26+) that explain how today's session compared to last time • Progress scoring across physique, strength, and training quality with weekly snapshots • Apple Health sync for sleep, resting heart rate, HRV, and body weight to drive daily readiness guidance • Camera-assisted weight scanning for plates and stack-pin machines • Guided physique check-ins with on-device pose analysis and visual comparison slider • Session-by-session deltas: every working set compared to your last attempt • All-time history beyond the 90-day free window • PR timeline + multi-lift strength dashboard Privacy Policy: https://lifedasa.com/repforge/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
