Forge is a workout tracker built around one principle: progressive overload that always works. Every set you log feeds a deterministic on-device engine that knows when to add weight, when to hold, and when to deload - automatically, every session, no AI required. Your workout works fully offline. Your data stays on your device - we don't see it. When the AI does help, it helps where it matters: building your starting program from your goals, equipment, and injuries. And every week, a quick check-in (fatigue, soreness, notes) adapts your upcoming week to how your body is actually responding. KEY FEATURES • Set-focus logging - one set at a time, large weight/rep inputs, background-safe rest timer • Deterministic progressive overload - double progression, rep progression for endurance ranges, automatic deload after 3 consecutive failures • AI program generation - onboarding asks 5 questions, generates a personalized week-by-week program • In-workout coach cards - AI explanations appear above set inputs when a weight increase is due (Pro) • Weekly check-in adaptation - AI modifies your upcoming week based on fatigue and soreness (Pro) • Progress tab - volume trends, estimated 1RMs, PR history, muscle-group heatmap, imbalance warnings • HealthKit integration - workouts written to your Apple Health on session complete; body-weight read used to scale starting weights and bodyweight-exercise volume • Streak tracking - visible chip on Home, no gamification clutter OFFLINE-FIRST Workout logging works with zero connectivity. AI is called only at three specific moments - onboarding program generation, session-start coach card pre-fetch, and weekly check-in submission - and never blocks a session. PRIVACY We don't collect your name, email, or location. Workout data stays on your device - v1.0 doesn't sync across devices. AI calls send anonymized workout snapshots to our backend; we don't sell or advertise on your data. Full details in our privacy policy. SUBSCRIPTION Forge is free to use for logging, progressive overload, streaks, and PR tracking. AI-powered features (program generation, coach cards, check-in adaptation, muscle heatmap, imbalance warnings) require Forge Pro at $9.99/month or $59.99/year.

AI suggestions are based on your inputs and general training principles, not on individual medical assessment. Consult a qualified healthcare professional before starting any new exercise program, especially if you have injuries or medical conditions. - Terms of Use (EULA): https://supiphat.github.io/forge-legal/terms.html Privacy Policy: https://supiphat.github.io/forge-legal/privacy.html ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Forge Pro Monthly | $9.99 | per month | | Forge Pro Annual | $59.99 | per year | ## Version history (last 1 release) ### 1.0 — 2026-05-28 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
