ForgeFox turns training, nutrition, recovery and personal health tracking into one clear plan for today. DAILY COMMAND Sleep, readiness, meals, training and your medication or supplement schedule continuously rebuild one next best action. Complete something, log a meal or dismiss a priority and the command adapts. TRAIN WITH A REAL PLAN • Follow adaptive programs with a clear session blueprint, recovered-muscle view and weekly load. • Log sets quickly with RPE or reps in reserve, rest timing, supersets, progression cues and personal-record tracking. • Start with ForgeFox Live or hand the structured session to Apple Workout. • Review muscle balance, training rhythm, strength standards and plateaus. LOG LESS. KNOW MORE. • Track calories, protein, carbohydrates, fat, fibre and micronutrients. • Capture a meal from a photo, barcode, search or natural-language description, then review every result before saving. • See the exact target for your next meal and adaptive macro goals based on your own progress. RECOVERY YOU CAN USE Connect Apple Health if you choose. ForgeFox combines sleep, HRV, resting heart rate, activity and a quick check-in into a readable recovery number and training recommendation. FORGE INTELLIGENCE Ask questions grounded in your own logged evidence. ForgeFox keeps transparent operational memory—recent recovery direction, training rhythm, meal capture and adherence—so answers have context instead of starting over every time. Use supported Apple on-device intelligence or managed Forge Pro through an App Store subscription. YOUR WEEK, MADE USEFUL The ForgeFox Index brings six pillars into one readable score. Detailed interactive trends and ForgeFox Weekly show what moved, what held and the one thing to carry forward. MEDICATION & SUPPLEMENT TRACKING Organize existing medications and supplements, reminders, adherence history and supply. ForgeFox tracks the plan you already follow; it does not prescribe or design treatment. PRIVATE BY DESIGN No account is required. Your ForgeFox database stays on your device. Apple Health is optional. Cloud intelligence is opt-in and the app explains exactly what is sent before use. Export and restore your own data whenever you need to. ForgeFox provides educational information and personal tracking tools. It is not a medical device and does not provide medical advice, diagnosis or treatment. Consult a qualified professional for medical decisions. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
