# Forge: Adaptive Health Coach — Sleep, HRV, strength & burnout > Sleep, HRV, strength & burnout (iPhone/iPad app by ALEXANDER DAVID GRUINARD MACKENZIE.) - Source: https://appshunter.io/ios/app/forge-adaptive-health-coach/id6791003743 (this page in markdown: same URL + `.md`) - Developer: [ALEXANDER DAVID GRUINARD MACKENZIE](https://appshunter.io/developer/1886580061) - Category: Health & Fitness - Price: Free with in-app purchases - Age rating: 4+ - Requires: iOS 17.0 · 16 MB - Released: 2026-08-02 - Data updated: 2026-09-20 - User reviews in markdown: https://appshunter.io/ios/app/forge-adaptive-health-coach/id6791003743/reviews.md ## What is Forge? YOUR BODY, EXPLAINED AND ACTED ON Forge reads what Apple Health already knows — sleep, HRV, resting heart rate, wrist temperature, strain — and turns it into today's training, recovery, and wellness plan. Not another dashboard of numbers. One decision, with the reasoning shown. CATCH WHAT YOUR BODY IS TELLING YOU An Immune & Thermal Sentinel watches nocturnal wrist temperature against your own baseline and flags it before you feel it. An Autonomic Stress Barometer reads your nervous system in real time, with a guided 2-minute reset when it's running hot. A WORKOUT SHAPED BY TODAY, NOT A TEMPLATE See the full session before you begin — exercises in order, sets and rep ranges, target effort using RPE, rest times — adjusted for your recovery, sleep, energy, soreness, and equipment. Log weight, reps, and effort without leaving the live workout. PROOF, NOT A PROMISE Set a goal and watch a real trajectory: on track, drifting, or off track, with the reasoning shown — not a static plan. An empirical dose-response engine correlates what you actually log — supplements, sauna, alcohol, screens before bed — against your own next-day HRV and deep sleep, so you learn what moves your numbers instead of guessing. EVIDENCE-GRADED, NOT GENERIC Every supplement protocol and recommendation carries a graded citation — RCTs, clinical evidence, or preliminary — so you can see the strength of the evidence, not just a claim. START WITH A REAL BASELINE Your first session is intentionally conservative. Log the sets and effort you actually complete so Forge can use your real training — not invented scores — as the starting point for what comes next. IPHONE, APPLE WATCH, AND LIVE ACTIVITIES Move through your session from iPhone or Apple Watch. A Live Activity can keep workout status visible on the Lock Screen and Dynamic Island on supported devices. TRY THE COMPLETE LOOP FIRST The first three adaptive workouts are included. After that, Forge Pro unlocks unlimited adaptive workouts and the full recovery, nutrition, and longevity surface.
