PrismCoach is an AI-assisted strength and recovery coach for iPhone, iPad, and Apple Watch. It reads your Apple HealthKit data — HRV, resting heart rate, sleep, and active calories — and uses a Muscle Battery system to track the recovery state of every muscle group in your body. PrismCoach is not medical advice. Consult a physician before starting any exercise program. AI-generated recommendations may be inaccurate. INTELLIGENT MUSCLE RECOVERY Tap any muscle on the interactive 3D anatomy model to see its recovery status. PrismCoach tracks 33 muscle groups individually, estimating fatigue from your workout history and recovery from your biometrics. Green means ready to train, yellow means proceed with caution, red means rest. AI COACH THAT KNOWS YOUR BODY Ask the built-in AI coach anything about your training. It sees your full recovery state, nutrition intake, and readiness score before answering — so every recommendation is grounded in your real data, not generic advice. Supports voice input and text-to-speech for hands-free interaction during workouts. AI responses are generated by language models and may be inaccurate — always verify with a qualified professional. BODY BATTERY & READINESS SCORE A single 0–100 score tells you how ready you are to train today. The Body Battery synthesizes HRV, resting heart rate, sleep quality, and cumulative training stress into one clear number. Requires Apple Watch and HealthKit connection for measured data. 12 PROVEN TRAINING PROGRAMS Browse curated programs including Starting Strength, StrongLifts 5×5, GZCLP, 5/3/1 Boring But Big, PHUL, Reddit PPL, Bodyweight Basics, Upper/Lower Split, nSuns 5/3/1 LP, Arnold Split, Power Building, and Full Body 3x/Week. Each includes structured sets, reps, rest periods, and progression schemes. 3 programs free; 9 require Pro. CAMERA BODY SCAN (Pro) Use your front camera for body pose detection — PrismCoach detects skeleton joint positions via Apple Vision framework to scale the 3D avatar to your body proportions. Equipment recognition sends a photo to a cloud AI for gym equipment classification. PRIVACY On-device AI processes most queries locally with no network. With cloud AI enabled, Pro users' queries and selected training context may be sent to Synalux servers and processed by Google Gemini; profile names, email addresses, and Apple IDs are excluded. When the user explicitly submits an Equipment Scan, that captured photo is also processed by Google Gemini. A first-run privacy choice allows on-device-only AI. Core tracking, built-in programs, and Body Battery features work offline.

Privacy Policy: https://synalux.ai/privacy Terms of Use: https://synalux.ai/terms ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | PrismCoach Pro Monthly | $9.99 | per month | | PrismCoach Pro Annual | $59.99 | per year | ## Version history (last 5 releases) ### 1.1.9 — 2026-08-18 This update makes on-device coaching more reliable: steadier voice sessions, smoother chat, and you can now remove a muscle from your injured list right from the chat. Your coach can also receive model improvements without waiting for an app update. ### 1.1.8 — 2026-08-15 Recovery you report in chat now sticks. Tell the coach a muscle feels better and you can clear its limitation — previously only the muscle setup screen could do that, so programs kept avoiding a muscle you had already recovered. Equipment recognition works again, and you can now upload a photo from your library instead of only using the camera. The coach no longer talks over you. Replies are spoken when you ask by voice or tap the speak button — not automatically — and the transcript no longer scrolls itself while you are reading. Better answers: when an on-device reply is unusable, the coach now asks a stronger model instead of showing it. ### 1.1.7 — 2026-07-27 v1.1.7 — Visible Program Editing and Reliability • A new Create or Customize entry is visible at the top of Training Programs • Review generated or library programs before starting • Revise a program with a follow-up prompt • Add, delete, and reorder exercises; edit sets, reps, rest, effort, and training mode • Select target muscles for custom exercises from the editor • Deterministic safety checks rerun after every AI or manual change • Clearing a Pain status now updates generation and animation muscle highlighting • Optional reviewed light work remains available for a Limited / Pain area • Ending an animated workout now tears down the scene safely • Pro access credentials now refresh after an App Store update without requiring reinstall • Crash and program-flow diagnostics are restored for faster support ### 1.1.6 — 2026-07-23 v1.1.6 — Safer, Editable AI Programs • Review, add, remove, and reorder exercises before starting an AI-generated program • Revise a generated program with a follow-up prompt • Add custom exercises and select their target muscles • Deterministic safety checks after every AI or manual program change • Optional light/rehabilitation work for a Limited or Pain area, with explicit review and in-workout warnings • Current injury and pain changes now supersede stale chat context • AI Coach opens at the newest response and stays current during speech playback • On-Device AI Only now also blocks equipment-photo uploads • More professional AI error and safety language • Corrected exercise animation muscle highlighting • Clearer recovery when the on-device model is unavailable and more reliable program generation ### 1.1.5 — 2026-07-22 v1.1.5 — Safer, Editable AI Programs • Review, add, remove, and reorder exercises before starting an AI-generated program • Revise a generated program with a follow-up prompt • Add custom exercises and select their target muscles • Deterministic safety checks after every AI or manual program change • Optional light/rehabilitation work for a Limited or Pain area, with explicit review and in-workout warnings • Current injury and pain changes now supersede stale chat context • AI Coach opens at the newest response and stays current during speech playback • On-Device AI Only now also blocks equipment-photo uploads • More professional AI error and safety language • Corrected exercise animation muscle highlighting • Clearer recovery when the on-device model is unavailable and more reliable program generation ## More apps by Synalux LLC - [Prism-AAC](https://appshunter.io/ios/app/prism-aac/id6764692277) - [Synalux POS](https://appshunter.io/ios/app/synalux-pos/id6777999853) - [Prism AAC Browser](https://appshunter.io/ios/app/prism-aac-browser/id6781468968) All apps by Synalux LLC: https://appshunter.io/developer/1895881089 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
