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
Use the interactive 3D anatomy model to record pain and choose training areas. Red marks recorded pain; cyan, green and orange show normal, light and heavy training selections. Pain reports stay active until you explicitly resolve them. Recovery estimates use available workout and biometric data; missing measurements remain unknown.
AI COACH THAT KNOWS YOUR BODY
Ask the built-in AI coach anything about your training. It can use available recovery, nutrition and readiness context to personalize responses. Generated workouts use your confirmed equipment, training goals and comfortable movements. 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. All built-in programs are available without a subscription.
CAMERA BODY SCAN
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, 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.
