Prism: AI Gym & Workout Coach
Personal Trainer & Lifting Log
Free · Designed for iPhone. Not verified for macOS.
Track your lifts, read your recovery, and let AI build a strength training program that evolves as you improve. Prism is the workout coach that adapts to how your body actually feels, not just what's written on a plan.
TRAINING READINESS: KNOW BEFORE YOU GO
Most gym apps log what happened. Prism tells you what to do next. Using your Apple Health data, Prism calculates a daily Training Readiness score so you know whether to push hard, train light, or rest before you even leave home.
YOUR AI PERSONAL TRAINER
Generic workout plans don't account for your schedule, your recovery, or how you're actually progressing. Prism's AI analyses your workout history, recovery trends, and goals to generate custom training programs built specifically for you.
Progressive overload calculated automatically, no spreadsheets needed
Volume and intensity adjust based on your actual progress
Works for strength training, muscle building, and general fitness
Programs adapt when life, travel, or soreness gets in the way

Log every set, rep, and weight in seconds. Prism auto-fills suggestions from your history so you spend less time on your phone and more time lifting.
Full exercise library with detailed movement tracking
Personal record detection with instant celebration

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Your AI coach just got a lot smarter. Responses are now faster and more conversational, so coaching feels less like a chatbot and more like a real back-and-forth.
Training Readiness has been overhauled with better accuracy, so your daily score more reliably reflects how your body is actually recovering.
