ChlngeAI

Your gym. Your rules. Challenge yourself to Change: ChlngeAI
chlnge is the AI-powered fitness app built for people who train with intention — strength athletes, CrossFit regulars, and gym lifers who want a smarter way to program, track, and compete.
ONE TAP TO TRAIN
Stop guessing what to do at the gym. chlnge AI generates a complete, personalized workout in seconds — built around your goals, your schedule, your equipment, and your body. Every session is connected to your history, your progress, and your limits.
CHAT TO ADAPT
Equipment taken? Short on time? Knee feeling off today? Talk to chlnge like a coach. Describe what you need and the workout updates instantly — no rebuilding from scratch, no compromising your program.
GYM-SPEED LOGGING
Log sets quickly. Track weight, reps, and RPE with a single tap. See your last performance for every exercise. Get notified when you hit a PR. Rest timers, substitutions, and smart defaults keep you moving between sets, not staring at your phone.
COMPETE WITH FRIENDS
Challenge a friend to the same workout and see who wins. Head-to-head challenges with fair scoring across total volume, strength metrics, and completion. Every challenge sent is a battle worth fighting.
SAFETY FIRST
Your injuries and limitations are locked into every workout. chlnge never recommends movements that contradict your constraints — and always offers alternatives when substitutions are needed.
