Krio is an AI-powered fitness tracker that builds personalized workout programs and adapts to your body every single day.
Tell Krio your goals, experience level, and available equipment. In seconds, the AI generates a complete training program from a library of 873+ exercises — with optional warmup and cooldown routines built in.
SMART DAILY RECOMMENDATIONS
Every time you open Krio, it knows exactly what you should train. The muscle fatigue algorithm analyzes your recent sessions, tracks recovery across every muscle group, and recommends the ideal workout for today — or tells you to rest when your body needs it.
REAL-TIME WORKOUT TRACKING
Log sets, reps, and weights as you train. Krio tracks your progress in real time with a clean interface designed for the gym floor. A global rest timer follows you between exercises so you never lose your place.
873+ EXERCISES WITH DETAILED GUIDES
Every exercise comes with step-by-step instructions, muscle activation data, and equipment requirements. Filter by muscle group, equipment, difficulty, or movement pattern to find exactly what you need.
MUSCLE RECOVERY MAP
See your entire body's recovery status at a glance. The visual muscle map shows which muscles are fresh and ready to train, and which ones need more time. Make smarter decisions about when and what to train.
AI WORKOUT GENERATION
Need a new program? Describe your goal, pick your equipment, and let the AI build it. Choose to include warmup stretches, cooldown routines, or both. Every generated workout uses real exercises with proper progressions.
APPLE HEALTH INTEGRATION
Connect Apple Health to bring all your workouts into one place. Krio reads your Apple Watch runs, walks, cycling, and more — then factors them into your daily recommendations. Your cardio counts.
PROGRESSIVE OVERLOAD BUILT IN
Krio suggests weights and reps based on your history. See your personal records, track volume over time, and keep pushing forward with data-driven progression.
WORKS OFFLINE
No internet? No problem. Krio works completely offline with local-first storage. Your workouts, programs, and history are always available. Everything syncs automatically when you're back online.
WEEKLY PLANNER
Assign workouts to specific days of the week. See your training schedule at a glance and build consistency with a structured weekly plan.
PROGRAMS THAT GROW WITH YOU
Build your own templates or let AI create them. Organize exercises with drag-and-drop, customize sets and reps, and save programs you can repeat and improve on.
