Protokl

The only fitness app that forecasts your transformation using real science. See exactly when you'll hit your body goals — not just guess at them.

Protokl is not another static workout log or generic calorie counter. It is a bi-directional physiological engine designed to mathematically optimize your body composition and strength progression.

By replacing rudimentary step-functions and static algorithms with continuous mathematical curves and variance-adjusted modeling, Protokl adapts to your metabolism and recovery capacity in real-time.

Protokl is your all-in-one fitness transformation companion, built on exercise science to help you reach your body composition and strength goals faster.

SET YOUR GOALS Choose your path — fat loss, muscle gain, or body recomposition. Protokl builds a personalized plan based on your current stats, experience level, and preferred pace, then projects your timeline using our proprietary algorithm grounded in published physiological research.

DAILY PROTOCOL Your personalized daily checklist keeps you accountable. Track sleep, meals, workouts, body composition, steps, and custom tasks — all in one place. Smart reminders keep you on schedule, and tiles auto-complete as you hit your targets.

SMART WORKOUTS Recovery-based workout programming that adapts to you. Protokl tracks muscle recovery across 11 muscle groups, selects exercises based on your available equipment, and applies progressive overload automatically. Warm-up sets, supersets, drop sets, and rest timers are built in.

NUTRITION TRACKING Log meals from a curated recipe database or search thousands of foods. Protokl calculates your daily calorie and protein targets based on your TDEE, goal, and pace — then tracks your progress throughout the day.

BODY COMPOSITION ANALYTICS Track bodyweight, body fat percentage, and lean body mass with interactive charts. See your 2-week trend, plan forecast, confidence intervals, and goal progress. Syncs automatically with Apple Health.

STRENGTH TRACKING Monitor your lifts over time with per-exercise history charts, estimated 1RM tracking, and strength progression forecasts.

APPLE HEALTH INTEGRATION Seamlessly syncs with Apple Health to import steps, heart rate, sleep, VO2 max, and 60+ other health metrics. Your data stays on your device with automatic iCloud backup.

SCIENCE-BACKED PROJECTIONS Our forecast engine synthesizes research on muscle protein synthesis rates, fat oxidation limits, adaptive thermogenesis, and more to project your body composition journey with 90% confidence intervals.
