locknn: Gym Workout Tracker, Workout Log and AI Coach

Train, log it, and let your AI coach take it from there.

LOCKNN is a gym workout tracker and workout log built for progressive overload: every set, rep and weight saved, with volume trends and personal bests. It is a step counter and run tracker too, with live calories, heart rate, distance and pace. Pick from 50+ workout types, tap start, and go.

YOUR AI COACH

+++ +++ +++ +++ +++ +++

Ask your AI fitness coach anything, any time. It reads your real training history, so the answers are about you: what to train next, why a lift stalled, how to rebuild after a week off, whether today should be heavy or easy. Run a body scan to see where you are now, then check back in as it changes. Your AI coach and body scan both answer in your own language.

HOW IT WORKS

+++ +++ +++ +++ +++ +++

Choose your workout from running, strength training, cycling, swimming, HIIT, yoga, boxing, hiking, rowing, and dozens more. LOCKNN tracks the session live with elapsed time, calories burned, heart rate, and GPS-based distance for outdoor activities. When you finish, your workout log is saved in full detail: pace splits, elevation changes, average and peak heart rate, and total calories.
