Train, log it, and let your AI coach take it from there. LOCKNN is the workout tracker that records the whole session, not just the numbers: every set, rep and weight, your live route and pace, the mood you were in, and the photo you took at the end. Pick from 50+ workout types, tap start, and go. Your AI coach +++ +++ +++ +++ +++ +++ Ask it anything, any time. The coach reads your actual training history, so the answers are about you: what to train next, why a lift stalled, how to build back after a week off, whether today should be heavy or easy. Run a body scan to get a read on where you are now, then check back in as it changes. How it works +++ +++ +++ +++ +++ +++ Choose your workout from running, strength, cycling, swimming, HIIT, yoga, boxing, and dozens more. LOCKNN tracks the session live with elapsed time, calories, heart rate, and GPS distance for outdoor activities. When you finish, it is saved in full: splits, elevation, average pace, and peak heart rate.

Your AI coach replies in your language too. Why LOCKNN? +++ +++ +++ +++ +++ +++ Most workout trackers are either too simple to be useful or too cluttered to enjoy.
