Start tracking the second you open it. No routines to build. No endless exercise picker to scroll through. No grid of buttons, sliders, and +/āˆ’ controls that looks like a jet dashboard. Just type or say what you did - "3Ɨ10 bench at 135" - and it's logged, grouped into the right workout, and plotted on your progress chart before you're back at the rack. —— WHY CNTR 01 / NATURAL LANGUAGE Plain English in. Structured data out. Type or dictate the way you'd tell a friend. CNTR AI parses sets, reps, weight, and exercise name automatically. Example: "3Ɨ10 bench at 135" → Logged Ā· Bench Press Ā· 135 Ɨ 10 Ɨ 3 02 / NO GYM-SPEAK Don't know the name? Just describe it. "That cable pull-down thing." "The leg machine you sit on." CNTR understands what you mean. 03 / SMART FOLLOW-UPS Forgot a detail? It asks. Missing weight, reps, or sets? CNTR asks one short question instead of failing or logging bad data. 04 / EQUIPMENT MEMORY It remembers your machine setup. Tell it your seat height, pad position, or grip once. Ask any time after - it'll tell you exactly what you used. 05 / PROGRESS, AUTOMATIC Every exercise is captured and grouped into workouts along with comprehensive progress charts . —— HOW IT WORKS Open the app between sets. No login, no setup, no daily routine to load. The keyboard is already up. Type or speak what you did. "3Ɨ10 bench at 135." "That leg curl machine, 4 sets of 12 at 70." Whatever's faster. That's it. It's logged. Sets, reps, weight, and exercise name are saved and charted. Walk back to the rack. —— WHAT'S INCLUDED • Workout logging in plain language • AI that asks smart follow-up questions when details are missing • Full structured workout history • Progress charts for every exercise • Equipment settings memory - seat heights, pad positions, grips • No account, no email, no signup
