CNTR
Read full descriptionHide full description
Start tracking the second you open it. No routines to build. No endless exercise picker to scroll through. No grid of buttons, sliders, and +/− controls that looks like a jet dashboard. Just type or say what you did - "3×10 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: "3×10 bench at 135" → Logged · Bench Press · 135 × 10 × 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. "3×10 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
