Knurl — Intelligent Strength Coach Train smarter. Get stronger. Knurl is the workout tracker built around a coaching engine that actually knows your training. Log your lifts, follow your program, and get coaching grounded in what you've actually done — not generic advice. A Coach With Your Real Numbers The coach sees every set, weight, and rep from your last seven sessions. Ask why you're stalling on bench, whether your volume is high enough, or what you should do next. It reasons from your history, not a template. Evidence-Based Programming Every response is built on proven training science — progressive overload, rep ranges by goal, RPE and RIR, volume guidelines, plateau diagnosis, and deload protocols. No fluff. Compete Against Real Lifters Four live leaderboards — Volume, Consistency, Cardio, and Strength — updated weekly. See exactly where you rank against every other Knurl user. Your row stays visible no matter how far down the pack you are. Gym Scanner Point your camera at the gym floor and Knurl builds a workout template from the equipment it sees. Traveling or at an unfamiliar gym? You're still covered. Full Workout Tracking Log sets, weights, and reps. Built-in rest timer with notifications. Template plan visible on every exercise card during your session so you always know what the program calls for. Post-workout summary with volume, duration, and any PRs you hit. Form Videos Built In Every exercise has a technique demo pulled from YouTube, Vimeo, Bodybuilding.com, or MuscleWiki. Tap Form on any exercise mid-workout to watch it. Progress That Makes Sense Track your estimated 1-rep max and max weight over time on a shared scale. Log bodyweight and see the trend. Personal records tracked automatically. Works Offline Log workouts anywhere, with or without a signal. Sets sync automatically when you reconnect.

It now reads clearly. • Knurl now reaches our servers on their own permanent address, so future infrastructure changes can never strand an installed copy of the app. ### 1.41 — 2026-08-28 - Starting-weight estimator rebuilt - "Today's game plan" — the pre-workout brief on the home screen - Garmin/FIT export that imports from an iPhone - Trial + Pro terms stated at signup, welcome card, trial countdown on Profile - Verify-email reminder - Progress tab is now Pro ### 1.40 — 2026-08-28 Introducing Knurl Pro Unlock unlimited AI coaching and the Compete leaderboard with a subscription. New accounts get a free 7-day trial of full AI coaching before Pro is required. Beta members are lifetime Pro subscribers, automatically — nothing to do, nothing changes for you. Also fixed: "Build with Coach" from the Templates tab wasn't actually sending your request — it now starts the conversation right away. ### 1.36 — 2026-08-17 • The coach is now always one tap away during a workout — no more losing track of the conversation between sets. • Aggressive and Volcano coaching styles are now available to beta and pro users. • Templates now support planning a target duration or distance — not just reps — for timed and distance-based exercises like planks, carries, and cardio. ### 1.35 — 2026-08-10 Coach recall: swipe away the mid-workout coach card and a small "Coach" button appears so you can bring back the exact same conversation later, even after checking another tab. Body composition tracking: log body fat %, muscle mass, bone mass, water %, visceral fat, and BMI alongside your weight on the Progress tab. Tap "Fill in from Apple Health" to auto-pull weight, body fat %, muscle mass, and BMI from a connected smart scale. Fixed a bug where switching tabs mid-workout could silently wipe a tagged gym location, your notes, or an in-progress coach conversation. All three now persist correctly. Fixed the coach card sometimes appearing blank until you scrolled the screen. Redesigned the Start Workout button for better readability in light mode. Added a floating Plates button so you can reopen the plate calculator mid-workout without scrolling back to the top. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
