BarbellMax 1.1 — collars now count, units convert, and your rest timer finally keeps time in the background. Tired of doing math between heavy sets? Stop calculating in your head while exhausted. BarbellCalc is the cleanest, fastest, and most precise barbell plate and 1RM calculator designed specifically for powerlifters, weightlifters, and gym enthusiasts. FEATURES YOU'LL LOVE: 1. VISUAL BARBELL LOADING • Instant visual representation of your barbell with official IWF color-coded plates. • Accurate breakdown of exactly what plates to load on each side. • Tap any number to type your custom target weight directly. 2. DYNAMIC ISLAND & LIVE ACTIVITIES • Pin your current working weight to your Lock Screen or Dynamic Island. • Glance at your phone on the gym floor without unlocking it. 3. 1RM & TRAINING PERCENTAGES • Calculate your true One Rep Max using industry-standard Epley and Brzycki formulas. • Instant training percentage table (50% to 95%) with one-tap loading back to the bar. 4. AUTOMATIC WARM-UP LADDER • Smart progressive warm-up sets generated automatically from empty bar to your work set. • Interactive checkmarks and integrated rest timer. 5. CUSTOM GYM INVENTORY • Supports both LBS and KGS. • Toggle off plates your gym doesn't have (like 35 lb plates or micro fractional plates). • Choose from Standard Olympic bars (45lb/20kg), Women's bars (35lb/15kg), Trap bars (55lb), or custom bar weights. ZERO ADS. ZERO SUBSCRIPTIONS. ZERO CLUTTER. Pay once, own forever. Build for the lifter, by a lifter.

Thanks for training with BarbellMax! This update is all about getting the numbers right and keeping you in the flow between sets. WHAT'S FIXED • Collars are now counted properly. Turn on Collars and the per-side weight, the plate list and the barbell view all agree — load the bar and the math matches. • Smarter plate loading. If you've turned off plates your gym doesn't have, the app now finds the exact plate combination when one exists, instead of telling you the closest match was short. • Switching units converts your weights. Going from lbs to kg (or back) converts your target and bar weight automatically, so you never end up with a target of "225 kg" or a 45 kg bar. • A rest timer you can trust. Your rest keeps counting accurately when you switch tabs or leave the app — and if you've pinned the Live Activity, the countdown now shows up on your Lock Screen and in the Dynamic Island. • Cleaner warm-up ladder. Light days no longer repeat the same weight five times in a row, and checkmarks reset when you change your working weight. • More realistic 1RM estimates. High-rep estimates no longer jump to unrealistic numbers, and the app tells you when an estimate is only a rough guide. SMALLER FIXES • Entering a weight keeps your decimals, and tells you when a value can't be used. • The bar no longer says "closest match" when your target is lighter than the bar itself. • Plate graphics no longer flash every time you tap +5. • The Pin button for Live Activities works reliably, and explains itself if Live Activities are turned off in Settings. • Standard bar weights match up correctly in both lbs and kg. • Removed a leftover placeholder widget from the widget gallery. Keep lifting. — BarbellMax
