The plate calculator built for people who actually lift.

Stop doing plate math in your head. Enter your target weight and Plate Calculator & PR Tracker shows you exactly which plates to load on each side of the barbell — in color, at scale, in under a second. IWF-standard Olympic plate colors (red 25 kg, blue 20 kg, yellow 15 kg, green 10 kg, white 5 kg) make the visual barbell instantly readable from across the rack. No grey blobs. No guessing.

Built for barbells, powerlifters, CrossFit athletes, and anyone who has ever done math on chalk.

--- FEATURES ---

Barbell Plate Calculator
The core tool. Dial in your target weight with the drum scroll wheel — designed for sweaty hands, no keyboard required. The app finds the closest achievable weight if your exact number is impossible with standard plates, and shows you the full plate breakdown per side.

Warmup Pyramid
One tap generates your full warmup ladder: 50%, 60%, 70%, 80%, and 90% of your target weight, each with its own plate layout. No more calculating five numbers before your first set.

PR Tracker
Log personal records by exercise with a date stamp. Your best lifts are stored on-device and never leave your phone. See your progress without managing a spreadsheet.

Benchmark Tracker
Compare your lifts to official strength standards across four levels: Beginner, Intermediate, Advanced, and Elite. Add your own custom benchmarks with separate RX weights for men and women — useful for CrossFit boxes and team coaches.

Interval Timer
Configurable rounds, work duration, and rest duration with audio cues. Screen wakelock keeps the display on between sets. Run it alongside the barbell plate calculator on the same screen.

Percentage Calculator
Quick percentage-of-max calculations for accessory work programming. Enter your max and get every common training percentage instantly.

Export & Import
Back up your PRs and benchmarks as CSV. Restore them after a phone swap. Your data stays yours.

--- DESIGN ---

Dark-first interface built for gym lighting. True black background (#0D0D0D) with electric lime accents — readable under any lighting condition. Proportional plate heights on the barbell visual mean a 25 kg plate looks bigger than a 5 kg plate, exactly as it does on the bar.

--- PRIVACY ---

No account. No sign-in. No cloud sync. No analytics. All data stays on your device. The app works fully offline — leave your Wi-Fi at home. One optional one-time purchase ($2.99) removes the bottom banner ad. No subscription. No recurring charges.

--- WHO IT IS FOR ---

Anyone who loads a barbell: powerlifters tracking a squat PR, Olympic lifters working up to a competition total, CrossFit athletes hitting benchmark WODs, or a gym member who just wants to stop doing arithmetic before every set. Supports both kg and lbs.
