About this app

RepGenie is the gym calculator built for serious lifters. No subscriptions required to use the core tools — just open and calculate. PLATE CALCULATOR Enter a target weight and instantly see exactly which plates to load on each side of the bar. Supports lb and kg, all standard plate sizes, and custom bar weights. WEIGHT FROM PLATES Add up what's on the bar to see the total weight. Mirror mode ensures both sides match. 1RM ESTIMATOR Enter a weight and reps to estimate your one-rep max using Epley, Brzycki, or Lombardi formulas. Set a target rep count and intensity to get your working weight. WARMUP SETS Enter your working weight and get a complete warmup protocol with plate breakdowns for each set — tap any set to expand the plate diagram. REPGENIE PRO Unlock smart next-set recommendations that tell you whether to add weight, keep the same load, or back off based on your last set. Plus Gym Mode — a quick between-set adjuster that tracks your 1RM as you change reps and weight in real time. SETTINGS SYNC Sign in with a free account to sync your unit preference, bar weight, plate inventory, and machine presets across all your devices.

Baseline captured. Growth appears after the crawler observes a changed rating count.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
