Barbell Tools

Stop doing mental plate math between sets. Prepare exact barbell loads built around the specific plates in your rack. Barbell Tools helps you calculate achievable plate setups, generate warm-up progressions, estimate 1RM, and run training timers. It stays focused on the work before and between sets, without bloated trackers, subscriptions, or complex workout programs. PLATE LOADING FOR YOUR EQUIPMENT • Create custom rack profiles with your specific bars, collars, and plate inventory. • Enter a target weight to immediately see the exact or nearest achievable load. • View visual plate arrangements per side and step smoothly between load increments. • Save frequently used loads to reconstruct them instantly anywhere. WARM-UP PROGRESSIONS • Build structured warm-up sets that progress toward your working weight. • Automatically adapt percentage stages to match the physical plates you have on hand. • See exactly what plates to add or remove at each transition, with the ability to skip or repeat stages. 1RM & TRAINING MAX CALCULATIONS • Estimate 1RM from 2–10 reps using Epley, Brzycki, or Lombardi formulas. • Run guided multi-set tests to find your true working max safely. • Calculate percentage-based loads from 50% to 100%. • Send any calculated weight straight into the plate calculator with one tap. INTERVAL & REST TIMERS • Built-in Rest, Interval, and EMOM timers, including a quick Tabata preset. • Stay focused with haptics, custom audio cues, local notifications, and screen keep-awake mode. No accounts. No ads. No tracking. Optional tips support independent development without locking away any features.
