Stop doing plate math between sets. Type the weight you want on the bar and Rack Math shows exactly which plates to load per side, based on your plates, your bar, and your gym. Build a list of weights, and it tells you precisely what to ADD and REMOVE to get from each set to the next, so you spend your rest resting. FREE, FOREVER • Instant plate math for any weight, in lb or kg • Your plate inventory: only weights you can actually make • Bar diagrams that match what’s on the bar • Build-on-bar: enter what’s loaded right now and work from there RACK MATH COACH Turn the calculator into a training partner. Try the Coach free for your first 10 workouts. No account. Nothing to cancel. Keep it with a subscription or a one-time Lifetime purchase. • A daily plan built around your lifts: Rack Math schedules what to train next and adapts as you recover • Freshest: an extra generated session for off days. Lifts picked from whatever your recovery says is most rested, with the day’s plan built around them • Cardio-aware recovery: with Apple Health, your runs, rides, and swims count toward what’s fresh, tracked as one total across activities, so swapping a walk for a run never reads as slacking • Unlimited weights in your stack • Warmup ramps in one tap: straight sets, top set + backoff, or 5/3/1 • Follow mode: the current set lights up, DONE advances, the next plate change is always right in front of you • Lock Screen Live Activity: your rest countdown, next set, and exact plate change. Log your set, skip rest, or load the next exercise without unlocking your phone • Apple Watch: follow along from your wrist with displays for weight, per-side plates, a rest timer that taps you when it’s up, and one-tap DONE, synced from your iPhone • Automatic progression: Rack Math suggests your next weights and reps • Strength tracking: your estimated 1-rep max over time, and personal records • Gyms: save plate setups for home, work, or travel and switch in two taps • Workout timer with per-exercise split times • Apple Health: finished workouts logged as strength training (optional) • Workout history: what you lifted, how long it took, your top weight, and the ability to reload any past stack onto the bar • Fewer-swaps optimizer: re-arranges the whole workout’s plate layouts to minimize how many plates you touch • Save and reload your stacks Choose your plan: Monthly, Annual (best value), or pay once for Lifetime. The plate calculator stays free either way. No ads. PRIVATE BY DESIGN Rack Math has no accounts and no ads. Your training lives on your device and, if you use iCloud, syncs privately through your own iCloud account; we never see it. We use one privacy-first analytics tool that collects no personal data and can’t identify you. Writing to Apple Health is entirely opt-in.
