PlatePal: Barbell Calculator

New in 1.6: The Percentage calculator is now free. Copy or share a workout as text, a card, or a story from one export sheet — plus a prompt to start a fresh session.

No mental math. No second-guessing.

PlatePal tells you exactly which plates to put on each side of the bar to hit any weight — drawn to scale, in your plate colors, using only the plates you actually own.

LOAD (free) • Enter Weight — type a target and see the exact per-side plate breakdown instantly, with a to-scale barbell in competition plate colors. • Add Plates — build the bar by tapping plates and watch the running total. Perfect for working up by feel, or answering "what's already on the bar?" • One tab, one number: Enter Weight and Add Plates share a working weight — type on one, swipe to the other, and it's already there. • Step up or down by your increment, tap a recent weight, or enter a weight in the other unit — PlatePal converts it and offers the closest loads your plates can actually build. • When an exact load isn't possible, PlatePal shows the nearest loadable weight.

WORKOUT LIST (free) • Tap "Add to Workout" on the Load tab to log the weights you hit, grouped by lift. • Add reps, reorder your sets, and retag lifts as you go. • Copy the whole session to paste into your gym or notes app — or Share it as a branded image card (a compact card or a full-screen story) to Instagram, Messages, or your camera roll. • Kept separately for each gym profile, so your home-gym and travel-gym sessions never mix.

ASK SIRI (free) • "How do I load my barbell in PlatePal?" Siri asks your target weight, then reads back AND shows the exact plates per side — using your active gym profile's bar, plates, and units. • Say the weight in any unit ("225 pounds" or "100 kilograms"). If it differs from your profile's unit, PlatePal converts it and tells you. • Or "Show me how to load my barbell in PlatePal" to open straight to the Load screen at that weight.

PERCENTAGES (free) • Tap "%" on the Load tab for a table from 20% to 120%, mapped to your exact plates and built for percentage-based programming. Every row shows the nearest loadable weight. • The base weight is yours to edit and never overwrites what's on the bar.

PLATE INVENTORY (free) • Set how many of each plate you own, or mark them unlimited for gym mode. PlatePal only suggests loads you can actually build.

MULTIPLE GYMS & BARS (Pro) • Save a separate setup (plates, bars, and units) for every place you train. • Switch bars (Olympic, women's, trap, technique, or custom) per session without touching your profile.

PLATEPAL PRO • Multiple gym profiles, multiple barbells, custom plate colors, and custom app icons.

Whether you're a powerlifter chasing a percentage, a coach setting up a rack, or just tired of plate math mid-workout, PlatePal gets the right plates on the bar, every time.
