PlateShift: Barbell Calculator

PlateShift is a free barbell plate calculator that thinks about your bar the way you actually load it.

Tell it what's on the bar right now and what you want next. PlateShift finds the fewest plates to pull and add to get there. It doesn't just give you what sums to your target, it gives you the cheapest path from where you are. No more math between sets.

• Fewest-plate-swap solver — the cheapest path from your current bar, not just any combo that sums to the target
• Choose your style: fewest plate swaps, or a balanced, even-looking stack
• Works in kg or lb
• Customize the plate set you have at your gym, including odd change plates
• Bumper-color visualization so the math matches what you see on the rack, with a Color-Safe palette for colorblind lifters
• Tells you when a target isn't reachable, and gives you the closest load that is
• Clean, distraction-free UI built for the 30 seconds you have between sets
• No accounts, no sign-in, no cloud sync. Your plate set lives on your device

Lift more, math less.
