Fast Barbell Plate Calculator

For anyone who loads a barbell and doesn’t want to think about math between sets. Type the weight you want. Barbell Calculator splits it across both sides and shows you the stack on a bar you can pinch and zoom. Quick to read at a glance—especially when the gym’s loud and you’re in a hurry. Free (no ads) Target weight → plate breakdown + bar preview. Pounds or kilograms. Haptics on or off. Uses a normal Olympic-style plate set so you’re not digging through settings before your first set. Pro (one-time, not a subscription) When your gym isn’t “textbook”: Stack mode — Add plates like you’re at the rack; total updates as you go. Your rack — Match the sizes and counts you actually have. Your bar — Not 20/45 kg? Set your empty-bar weight. Tap the bar — Easily remove weights; it recalculates the rest so you’re not starting over. If you just need “what goes on the bar for 275?” the free app has you covered. If you want the app to behave like your gym, Pro is the upgrade.
