Load the bar. Skip the math. Barbell.calc turns a target weight into an exact plate layout in kilograms and pounds at the same time. Built by a lifter, for the two minutes between sets when you shouldn't be doing arithmetic. TAP ON, HOLD OFF Tap a plate to add one per side. Press and hold to take one back off. The bar redraws as you go, with heavy plates seated against the sleeve and change plates drawn shorter — so you can read the load the way it'll actually look on the rack. REVERSE CALCULATOR Know the number, not the plates? Type your target and hit Calculate. You get the optimal loading instantly. If your plate set can't hit the number exactly, it tells you plainly and gives you the closest build instead of quietly rounding. PERCENTAGES OF YOUR MAX Enter a training max, drag the range to the percentages you're actually working in, and see the whole table. Tap any row and that weight loads straight onto the bar — no re-typing. TRUE KG AND LB SUPPORT Complete competition plate sets in both units. Kilograms: 25, 20, 15, 10, plus 5, 2.5, 2, 1.5, 1 and 0.5 change plates. Pounds: 55, 45, 35, 25, 15, 10, plus 5, 2.5, 1 and 0.5. The total displays in both units no matter which plates are on the bar. Switching units doesn't just convert the number — it rebuilds the same load out of the other plate set, as close as those plates allow. That's the honest answer, and it's the one you need when you train in kilos and your gym stocks pounds. MEN'S AND WOMEN'S BARS 20 kg / 15 kg, or 45 lb / 35 lb. Add 2.5 kg competition collars with one switch. YOUR GYM, YOUR PLATES Cross out any denomination your gym doesn't stock. Every calculation — forward, reverse, and percentage — respects your inventory. No more being told to load a 1.5 kg plate that doesn't exist in your rack. BUILT FOR THE GYM FLOOR - Works fully offline. No signal needed in the basement. - Haptic feedback you can turn off. - Large, glove-friendly targets. - A short tour on first launch, replayable any time from About. FREE, AND ACTUALLY FREE No account. No subscription. No in-app purchases. No ads. No analytics, no tracking, no data collection of any kind — everything you enter stays on your device. Made for Olympic weightlifting, powerlifting, CrossFit, and anyone who has ever stood at a loaded bar counting plates twice. Barbell.calc is an independent app by an NTR Barbell athlete, made with the gym's permission.
