Tap the plates you see on each side and Platezy adds them up, bar included. No more squinting at a plate tree.

Gym Inventory
Tell Platezy how many pairs of each plate your gym has. When the 45s run out, it loads 35s and 25s instead of guessing.

Use the big gym keypad, or tap +5, +10, +25 deltas to build up a number one-handed.
The barbell redraws instantly with the plates for each side, heaviest closest to the collar.
Need warmups or percentages? Switch tabs. Same weight, same bar, no retyping.




You enter a target weight and Platezy shows exactly which plates go on each side of the bar, drawn on a barbell in real time. It also builds warmup ladders, a 50%–105% percentage table, and works backwards from plates you tap to the total weight.
Powerlifters, commercial-gym lifters, home and garage gym owners, and Olympic lifters who want to stop doing plate math between sets.
Yes. Set how many pairs of each plate you own and Platezy will never suggest one you don't have. You can also pick different bars and include collars.
Both. The default follows your region and you can switch any time. Plates use standard colour coding so they match what's on your bar.
