Load the bar with the plates your gym actually has.
Built for mixed kilogram and pound gyms, garage gyms, CrossFit boxes, and lifters who are tired of guessing.
- Mixed kg and lb inventories
- Visual plate loading
- Closest achievable weight
- Works entirely on-device
Your gym, once
Enter the rack you actually have.
Counts are individual plates, not pairs — four 20 kg bumpers is four. Pick your bars, add anything off the standard list with Add a custom plate or Add a custom bar, and it is saved for next time.
- Kilogram, pound or mixed inventories
- Custom plates and custom bars
- As many gyms as you train at
Both units
A converter, for everything else.
Programmes written in one unit, plates stamped in the other. The conversion is shown with the arithmetic beside it, plus a reference table of the weights that actually come up in a gym.
- Kilograms to pounds and back
- The working shown, not just the answer
- Reference table for common plate weights
Why it exists
Most plate calculators assume a perfect set.
Real gyms have four 45s, a stray 12.5 kg bumper, and a bar measured in the other unit. Barbell Genie works from what is on your rack, not from an imaginary complete rack.
Mixed kilogram and pound plates
A 20 kg bar with 45 lb plates is normal in a CrossFit gym and awkward to do in your head. Enter both units, get one correct total, and read it in whichever unit you think in.
The nearest weight you can actually build
Ask for 205 lb and, if nothing lands on it, you get the closest load under and over, how far each one misses, and which plates would close the gap. Not a wrong answer presented confidently.

No account, no sign-in, no network. It works in a basement with no reception because it never needed a connection in the first place. Nothing about your training leaves the phone — and nothing can.
