Why the app?
The web calculators are fine for occasional use. The app is what you want in the gym: one tap from your home screen, works offline, and remembers your unit preference. All five calculators are free, and they run the same math you just used on this page.
There's a $1.99 one-time upgrade if you want it to remember your own plates — the exact sizes your gym stocks, custom colours, and the odd ones (55 lb, 1.25 lb, specialty bars) — so the loader only offers you weights you can actually make. One purchase, no subscription.
