The calculator
you'll actually use
A powerful, programmable notepad calculator for your desktop. Type math like you think — with variables, units, and natural language.
Built for real work
Natural language math
Type like you think. "40% of $1,250" or "$85/hour × 2080 hours" just works.
Variables & references
Name your values. "rent = $2,400" then "rent × 12" on the next line. Change one, everything updates.
Unit conversions
Convert anything inline. "5.2 kg to lbs" or "340 km to miles" — no separate converter needed.
Running totals
Every line feeds into the next. Build up complex calculations line by line like a scratchpad.
Instant & lightweight
Opens in milliseconds. Lives in your menu bar. Cmd+Space and start typing.
Worth lookups
Connected to Oddworth’s database. Type "worth of a mass-produced lightsaber" and get a real answer.
