Rechner is a minimal note-taking app that calculates as you type and shows inline results. It supports variables, units, syntax highlighting, error hints and a distraction-free interface.
// Simple calculation
5 + 2 / 4 - 2
5 ^ log_(2+3)(100)
3E100 / 4E62
// Dimensional analysis
5 m + 3 in
accel = 5 m/s^2
vel = (accel * 2 s) in km/h
(vel * 100 ms) in m
// Natural language
5 times 20 plus 2
10%. of 20 Work in Progress!
