Numline
A calculator you type into like a notepad.
Type a line, read the answer
Write "95 EUR * 4", "20% of 4800" or "rent = 2400" and the result appears on the right as you type. No buttons, no equals key. Change a number and every line below it updates.
Currencies and units
Convert between world currencies; rates update automatically, and offline the last known rates stand in. Length, mass, volume and temperature convert the same way: "120 km to miles", "356 F to C".
Variables and totals
Name a value once and reuse it: "rate = 85", then "32 * rate". Write "total" to sum the block above; a blank line starts a fresh one.
Dates, functions, notepads
"trip - today" and "trip + 2 weeks" work in place, and sqrt, round and abs are there when you need them. Keep a separate notepad for every plan. They stay on your device, with no account and no ads.
