## What is Sumline?

Sumline is a notepad that does the arithmetic as you type. Write a line in plain words and the answer appears in the margin — no equals sign, no calculator mode, no switching apps.

TYPE THE WAY YOU THINK
"3 rooms at 4.2m x 3.1m". "labour 3 days at $520/day". "$450 split 3 ways over 6 months". Sumline finds the sums inside your sentences instead of demanding you write an expression.

BUILT FOR A THUMB, NOT A MOUSE
A purpose-made key row sits above the keyboard with the operators, units and currencies this actually needs, and it changes with what you are typing. Press any answer and drag to change the number — every line below it recalculates as you move.

TOTALS A COLUMN YOU JUST TYPED
Write your costs down the page and put "total" underneath. Sumline knows what you meant. It will average or count them too.

DATES AND BUSINESS DAYS
"15 business days from today". "days until 30 Nov". "net 30 days from today". Weekends handled.

UNITS AND CURRENCIES
Metres to feet, kilos to pounds, litres to gallons. 40 currencies with rates you refresh when you want to — and everything keeps working offline with the rates you already have. Sumline tells you plainly how old they are.

NAMED VALUES THAT UPDATE EVERYTHING
Write "tile rate = $64 per m2" and use it anywhere below. Change it once and every line that depends on it follows.

NO DATA COLLECTED. NONE.
No account. No sign-in. No analytics, no crash reporting, no advertising. Your notes are encrypted on your device and never leave it, because there is no server for them to go to.

ONE PAYMENT
Free notes compute their first 30 lines. One payment unlocks every line in every note, for good. No subscription, ever.
