Numline: Calculator Notepad
The calculator you type into
$0.99 · Designed for iPad. Not verified for macOS.
Type a line, get an answer. Budgets, currencies, percentages and dates — worked out as you write, in a notepad that does the maths for you.
Numline is a calculator you type into like a notepad. Write your maths in plain words on the left, and answers appear instantly on the right.
No buttons to hunt for. No equals key. Just type a line — "120 USD to EUR", "20% of 4800", "rent = 2400" — and Numline works it out as you go.
WHAT YOU CAN DO
• Plain-language maths — write "95 EUR * 4" and read the answer beside it
• Currencies — convert between world currencies: "cost in JPY to USD". Rates update automatically; offline, the last ones stand in and results are approximate
• Units — length, mass, volume, temperature and more: "120 km to miles", "356 F to C"
• Percentages — tips, discounts and splits in words: "89 + 15%", "240 / 4 + 10%"
• Variables — name a value once and reuse it: "rate = 85", "32 * rate"
• Totals — "total" sums the block above; a blank line starts a fresh one
• Dates — "trip - today", "trip + 2 weeks" and other quick date maths
• Functions — sqrt, round, abs and friends when you need them
• Shorthand — "19k + 80k" reads thousands the way you say them
• Themes — Classic, Lime, Violet and Amber, each colouring your notation its own way
• Many notepads — keep a separate sheet for every plan
Every line is live. Change a number and everything below it updates. It reads back like a note you wrote to yourself, so you can always see how you reached an answer.
Numline stays quiet and focused: a dark editor, syntax colours you choose, and nothing in your way.
No account. No subscription. No ads. Your notepads stay on your device. Just type.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Reordering the home list is steadier near the screen edges. Picking up a notepad at the bottom no longer scrolls the list away; the list scrolls only when you move it towards an edge
• In Reorder mode, a long press keeps the notepad lifted instead of opening its menu
• A notepad's menu now needs a slightly longer hold, so starting a drag no longer opens it by accident
• The = key on Numline's pad now adds spaces around itself, just like + - x and /
