Kalk is a calculator you write in like a notes app. Type words and numbers together, the way you'd jot something down: "Rent 1 200 + utilities 180", "Coffee 4.50 × 20 workdays", "100 EUR in USD". Every line with a calculation shows its answer on the right, as you type. No keypad, no equals button, no lost history: the whole calculation stays readable and editable. WRITE THE WAY YOU THINK • Words around numbers are simply ignored, so notes and math share a line • Headings with #, comments with // • Big numbers the easy way: 1 250 000, 45k, 2.5M, 1bn • Decimal point or comma, whichever you're used to MATH, PERCENT, UNITS • Brackets, powers, negative numbers • Percentages the way people say them: 100 + 15%, 20% of 80, Price − 10% • Convert length, weight, volume, speed, temperature, time and data: 6 ft in cm, 180 lb in kg, 38 °C in °F CURRENCIES AND CRYPTO • Live exchange rates for world currencies • Bitcoin, Ethereum, Solana, stablecoins and more • Mix currencies in one line: £80 + €50, (0.1 BTC + 2 ETH) in USD TOTALS THAT ADD THEMSELVES • Write Total, sum or avg under a list to add it up • Sections end at a blank line or heading, so one sheet can hold many lists • The bottom bar keeps a running grand total • Name values and reuse them: Rate: $85, Rate × 37.5 ON ALL YOUR DEVICES • iPhone, iPad and Mac • Sheets sync through your own iCloud • Edit offline on several devices; Kalk merges the changes when they reconnect AND MORE • Lock private sheets with Face ID, Touch ID or your passcode • Share a sheet as text, PDF or image • Pin, sort and duplicate sheets • Dark, light or follow the system • Built-in cheatsheets with examples of everything Kalk understands Great for budgets, trip planning, splitting bills, invoices, renovation estimates, recipes, shopping lists, and any time you'd otherwise reach for a calculator and a notepad at once.
