Calculo vs Pixel QR

Calculo is a smarter way to calculate. Instead of punching buttons, you type. Math, notes, and answers — all on one screen, in plain language. Now with AI built in. Type 100 USD to EUR and get today's live exchange rate. Type x = 5 and use x in every line that follows. Type 15 kg to lbs and convert instantly. Calculo reads what you write and evaluates it — line by line, as you type. WHAT YOU CAN DO Math that reads like writing Type expressions naturally — 2 + 3, sqrt(144), 2^10 — and see results appear instantly, right beside your text. Ask Calculo — your built-in AI Not sure how to write it? Just ask. Type a question in plain English — "20% tip on 84.50" or "how many grams in 3 cups of flour" — and Calculo works it out, right on the canvas. Smart autocomplete Calculo predicts what you're typing and finishes the line for you — units, currencies, functions, variable names. Accept the suggestion and keep moving. Unit conversion — 213 units Weight, length, temperature, volume, speed, data, duration, angles, and more. Just write 5 miles to km or 98.6°F to celsius. Units combine and cancel, too — write 9.81 m/s^2 * 70 kg and get the force in newtons. Real-time currency conversion 180+ currencies with live rates. Convert with symbols, names, or ISO codes — $500 to ¥, 420 EUR to GBP, or 100 rubles to usd. Variables Store values and reference them by name. Write tax = 0.2, then price + price * tax — Calculo handles the rest. Use natural, multi-word names like monthly rent. Templates Build reusable calculation sheets with editable inputs and live outputs. Tap Play, fill in the numbers, get the answer. Perfect for recurring tasks: VAT, mortgage, tip splits, unit costs. Graphs Visualize arrays as line graphs directly on the canvas. Define a range, write an expression, see the curve. Organized notes Create multiple notes, organize them into folders, and search across everything. Your calculation history lives where you left it.
