thumbs.work

Think with your brain. Work with your thumbs. thumbs.work is a notepad that does the math for you. Type a line in plain language and the answer appears right next to it. No equals button, no modes, no switching apps. CALCULATE AS YOU TYPE Every line evaluates instantly. Add up a bill, split it four ways, work out a budget. Change units for recipes in a single number. A full scientific set is built in: square roots, powers, logs, trig, factorials, and constants like pi and e. CONVERT ANYTHING Length, volume, weight, temperature, speed, area, data, even CSS units. Just write "10 km to miles" or "2 cups to ml" and get a clean answer. SKIP THE TIME ZONE MATH "9am PST to UTC", "time in Tokyo" — written the way you'd actually say it. RUNNING TOTALS Numbers on consecutive lines form a block. Type "sum" or "average" to total them, and "prev" to reference your last result. SEPARATE SCRATCHPADS Keep one for everything... groceries, travel, bills, a project. Rename, reorder, and search them. Import and export as JSON, Markdown, CSV, or plain text. A notepad for your thoughts. A calculator for real life. Works with plain text, markdown, and our own .calc files. MANY THUMBS, NO LIMIT Keep as many documents of every type as you like, free.
