Write "29 dollars an hour, 22 hours a week, for 4 weeks." Tap AI. Get 2,552. InkCalc is a calculator you write in sentences. No re-punching numbers into a keypad, no wondering what that figure was for. Units, live currency, dates and percentages all work inline, right in your notes. Write expressions line by line and results appear on the right, accumulating over time alongside written notes — a calculator built to be kept open as a long-running notebook, not a scratchpad. For iPhone, iPad and Mac. Universal Purchase means one subscription covers all three. Starts with a 1-month free trial (auto-renews after that — see SUBSCRIPTION below for details). — AI-NATIVE ACTIONS (subscription required) — AI — Natural language to expression Write "29 dollars an hour, 22 hours a week, for 4 weeks", tap the AI button in the toolbar, and AI converts it to `29 * 22 * 4`. Fix — AI fixes errors With one tap, AI replaces a parser-failed line with a corrected expression. Summary — One-to-three-line note summary AI reads your whole note and summarizes the intent and conclusion in plain natural language. Intent — Intent inference from comments Write a question comment like `# Monthly communications total?`, and AI analyzes the relevant lines and inserts a summing formula directly below the question.
