A-CalcM is a calculator that keeps your values and operators in "calculation lists", so you can check every number as you go and fix just one part later. ■ Features • Calculation lists: calculations are recorded in lists (columns) with a running total. Switch between lists with tabs • 4 presets: Simple 0 / Simple 9 / Preset M (classic A-CalcM) / Preset G (everything included) • Compare lists: show two lists side by side (iPhone, portrait) • Subtotal of checked rows, and copy or move checked rows to another list • Text notes: add item names or purposes to cells • Memory (M+ / M− / MR / MC) kept per list • +Tax / −Tax for tax-included and tax-excluded amounts (set the rate in Settings) • Choose rounding and decimal places • Share & export as an image or text. Text is tab-separated, so it pastes straight into spreadsheet apps • Back up by saving to and importing from a file • Customize button layout and size, and font sizes ■ Reading receipts (Preset G) If you already use an AI app, pass it a photo of a receipt, paste its answer, and the rows go into a list. Before importing, you can check that the rows add up to the printed total. • The photo goes directly to the AI app you pick in the share sheet. A-Soft does not receive it • Accuracy depends on the AI model you use. AI is not perfect, so always compare the rows with the receipt before importing ■ Pro (one-time in-app purchase) Available in Settings. • Hides the ad banner area • Up to 31 lists (3 without Pro) • List lock, which protects a list from AC and MC (Preset G) • Send up to 20 receipt photos to the AI app at once (1 at a time without Pro) If you bought "Remove ads" before, it works as Pro.
