Notebook calculator (ge-calc)

A calculator that keeps results and notes together, with Siri and Shortcuts capture, memo-to-formula conversion, and easy CSV or Markdown sharing.

ge-calc is a calculator with history that keeps your calculations as notes. You can save not only the numbers but also what they were for, so it is easy to review, verify, and reuse them later.

It works well for estimates, invoices, expense checks, household budgeting, and quick dimension or tax calculations. Instead of rewriting numbers by hand or copying them into another app, you can calculate and keep the record in one place, then share it when needed.

Key features • Keep calculation history as notes • Continue writing in the memo area while you calculate • Organize notes by page • Share results and notes easily • View the calculator and memo together on iPad • Support tax calculation

Used by many people over time, ge-calc is built for calculations that stay useful after you press =.
