Make The Total Readable

Paper Tape Calc keeps the running total and the reasoning together. It is intentionally smaller than a spreadsheet: keypad, tape lines, notes, presets, and a clean share output.

Paper Tape Lines

Each completed calculation is saved as a visible row, so you can review the path to the total instead of only the final number.

Notes On Lines

Add short labels like lunch, tax, materials, or hotel directly beside the math that produced the number.

Clean Copy

Share the tape as plain text for invoices, trip budgets, quick checks, and personal records.

Built For A Small Paid App

No login, no bank connection, no camera scan, no server sync, and no analytics in 1.0. The app stays narrow: calculate, annotate, review, copy.
