About this app
Adding Machine keeps everyday arithmetic visible.
Instead of hiding the sequence behind one result, it shows a paper tape with every number, operator, running total, and final Total. That makes it easier to check a receipt, work through household spending, prepare a small invoice, or correct a calculation without starting again.
WHAT YOU CAN DO
• Build a tape with +, −, ×, ÷, percent, subtotal, and total.
• Tap any line to edit its operator, value, percentage, or label.
• Insert a line above or below an existing entry.
• Delete a line or cancel an edit safely.
• Save and share completed tapes with Pro.
• Choose decimal-place and visual settings that fit your work.
PRIVATE AND OFFLINE
Adding Machine does not require an account, location, contacts, camera, or notification permission. Calculations are designed to work offline and remain on your device. There are no ads and no telemetry service.
ONE-TIME PRO UNLOCK
Pro is a one-time purchase, not a subscription. It unlocks saved tapes, sharing, themes, and additional decimal-place controls. Restore is available on the same store account when you reinstall.
Adding Machine is a focused paper-tape utility: visible work, quick correction, and a clear answer.
