Adding Machine 10Key iPhone

Adding Machine10Key for iPhone provides reversed-entry arithmetic with an editable saved tape.

Our take

Pick it if an adding-machine workflow suits one-handed phone entry

Selectable total-key placement and an expandable keypad balance input space with visible history.

Keep in mind: Do not attribute the universal iPad edition’s TypeTone or full-size keypad to this phone edition; ten-key entry differs from a normal calculator.

What you can do

  • Reversed operator entry and total key
  • Editable tape lines comments and saved files
  • PDF sharing and selectable display formats

Good for

  • People familiar with traditional adding machines

Consider alternatives for

  • Users needing spreadsheet logic or iPad-only audio-guided entry

Limitations & considerations

  • Captured minimum: iOS 12.4.
  • Do not attribute the universal iPad edition’s TypeTone or full-size keypad to this phone edition; ten-key entry differs from a normal calculator.

Privacy & permissions

Tape files can contain private financial calculations; email or cloud exports deliberately send selected records outside the app.
