User Reviews

Overall, users praise Adding Machine 10Key Universal for delivering a faithful 10-key experience with a convenient paper tape, excellent audit trail, and easy setup across iPhone and iPad. The tape/history feature and the ability to save multiple lists make it a strong replacement for traditional calculators for bookkeeping and spreadsheet tasks. Most reviewers find it intuitive and reliable, with frequent compliments on the two-decimal formatting. A few issues crop up, notably a decimal display bug in Fixed+ mode on some devices and intermittent nag prompts; a small minority report save/export problems on newer iPads.

Pros

Realistic 10-key adding-machine feel that mimics a physical 10-key device, making it easy to learn.
Built-in paper tape/history for auditing: you can review entries, print or email the tape.
Easy to learn and intuitive, especially for users familiar with 10-key calculators.
Ability to save multiple tapes/lists for different tasks.
Automatic two-decimal formatting and cross-device consistency across iPhone and iPad.

Cons

Decimal display bug in fixed+ mode where totals show non-zero decimals or are displayed incorrectly.

This App works very well, perfect for balancing your check book and adding long spread sheets.

This acts just like the old physical 10-key machines. There was a slight learning curve because I haven’t used a 10-key for 20 years or more. But the app works really well. It’s certainly worth the price.
