User Reviews

User reviews are mixed: many praise ease of use, decimals, and the vintage UI, but recurring decimal bugs and faulty percentage calculations render it unreliable. Ads and rating prompts irritate users, and the keypad layout plus missing backspace add to usability frustrations. Overall, the app has potential but core math accuracy and UX issues limit broad satisfaction.

Pros

Easy to use and intuitive.
Supports decimal numbers.
Visually appealing vintage look and logo.
Can reuse recurring numbers without re-entering.
Overall positive performance for some users.

Cons

Decimal handling bugs: decimals are not recognized or are misinterpreted.
Incorrect/inconsistent percentage calculations (e.g., 100 × 50%).
Intrusive pop-up ads and prompts.
Nonstandard keypad layout and missing backspace (unusual button positions).
Persistent rating prompts that cannot be disabled.
