User Reviews

The app is visually appealing and generally useful, with strong praise for its design and usability. However, it suffers from precision errors in basic math, lacks key features (history, undo, preferences), has inconsistent keyboard support, and displays UI issues due to ads. These recurring concerns outweigh the positives for someone needing reliable, precise calculations.

Pros

Elegant, simple, and visually appealing design that resembles the iPhone calculator.
Generally useful and easy to use for everyday calculations; several reviewers call it helpful or indispensable.
Positive endorsements that the app is attractive and suitable for students and non-expert users.

Cons

Floating-point precision issues lead to incorrect results in simple calculations (e.g., 617.14 - 602.45 = 14.689999999 and 177 - 170.21 = 6.789999999).
Missing essential features like history/tape, undo/back, and user preferences (even the free version).
Inconsistent keyboard support: Enter key not reliably functioning as equals on Mac keyboards and external number pads; exponent/power operator not available.
Display/readability issues due to bottom banner ads and the inability to resize the display.

Recent reviews

Unfortunately, this calculator can’t do math… and as that’s the only thing I need it to do… needless to say, it didn’t work out. 617.14 minus 602.45 does not equal 14.689999999 Close, but not close enough.
