User Reviews

Users commonly praise Calculator-- for its large numbers, bright colors, ease of use, and value (free with a one-time purchase). Recurrent concerns focus on a loud keypad sound with problematic mute options, and orientation issues (limited or inconsistent landscape support). Some reviewers also want more advanced features (parens, trigonometry) and clearer operation indicators. Overall, accessibility and simplicity are strengths, while sound controls and rotation support are the main downsides.

Pros

Large, easy-to-read numbers improve readability for visually impaired users.
Bright, colorful UI that helps visibility and engagement.
Simple, intuitive interface and reliable performance.
Free to use with a reasonable one-time purchase option.
Backup/undo feature helps correct mistakes without restarting.

Cons

Loud keypad sound; hard to mute and can be disruptive, with issues persisting after updates.
Orientation/rotation problems; not consistently usable in landscape and some displays show sideways.
Missing some advanced functions and UI cues (e.g., parentheses and sin/degree buttons; last-operation indicator).
