User Reviews

Overall, reviewers praise One Scientific Calculator for its clean, minimal UI, fast performance, and powerful feature set, including unit conversions and a helpful history that’s easy to copy from the home screen. It’s often described as the best calculator app and a must-have. Common drawbacks include crashes after updates, missing advanced functions (binary calculations, arcus trig, e), grapher issues, and several UI annoyances (no auto dark mode, intrusive clear-message, small landscape buttons). Improvements to stability, advanced math features, and graphing would boost it further.

Pros

Clean, minimal UI with fast performance and a strong feature set (including unit conversions).
History display on the home screen and easy copying of results.
Regarded as one of the best calculator apps, a reliable and must-have tool.
Powerful scientific capabilities that handle a wide range of calculations.

Cons

Crashes or cannot be opened after updates (stability issues).
Missing advanced functions (binary calculations, arcus trig, e) and some features expected by power users.
Grapher has issues (ln(x) graphs cause errors) and overall graphing robustness could improve.
UI annoyances: no auto dark mode, intrusive messages when clearing, and small buttons in landscape.
History/formatting limits (last 50 entries, no comma separators, precision concerns).
