Calculator Expert
Calculator Expert is a high-precision calculator app for macOS that emphasizes mathematical accuracy beyond standard floating-point arithmetic. It supports basic arithmetic operations, trigonometry, roots, logarithms, and over 25 mathematical functions. The app stores calculation history, allows editing of previous calculations, supports multiple angle measurement systems (degrees and radians), and preserves state between sessions. It is designed for both everyday use and technical mathematical work, with an interface modeled after the iPhone Calculator app.
AI Recommendation
1 suggestionCalculator Expert appears to be no longer actively maintained — the most recent search results date to 2012 and 2025, with no clear evidence of updates or a native Apple Silicon build in recent years. The vendor's social media links (Twitter, Facebook) are references only to legacy accounts from 2012, and there is no indication the developer has shipped a native build or published release notes since then. Because the app is Intel-only, it will stop launching entirely when Apple removes Rosetta 2 in macOS 28 (September 2028) — less than two years away. If you rely on Calculator Expert for important work, you should begin migrating to a maintained alternative now. macOS Sequoia and later include a built-in Calculator app with reasonable precision, and for advanced mathematical work consider open-source options like Qalculate! or commercial tools like Grapher or Wolfram Mathematica, all of which run natively on Apple Silicon and are actively maintained.
