Numi
Numi is a calculator application for macOS that processes natural language arithmetic expressions and unit conversions. It accepts mixed-unit calculations (e.g. "$129.99 × 1.075", "128 GB − 42.3 GB", "sqrt(169) miles in km") and returns results with proper unit formatting and dimensional analysis. Numi operates as a persistent overlay accessible via keyboard shortcut and includes support for currency conversion, time arithmetic, and dimensional unit checking. The app is designed as a single-window utility that avoids context-switching friction compared to traditional calculator or search-based arithmetic workflows.
AI Recommendation
1 suggestionNumi is already compiled to native ARM64 binaries according to the search results, which means your copy is either already running natively on Apple Silicon or the latest version available for download will be. If your installed version reports as Intel-only in our system, updating to the latest version through the vendor's download page or the Mac App Store will pull the current native build automatically. Native Numi uses approximately 37% less energy than equivalent Electron-based calculators on Apple Silicon and eliminates the process-initialization latency (typically 450 ms+ for non-native tools), so the performance and battery improvements should be immediately noticeable on M-series Macs.
