Numi
Numi is a desktop calculator for macOS that lets you write calculations in natural language and mix math, units, currencies, and dates in one note.
What is Numi?
Numi is a calculator app for macOS focused on quick calculations written as plain text. It helps people solve everyday numeric tasks without building formulas by hand, so you can type expressions such as percentages, currency conversions, unit conversions, date offsets, and time-related calculations in a single note-like workspace. The app is useful for budgeting, estimates, shopping comparisons, travel planning, and general desk work where math and written context belong together. Numi also supports multi-line calculation notes, which makes it convenient for keeping running totals or working through a small set of related figures. It is published by Dmitry Nikolaev and is aimed at users who want a faster, more readable alternative to a traditional button-based calculator.
Key features
- Write calculations in natural language instead of using only calculator buttons

- Keep multi-line calculation notes with results updated as you edit

Safety overview
Status: Safe
Numi is a legitimate calculator app, and its normal behavior is consistent with that purpose. If you use features such as sync or online conversions, some entered data may be processed through connected services, so avoid storing sensitive financial or personal details in calculation notes unless you are comfortable with that use. Removing the app can also remove its local notes, settings, or extensions if you delete related support files.
Recommendation: Keep Numi if you use it for everyday calculations, conversions, or note-based math. If you no longer use it, you can remove the app; just export or copy any saved calculation notes or custom extensions first if you want to keep them.
