Unitto — calculator and unit converter

Enter an expression in Unitto to calculate it, convert units, work with dates and time zones, or check body mass index from one Android app. Unitto is an open-source Productivity application whose calculator handles trigonometric functions, fractional answers, and an optional Indian numbering system.

A calculator widget places quick access on the Android home screen, while results can be copied, pasted, saved, or shared for later use or transfer to another context. The converter covers 601 units, lets you mark favorites, arrange unit groups, and find entries through smart search; its currency conversion uses the internet.

A second widget opens the converter directly from the home screen. The date calculator adds and subtracts dates, finds the difference between dates, and creates calendar events, while the time converter supports favorite time zones and labels for those zones. A body mass index tool returns instant, accurate results.

The current version is Titanium yellow and supports Android 6.0 or later on arm64-v8a, armeabi-v7a, x86_64, and x86 architectures. Its open-source Android distribution suits students, travelers, developers, and anyone who needs calculations, conversions, scheduling dates, or comparing times in one place.
