Unitto — calculator and unit converter

Unitto is an open-source Android application that combines a calculator with several conversion tools. It is listed in the Productivity category and is intended for calculations, unit conversions, date work, time-zone conversion, and body mass index checks. Its tools bring these related tasks together in one application.

The calculator supports trigonometric functions, fractional output, and an optional Indian numbering system. A home screen widget provides access to the calculator from the Android home screen. Users can copy, paste, save, and share expression results, supporting both the entry of calculations and the reuse or distribution of their outputs. These functions make the calculator suitable for handling results that need to be retained or passed to another context.

The unit converter contains 601 units, supports favorite units, and allows unit groups to be organized. Its smart search algorithm helps users locate units within those groups, while the currency converter uses the internet. A separate home screen widget is available for the converter. Unitto also includes a date calculator for adding and subtracting dates, calculating differences, and creating calendar events, along with a time converter that supports favorite time zones and time-zone labels. The body mass index tool provides instant and accurate results.

As an Android download, Unitto fits MirrorNest’s Time & Calculators catalog category. MirrorNest stores the official build directly on its own storage and scans it for malware before publishing it. The open-source license indicates that Unitto’s source is available under an open-source project model.
