Uno Calculator

Uno Platform

About this app

The powerful Windows Calculator receives a makeover from Uno Platform with a wide variety of features. From calculations to measurements of size, temperature, speed, energy, currency and more, the calculator is a powerful one-stop-shop for all calculation-related needs.

Ratings and reviews

Nearly perfect but very slow, especially when changing between modes (why is the side menu so slow to pop out?) and even units in the conversion module. Also, I don't like when the buttons leave empty space on the sides and just in general how often my fingers need to stretch to reach a button.

Free, works reasonably well. However there are costs to making an app cross-platform. Comparing with RealCalc, for example - Uno Calculator is about 75 times larger to download (135mb vs 1.8mb). The UI is a bit laggy on a reasonable phone (Nokia 7.2) - you'll wait a couple of seconds to open the app menu or change the app layout. App uses about 120mb RAM too - where RealCalc uses about 5. It's great for the price, but it's a demonstration that the Uno Platform perhaps needs some perf tuning.

One of the things I miss switching from Win10M to 'droid was the Windows Calculator. By far the best most useful calculator app available on any platform. While this port is missing some of the features (and the fun conversion comparisons... how many elephants?), and the performance is a little laggy, it is good to have a regular calculator, scientific calculator, programmers calculator and unit converter all in one app, and it works in spit-screen, so yay!
