Great all around calculator for technical purposes.

It's a great substitute for a scientific calculator. For my uses, all functions are there. It's not easy to use for conventional purposes though. PS: This app is a little unstable in it's updates.

Very very well done app. Runs smooth and has tons of options. The country flag for each currency is a great touch! Quit griping about paying for extra features (regardless if they used to be free) as that supports developer. This ones definitely worth supporting!

The best calculator app on windows IMO

I've been using this app on my windows phone for a very long time. With the windows 10 version, it is really great on the desktop too! It's fast and smooth.

I used to love this app, but ever since the 'big' new update, the live tiles dont update any more. I used the currency tile all the time! Please bring it back! :(

Nice design. Clean interface. Very useful. The goto app for calculating on Windows Phone.

I like liked this app a lot... But... It used to be Free, even if it was with ads... Now, since the last update, the currency converter and other features ask for purchasing the pro version. Sucks!!!

Not easy to use

If your looking for easy answers quickly this isn't the app for you.

Needs windowed mode

Great app. However in Windows 10, it runs as a full screen app. Need to update to allow it to run in a window.

App details

Version notes

Version 5.0 • Upgrades the app to native Windows 10 UWP. • Allows the app to be run in a window on the desktop. Version 4.2 • Fixes the x⁻¹ (reciprocal) button causing the app to crash because of an incorrect button mapping. • Fixes the app crashing when the OS is unable to update the live tiles. Version 4.1 • Fixes the app being unable to launch on Windows 10. Note, a native Windows 10 version is in development, which will allow the app to be used in a window on the desktop. • Auto-hides the navigation bar for devices without hardware buttons to prevent the navigation bar overlapping the lowest row of buttons. Note, the auto-hide option must be enabled in the phone's settings to enable this feature. • No longer scaling the font according to the OS setting to prevent layout issues. Version 4.0 • Added Financial calculator. • Added implicit multiplication, e.g. type [2] [sin] [30] instead of [2] [×] [sin] [30]. • Rebuilt as a Universal XAML app, allowing settings, history, memory and favourites to be shared across all devices.
