Has Great Potential

The Good: Easy on the eye font and resizable window. The Bad: You have to click the = sign you can't just hit enter like you can in the windows calculator. Also strangely the bottom of the numbers are below the bottom outline of the box the number sits in. Another thing I don't like is you can't just change it to a basic calculator view 0 through 9 + - / * = CE C The rest of the keys are a distraction when doing basic math functions.

Calculator X8

Love the large numbers and the background color. Showing the answer in bold is also a plus, it makes the answer stand out.

Please change it to UWP because Win8 programs feel really clunky on a Windows 10 laptop

Best calculator yet - Rotten Calculators

Clicking is fast, love that. Easy to access, easy to download. Good format, but should change the division symbol into the normally used symbol. Great job!
