No Help

Does not have any help for people that want to learn and do not have much experience with high end calculators. Should be help guide with basics of math , fractions, polynomial and examples how to use in calculator. The conversions pretty easy to understand. Wanted to help kids with graphing and pre algebra but no help on what different functions are for.

Great Start to a useful application

Great Start to a useful application. Only thing that needs improvement is making the UI conform to Windows 8 Metro style. No need to clutter the screen with settings icons, etc since we can swipe from the left for the charms bar or right click for bottom/top menus. Great deal for the money though.

Great but needs more "Metro"

This is an incredibly full featured calculator. The conversion features, graphing, and regression features are very neat. Would be nice to see the binary values in the base conversions calculator at all times (just like in the default windows calc). Also needs to conform better to Metro design standards i.e. remove the icons on the side and place them at the bottom and be visible when you swipe on bottom edge. Also place email option in share charm. Glad to see you have snapping working well

Good Calc and conversion tool.

Would be good if load time was a little faster, but otherwise really nice.

Missing features, full of bugs

I bought the full version by unlocking all of the modules, big mistake. the calculator is disabled since the last version was released. cannot save, import or export data or graphs. underdeveloped interface, non-responsive customer service. Big waste of money and time. Don't bother.
