Liking it so far. Only one small complaint. In the unit converter, it would be nice if I could scroll through the categories instead of all of the units. Yes, I noticed there is an alphabetical shortcut bar. For me, category scrolling makes more sense and is faster. Other than that, I'm pleased. Purchased for the financial calculator since I didn't have one installed already.

@diggity, that's good feedback, thank you. Windows provides a much better UX for grouped lists with the semantic zoom control (in my opinion), and for the time being I've just tried to match this as closely as possible with the native list controls on iOS and Android. I think the alphabetical shortcut bar works well for the currency lists, which isn't divided into categories like the constants and units and is just there to aid navigation. I'll experiment with some alternatives, although I'll probably wait until I add support for iPad as that might change things again.

When I first released the app on Windows Phone 7, I had a search facility but it didn't make it into the Windows Phone 8+ releases. I plan to bring this back asap to make finding constants, units, etc. much easier.

Thanks for the purchase and your support. I'm glad you like the app!

No problem. By the way, I'm using iOS 10 beta and cannot rate on App Store. I will rate once iOS 10 is official.
