Had some trouble with initiating the ad free version, but the developer promptly fixed the problem. I like the app and will probably get the complete version soon.

I just installed, it seems to have a great way of giving all possible conversions (lengths /widths) unfortunately it takes to long to open upon initiation and then its flooded with advertising, too bad! I like the layout/accuracy but quick use is also essential. unfortunately I believe I will be uninstalling... it should be faster than googling the conversion! good luck!
