Customer Reviews


Becoming my favorite conversion app because it lets you convert with a minimum of fuss & get back to whatever you needed the conversion for! An especially helpful feature is the ability to star your most used conversions, by category and/or by specific measurement. And the new theme is both attractive and non-distracting.

Excellent conversion app

I love this app! It's gorgeous and super intuitive to use. It has devoted developers that continue to update it with great new features (like Bitcoin support). This is the only conversion app you'll ever need - get this now!


I don't use this app every day, but when I need it, it's right there. Lovely display with more than enough conversion options. Buy it.
