Ratings and Reviews

Beautiful... but I'd change one thing.


It's beautiful, it's functional and it's comprehensive. But maybe too much so?

Perhaps it would be an idea to have the option of a scaled-back interface, offering only the most common types and units of conversion. Naturally the others could be added back as and when needed - but the app feels a little cluttered and in need of customisation before delivering that perfect user journey.

All in all, though, love it. Well done!

Great App, Beautiful Upgrade


This is my favourite unit converter app an I've tried a few. It doesn't take up too much space, and works fluidly and logically.
One or two minor glitches with the upgrade need to be ironed out before I give this the full 5 stars:
Some units display the formula rather than the result if the base unit is very small. (E.G. 1 second converts to 3.17*E-10 centuries)
As a runner I'd love to see minute/miles and minute/kilometres added into the Speed Category.

Simple, powerful and easy to use


This is the best in it's category with an incredible range of conversions available to a user. One of my most used apps and never lets me down.
