The best of it's kind!

Love this app. This is a very helpful app when u need to convert units (for work in this case) I have another one and I was happy with it, till I got this one. It's simple to use and love everything about it. There's always room for improvement, but I haven't found anything yet... Good work guys! LOVE IT ;-)

Great converter!! And FREE!

Simple and easy to use layout! The ads are kindof annoying but I prefer this app above others for it offers more conversions than its competitors. It's worth the download, for its free , and you never know when you'll need to use it!

Works as intended.

I was using another free conversion app not too long ago, but that previous company decide to barrage it with ads. So far this one has been the perfect replacement and seems to do all the converting I need.
