Customer Reviews

Very handy and highly versatile.

I don't like to give 5-star reviews without due justification. So, I tried to think of anything worth knocking a star off and simply could not. It's great at doing just as advertised. I frequently use it, find the unit suggestions really handy, the interface is intuitive and has some customizable features, and it has never had any glitches on any iOS update or any iPhone. I bought this version after getting tired of ads popping up half way through entering something to convert on the free version (that timing is a little underhanded, I think, but I understand that everybody has to make $ somehow). Definitely glad I paid for the "full" version! I haven't noticed a functional difference aside from absence of ads (which is VERY nice), but I've never come close to using more than a fraction of the vast plethora of units available on free or paid versions. Definitely recommended!
iPhone 6; iOS 9.3.1.


I have used quite a few converters and this is the one that I nearly always use. It has a very plain, almost boring interface (a benefit, as it is 100% function) but easy to use. It converts multiple different units quickly. There is no messing around with setting what units you want or don't; just enter an amount and start typing your units and they pop up. I got this for free, but would gladly pay $1-2 (I'm not sure of the price).

Excellent conversation app

Excellent conversion app. I am a Physicist and this app has most units we use and more importantly actually has the conversions correct.
The ability to adjust the font size is GREAT and makes this app very usable and easy to read. I have used most other conversion apps but have found this one to be by far the best.

Please continue to expand on more units, especially the rare or outdated ones as they come up from time to time in my work.
