Radiant needs to do more work on their Unitica conversion app. First of all, the demo video which is intended to demonstrate how to use this app, and which was once accessible from the support tab, has not been working for over a year. The problem I have had with this app from the beginning is that it simply does not work! Upon opening the app to show all of the various catagories for conversion I may choose the conversion of temperature category: on the left-hand side of the screen I choose the fahrenheit scale for conversion to the celsius scale on the right-hand side of the screen. When I align the two scales directly opposite one another, with the direction-of-conversion arrow pointing to the final conversion modality, there is then no further ability to imput any information such as specific numeric value(s) to be converted. A dead end is reached! Although the demo video is no longer accessible from the app's support tab it is still available from Radiant's web site. The problem with the demo video is that, in my oponion, is it does not demonstrate clearly enough how to begin and complete a conversion--it rushes too quickly through the process without an actual step-by-step demonstration, i.e., I should be able to perform any conversions by watching and copying each step shown in the video but I cannot because steps are omitted as the demo video is too rushed. I think this app has good potential but right now it's author needs to devote more time to improving the app by simplifying the steps used to make conversions, and especially, by adopting a much more intuitive approach to the User Interface.

I don't understand why conversion apps keep rounding bytes to 1000 per K instead of 1024. It's 1024. Every single conversion in the data section above byte-size is wrong. I don't care if OS X does it because it looks easier for non-technical people. If I'm converting numbers for my job, and I'm a Software Engineer, I need accurate numbers not round ones.

This app has every conversion tool you could ever need. I've downloaded a few conversion apps out there and this one contains the most units by far. I work in a research lab and it's nice to have lots of conversions on hand. The interface is easy to navigate and the units you use the most can even be bookmarked for faster access. The app does as advertised. A+

This app not only allows the user to convert almost anything, but is also beautifully designed and extremely customisable. In my opinion, it's worth paying for this app rather than using a free, inconveniently designed unit converter.
