For photo editing software this is pretty cheap! The interface is quite nice and simple just like you expect form Apple. Labelling is clear and every button is distinctive and well labelled. All the view and recognition buttons are in the top right of the interface and well labelled and the view options are brilliant, giving you easy access to a variety of ways to view images. The loupe feature is brilliantly done and allows you to clearly zoom into the image to see exactly how sharp it is. The problems I have with the software are to do with the adjustments though unfortunately. All of the adjustments are very delicate and conservative so a lot of the time you are left wondering if the adjustment you made actually did anything. This is especially true of their noise reduction feature which is as much use as a chocolate fireguard in a forest fire. The software does however shine when it comes to printing! It makes the printing of photos very simple and offers simple options to help you do justice to images when you print them. The exporting is slightly weak however as it doesn't offer any real options past file naming and basic file format with no major adjustments like quality of file etc. Overall, if you pay the app store price this software is entirely worth it if you want to spend a small amount of money to give yourself a decent workflow for RAW files but if you have more to spend, do yourself a favour and get Lightroom which trashes this software.
