It does what it says, so no complaints there.
I just cant get over the fact that it doesnt allow much customization to the aesthetics of the app itself. As a mac user I want it to be personalized to my preferences. E.g. should have the option to hide the side bar, I dislike having to drag it every time I start up the app. There should also be the option of a shortcut search or even having the option of having the app in the menu bar if you so choose.
I also dislike how the sepia feature (which is a must for reading apps) colours the text. I like the text remaining black on the yellow background. Easy on the eyes. Just dim the black a bit. Dont make it brown! (personal preference of course).
OH, and the popup window when you are typing something into the search box is ugly and deters from the entire app.
Anyways, the app is great for what it is. But, I would like to see it do a lot more for the price. What makes this app any different then just opening up a browser and searching on wiki and then viewing the screen through a reading mode such as Clearly by Evernote? Nothing! If you want your app to stand out, make it do MORE!
I would not advise getting this app, unless you dont like using a web browser, then by all means go ahead.
