NANODRAGON  Perfect for my Thai vocabulary needs, and free too!

The best thing about it though is that it just keeps getting better and it seems every time I start up the app there's an update with new and useful features.

Thanks Mr. Developer!

NANODRAGON  Excellent application. It works as advertised and since it runs in the background (unlike carrafix, which doesn't work anymore anyway) it's great to have around. Not to mention that it's the only program of its kind available for osx.  
(Version 1.1.2)

ANONYMOUS  Great software. The developer is a great guy who listens to user requests and answers very promptly. The app itself works well and (IMO) has the nicest graphics of all the battery widgets out there. And about the 5€: you can find those in the subway if you're lucky. I gladly paid them for the excellent and friendly support I received.
