A while back I posted about the glaring deficiencies between the paid-for Aedict3 and the freely available Aedict 2.
This week, Aedict 3 was updated and with it, so far as I can see, all of the features from aedict 2.
Its reassuring that the author is still working on the project, and I feel that my meagre investment in buying the paid-for version is starting to go the distance. That said, I'd still say that aedict3 has done little more than catch up with its predecessor. There are some nice changes, but these are entirely cosmetic so far as I can see. Nonetheless, it feels like there is momentum in the project, and perhaps aedict3 will soon surpass version 2.
The bottom line at the moment is that I still recommend version 2 if you're starting to seriously read in Japanese.
EDIT: Aedict 3 has finally overtaken it's older sibling, and I think people should now start seriously considering getting hold of it, especially if they read a lot of Japanese on their device see this blog post
