Akebi for Android is pretty good. For a while I used the Nintendo DS Japanese dictionary (Rakubiki Jiten) for the ability to do stylus-based character recognition, which was less frustrating to use than the Windows IME pad feature. Akebi works reasonably well for that function.
I only just started learning Chinese, so I haven't looked at Pleco yet and can't really compare them.
I'll agree with some other comments that once you get into the area bordering intermediate and advanced proficiency there are many fewer resources, but by then you have a better idea of what you don't know, and and can use your existing base to sort of plot a path to fill those gaps.
