The New And Improved List Of API and Third Party Apps

I am not entirely sure about jakeipuu, but I vaguely recall reading somewhere else that it has been unmaintained for a while.

I think you can select what to study in the durtles app, it is just burried in the lesson settings somewhere, but only on a global basis. For instance, you could say I want each lesson to be as many radicals as possible, 1 kanji and 4 pieces of vocab. The most supported android app is currently smouldering durtles.
