From the developer:
iKanji is a Japanese kanji and vocabulary study app for the Mac.
The app lets you search by selecting radicals, the elements that make up each kanji. This is great for quickly identifying kanji where you don’t know the meaning or readings. You can also perform searches based on almost every attribute of a kanji.
iKanji features a vocabulary browser that lets you search for words and build up sets to practice.
