What are the best Japanese dictionary apps on IOS and Android that support drawing the kanji (when you don't know how to spell it)?

I'll be needing it for Japanese Language school to look up words in the middle of class or in everyday life so I probably won't know the stroke order.

I would prefer Android because of flash support (and I hate iTunes). I like Anki on IOS, but I need to use Chinese keyboard for Kanji drawing, which doesn't always work. My favourite dictionary is http://jisho.org/ and an Android version with Kanji drawing would be my dream app.

There are a bunch of them for Android mentioned here.

EDIT: I guess most of those are just keyboards. 7notes with mazec, and WWWJDIC seem to do handwriting though.

Also, for iOS, Midori, Daijisen, and Daijirin listed here can do handwriting.

Aedict for Android

It has built-in handwriting recognition as well as search by radical and SKIP.
