So I recently got invited to a Dropbox folder with the an ipa for the iPhone app. I have to say, I love it. I love it a loooooot.
Although this might not have been what you guys were going for when you made this site, one of the major reasons I've used it over something parallel like Anki or Surusu is that it's soooo pretty. My handwriting's awful, so seeing me draw out these gorgeous kanji's a pretty big bonus for me. And the app's definitely beautiful. It's a pleasure to work with. I sit at my desk, with my wacom tablet, and then proceed to Skritter on my iPhone.
So, yeah, that's all I had to say. Fantastic job, guys. Just wanted to let you know how impressed I was by it.
