Alamak!

While many Singaporeans bashed this app as insulting to them (well no comment on that) I myself liked this app for its information. How consistent they are? Just google lah! After more than 10yrs in SG I'm still a dummy on their common lingo, so this helps a lot! Teh-c any one?

Let's do the twist

Learn the basics of balloon twisting through this app. You can rotate and zoom the illustration to get a better look, best of all this app is free! Yey!

Romaji

Want to send mesages, emails or create notes with these cool characters?

(*^_^*) ＼(^o^)／ (^-^)/（＾◇＾）

Just add a new Keyboard to your General Settings and choose Japanese Romaji. To use, in your text editor tap the globe key and select the Japanese keyboard then tap on 123 key and you will see the smiley key, tap on it and dazzle yourself with lots of Romaji characters!
Enjoy!!!

Not a WOW app but the info is useful enough for me :)
