iOS vector drawing app?

[SET318MLP 55]

Hey I'm looking to getting into vector drawing and I'm wondering if there are any good vector drawing apps out there for iPhone (I don't have an iPad). I'm trying to find something to kill time on the bus ride to and from school.

I use Abode Ideas really easy to use. It's free and really really simple.

You Doodle is simple.

But eh.

It's not for vectoring.

Idk.

It CAN be used for vectoring.
