I don't have any experience with Apple YET, but I will soon!

Here's my stash of Apple staves and billets cut from a non-producing tree from my parents' yard:

The other posters are spot on, Apple is gnarly, twisted, and has many knots. Every one of these will be "character bows".
I think Tim Baker listed Apple's SG at around .67 in the TBBIV. That puts it in Pecan density or light Hickory, so I'm very hopeful I can get at least one good bow out of this stash.
I'd say go for it and post your bow(s) up! Would love to see more Apple.
