iPhone/iPad apps for keeping track of collection

Anyone have any good recommendations for iPhone/iPad apps for keeping track of your comics? I used to use an app on my android phone but it looks like it doesn't exist for apple.

Any help would be appreciated. Thanks

You mean an app to store your comics on your mobile device and read them on it? Or just to keep track of the ones you have?

Just to keep track of the ones I have.

I dont understand. WHat do you mean keep track of your comics. Do you mean like the comixolgy app?

If you have iOS 7 then Pages and Numbers are free apps by Apple. They're good for making lists I guess. For viewing comics I like to use Comic Zeal.

On android I used the Comic Books Collector

But I am having a hard time finding something similar on the apple app store.

Comixology
