What’s the best app for tumblr?

Sorry I’ve been so quiet here and on my blog/other sites lately. The biggest reason for this is Mid-Ohio Con which is this weekend. (October 22nd-23rd) There’s been some arting and then there’s been lots of wrangling files, chasing after paperwork so I can do more cons in 2012, and other hassle. Anyway, come to the show, it’s gonna be a blast. I’ll be taking plenty of pictures to post on here.

The title of this post is a question I’d like you kind folks to help me answer. I recently got an iphone and I’m trying to improve the way I browse tumblr on it. I follow a lot of art, pinup, etc. blogs and it’s nice to scroll through them with a flick. My problem is I’m that obsessive compulsive type that must click back to see every image. (Infinite scroll is my nemesis) If it’s an artist or model I want to check out later I Google Image Search their name and bookmark it. I need to try going to a nice app that lets me manage this rather than entrenching myself deeper and deeper into a system of referencing stuff I’ll never come back to. It’s just hard to fight that compulsion. I also don’t want to have one of those tumblrs that only reblogs. How do you guys keep your tumblr activity organized?
