Blogsy: This gem is a must for Bloggers everywhere. It is compatible with Blogger, Wordpress, Tumblr, and more. This $4.99 app is worth every penny because of it's ease of use. What makes it even more fun is that you can draft your post offline and post it either in draft (unpublished) or scheduled. One of the best things is that you can associate multiple accounts, which is great for the majority of Bloggers who have more than one blog. It automatically saves not only the post, but in the exact spot you left off. How convenient is that?
