Tumblr today released an updated version of its app for iPhone and iPad that allows users for the first time to customize the look and design of their blog directly from within the app. While you could always post and edit content to your blog from the app, the update means you’ll now be able to also edit your blog’s theme— change colors, fonts, pictures, etc— through the mobile app.

You now have total control over how your blog looks in the app. Colors, fonts, pictures, whatever—however you want to look, you can look that way. Download this thing and make your blog look amazing already.

You’ll be able to make changes to layout, color, font, etc through a WYSIWYG-style UI similar to on the web and also view a live preview of the changes before going live.

The update is available now on the App Store for iPhone and iPad users and also arrive for Android today.
