Tumblr finally updated its mobile app to include a full theme editor, which makes Tumblr entirely transferrable as a platform between both mobile and desktop. Tumblr has had an app for about five years, but it has been notably missing a theme editor, which means that the true potential of the platform was only realized on computers. Updating both its iPhone and Android apps, the new editor provides the ability to edit the entire theme of blogs, from colors to layout, as well as letting users manipulate different aspects of their blog within a live preview. It means that international users who are used to mobile social networks will have an easier time with the platform, and that Tumblr’s adoption numbers could see a spike from broader, global adoption.
