Truthfully the Xkit iOS app (see xkit-mobile for more details) is useful at clearing up the Tumblr noise (mute feature would be handy in hiding posts that are reblogged too much by friends) as well as implementing safe mode (although I do not follow any porn blogs here).
However those are the only major advantages of using the premium app (it’s $1.99 USD on iTunes) over the official Tumblr App for iOS.
Unlike the official Tumblr app, the Xkit app:
- Can not upload multiple pictures within one post
- Is unable to share post to alternative mobile browsers (like Google Chrome)
- Does not support Tumblr @ mentions
- Does not support Markdown (it’s coming to Xkit, but if you’re a geek like me then this isn’t important)
Aside from that Xkit is a great iOS App for Tumblr but until then I’ll use the official app! :-)
