While I love full featured apps, I always enjoy some simpler apps as well. Rapid is one of those simpler apps. Built using the Cascades framework and offering a native BlackBerry 10 experience Rapid brings quick sharing to Tumblr options to BlackBerry 10. Photos and text can be sent to Tumblr just by using the already built-in sharing options.
Have an image you want to send to Tumblr? No problem, just view it in your library and share it using Rapid. You'll have the option to add any captions you wish as well set whether or not it's a public, private or draft post. Additionally, you can add links, tags and if you have more than one Tumblr blog, choose which you wish to send to. The same applies for text as well. Just highlight it, share it to Rapid and send it off.
As I mentioned, it's a really simple app as it mostly just adds to the sharing menu more than anything else but sometimes that's all you really need. Rapid is available in BlackBerry World right now for only $.99. It's available for all BlackBerry 10 devices in all countries according to the BlackBerry World listing.
