Each week PSFK features many new and innovative apps. To highlight the some of the best, we’ve compiled a roundup of the most interesting and creative apps written about on the site these past seven days:
An app for Android users lets Twitterers draw on their photos before tweeting them, or start drawing on a blank canvas. Twitter specially called out this feature as compatible with Samsung’s Galaxy Note 10.1-2014 Edition.

Zappix can replace traditional audio prompts from customer service hotlines, making it a lot easer to ask a question and get a response without the wait.
