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.
Capable of monitoring biorhythms like heart rate and temperature, Microsoft’s project Septimu aims to bring consumers a set of earbuds that can choose songs to cheer you up when you’re down. They’d work alongside an app developed with help from University of Virginia researchers.
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.
The app Key to the Street encourages people to connect with their communities by redesigning public spaces — doodling in playgrounds or adding greenery — and sharing their ideas with others.
Hashbag scans everyone’s Instagram feeds for the tag #forsale, and puts them all in once place on its site. You can now shop or sell your old things through the app.
