Interesting iOS usability testing library from Gabriel Handford. Capture the screen, interactions, video and audio while someone uses your app and then play it back later to see how they struggled (or didn't). This is obviously a well established technique but this is the first implementation I have seen of it on iOS.
We released this little utility yesterday to help replace the status bar on your iOS App Store screenshots with a clean, perfect version. No carrier text, 9:41AM time, full battery, etc... I always tried to clean up the status bar before submitting our screenshots but I got a little tired of doing it manually in Photoshop every time so we produced a little tool to help us automate the task. Full disclosure: This tool was written by my company.
