Perpetual underdog Mobli, an app that’s a cross between Instagram and Vine, has released a new update to its iOS app in their latest effort to gain some of the photo sharing market. The new update contains a plethora of features, such as a new aggregated feed and location-based photo filters, but the app’s most notable update is its newfound ability to switch back and forth between the front and back facing cameras of your smartphone while recording. In practice, it works pretty well. Although there’s a one second lag when you switch between cameras, the recorded video plays back seamlessly and I imagine it could be used for some great reaction videos. It’s a very simple feature that hasn’t been implemented in any other video recording apps yet (including the stock camera apps in iOS and Android), although I would expect all of them to follow suit pretty soon. It’s also a little like the dual camera feature that was showcased in Samsung’s Galaxy S4 event, which allowed you to use both cameras simultaneously while recording video. Somehow this simple feature of switching back and forth seems a little more practical than seeing your face boxed into a stamp next to whatever it is that you’re recording. The update is available in the Apple App Store now.
