Some apps don't need much explanation. Sidewalk Buddy is one of those apps... but I'm going to explain it anyway. So, as everyone knows, attempting to chat or text on your phone as you walk on a busy city street is a great way to make people hate you. It's also a great way to bump into someone and drop your phone. But a lot of us still do it from time to time, because it seems like a good idea - and it's so efficient! I personally give up on either the walking or texting part after the first pedestrian-on-pedestrian collision, but Sidewalk Buddy may finally be the solution we've all been looking for.

I mean, if the picture above doesn't give you the gist, I'm not sure I could actually write it out any better. It's a floating app that feeds live video from your rear camera, so you're able to see who or what is coming into your path while your head is firmly fixed in its "don't talk to me, I'm busy on my phone" position. It's actually a pretty great idea.

You can adjust the size of the video window, level of digital zoom, and even use a custom aspect ratio, should you so desire. The app is compatible with most phones and tablets that have rear cameras.
