A new app to hit the iOS App Store and Google Play is Sidecar. The service is essentially a phone service with a little something extra. When you’re on the phone and something is happening outside your bedroom window or in the coffee shop you’re sitting in, you usually have to describe what’s happening in front of you only with words. The app wants to let you send video or photos of what’s happening in front of you to the person you’re on the phone with. Within the United States and Canada, Sidecar allows its users to call non-Sidecar users for free and outside those two countries, you can call anywhere in the world for free, as long as your call recipient is a Sidecar user. Like FaceTime, however, the app will only let you call over Wi-Fi, which, while on the one hand will save you data bill shocks, on the other doesn’t allow you to send the person you’re talking to any media of what might be happening, while you’re walking on the street. Of course, for the latter purpose, you can just take video on your phone and upload to Instagram and Socialcam (or any other social network of your choice).
