The original purpose of cellphones was to make it possible for a person to use a phone no matter where he was. As you know, the device has evolved into something more. But where its other capabilities have moved forward, the calling feature remains pretty much the same. Until now.
Sidecar is an app that takes everything great about a smartphone and uses it to make calls better.
For instance, an intuitive feature called “smart calling” automatically puts a call on speaker if the phone is pulled away from the talker's face.
If the caller would like to share his location or what he's seeing, he can activate the “see what I see” feature. This could be useful in situations where the callers needs to show the person on the other end of the line what he's seeing and still talk in real time — like when shopping for a gift for a mutual friend.
Information passed along during conversations is saved in the history even after the call has ended. That includes IMs sent when utilizing the "whisper" feature, which lets users message during a call if there is a lot of background noise.
Both callers need to have Sidecar to access these features, but if a call has to be made to someone who doesn’t have it, it can be done as a voice-call only. The app is free and available for Android and Apple devices in the United States and Canada.
