Re: There is an application for Apple Watch to alert you when your iPhone is not in range With it
There is the stock ping feature. If you swipe up from your watchface, the left most screen with your settings on it, there's a control on the bottom left side with a picture of an iPhone. Tap it and it will make your iPhone make a tone. Long press it and you'll get the tone plus flashing LED. There's also find my iPhone if that's enabled on the iPhone. I'm not sure there's an app that you can download to track your iPhone from your watch though. I haven't looked into it.
