Ever since Amazon opened up development for their Echo device, there have been a growing number of apps and devices added to Alexa's repertoire of features and functions. The latest interesting development is called the Roger App. This app is basically a conversational walkie-talkie style tool for your devices. It also lets you talk to Alexa through the app itself on your smartphone or tablet when you aren't in proximity of your Echo. The Roger App is available for Android or iOS, and is free to download. To be honest, the developer's website doesn't really describe the app all that well, but the app itself is pretty nifty regardless. Here's a link to Roger App site so you can check it out: RogerTalk.com.
