If you enjoy chatting with a group of friends or family then Roger is for you. I describe the app as something like using a CB radio, but more modern. The app allows for unlimited recording/chat time. It also allows for connecting with popular services such as, Dropbox, Facebook and Twitter just to name a few. The sound quality of the app is quite clear and easy to hear. More importantly, its fun and simple to use. Its free to download in both the App Store and the Google Play store. A awesome tool for communicating on the go.
