I would encourage just about anyone to try out Roger. It has a very pleasant UI, and in general, the quality is high. I wont pull down the rating for my concerns- I sincerely enjoy the experience. Some suggestions: Set the app apart from the voice messages within messaging applications. Make it more secure, easier use, easier to connect to- any and all of those things will attract users. Does the application include live conversations? As in truly live, back and forth? That genuine walkie-talkie feature would facilitate conversation that pushes the app past texting "with your voice"
