Back when Nextel was still alive and kicking, and all you heard was the push to talk noise wherever you went I was jealous. I thought it would be great to have one of those phones and be able to connect so quickly. With this app I am able to have a bit of that dream. The user interface is pretty great, but it could use a little help in the connection area. It's a bit sketchy when it comes to connecting and staying connected. I would also like to see the ability to keep your phone from falling asleep while in a "call". All in all it's an awesome app.
