This is supposed to be more than a phone app. – Google Voice Review

It's not even close to being a phone app. You can do pretty much everything that you can do with a typical phone app but the user interface is just awful. To view recently placed calls or missed calls, is very very difficult and wierd. Make an overhaul of the app, not to do anything innovative, but just to make it look like a regular phone dialing app.
