Has potential – Green and Yellow Cab Review

I want this app to drive my business from the anti-taxi companies, I do. But it won't let me input addresses, doesn't update car gps & doesn't allow for charging to my card through the app (with the option to add tip if one could dream....). It doesn't search for locations when you try to do that, either. But you can book a cab without calling, and you can note that you'll be paying by card. So. Please, devs get it to work for real!
