Richard, you probably have to navigate to Play Store where the Google android apps are listed and search for apps. Read the reviews and decide to use a free one or a fee one.

My Google phone is stuffed full of things that Google put there and if I could I'd delete them. It is a single-core phone that they have sent out OS updates for to the point that it is now incredibly inefficient. The current OS is intended for dual core phones so mine labors to do anything. I can't go back to an earlier OS without hacking the phone but I don't know how to do that. I've moved stuff around to try to free it up, with little success. If you end up with too many apps in there you may want to evaluate and eliminate those you don't use much, or at all.
