Want to use Android's Roboto Font? Check this post. Often we developers under-estimate the value that a proper font adds to the look and feel of our apps. We are usually OK with using the system font. The problem with doing this in a PhoneGap app is that the system font can look very different from one device to the next, heck it is can be different from one version of the operating system to the next, like the change from iOS 6 to 7. So simply depending on the system font may not be a good idea.
