You were always jealous of this cool new font Google introduced with Ice Cream Sandwich? “Roboto“ is available to everyone with this application. Google’s self-developed font probably offers one of the best readability-expierences in the mobile OS – world. But not only that font, which was extremely hyped, can be applied with this application. Several hundreds are available including a preview of them. Even your own fonts can be installed – a big plus for that! However, for such a deep invasion in the operating system, the application needs root-access. This means your device has to be rooted (Take attention: This usually voids your warranty!).
Furthermore, a really positive aspect of this free application is, that it won’t ask you for doubious rights, but always keep in mind: An application with root-access can always harm your device. However, it didn’t do that for me ’til now.
All in all, a great application for fans of fonts! (FFOF!)
4 out of 5 points. Although I usually like minimalistic user interfaces, this one could use some polish. Download it here for free! (at the official Android Marketplace)
