What is Big Font?

Big Font (change font size) – this tool will primarily be useful to people with vision problems, but those users who do not experience such difficulties, but are not satisfied with the standard font size settings, also have the opportunity to bypass system restrictions using this program. As a rule, the “Green Robot” settings allow you to select the font size from the options small, medium and large, that is, there are only three, and the capabilities of this program expand “horizons”, ranging from 20 to 1000% of the original value.

The preliminary result of changes made through Big Font (change font size) can be immediately seen in the preview window, which greatly simplifies the selection of the optimal option for the user. It is worth saying that the application changes not only the system inscriptions, the font is also enlarged in other third-party programs, for example, clients of social networks, instant messengers, online stores, and so on. The new product also has such a useful function as a magnifying glass – using the camera of your mobile device, you photograph, for example, small text, and then simply enlarge it to the desired size.

But this is not all the possibilities of Big Font (change font size), because in addition to the font, you can experiment with the size of application and folder icons, if necessary, downloading a suitable magnification factor from the network. Using this mobile tool thanks to its intuitive interface is incredibly easy, just select the appropriate font size and tap the “apply” button. The program does not require mandatory payments or subscriptions, but if you want to get rid of advertising, you will have to pay about three dollars.
