Variable Font Test

The Variable Font Test application is a versatile tool designed to cater to users with an interest in typography, offering the ability to experiment with variable fonts and their features directly on Android devices.

This app provides access to basic settings such as adjusting the font size and selecting various font families. The custom font feature enables the selection of fonts through a file manager and even supports OpenType collection (.TTC) fonts.

An impressive aspect of Variable Font Test is its font variation capabilities, enabling users to delve into the intricacies of typography by manipulating axes like italics (ital), optical size (opsz), slant (slnt), width (wdth), and weight (wght). Additionally, you are not limited to built-in axes, as the program allows you to add more through a user-friendly interface or by inputting your specific criteria via text.

Font features are also extensively covered, with built-in support for character width (chws). Like the variation axes, these features can be expanded according to user preferences through the user interface or text commands.

Variable Font Test is ideal for those looking to explore the full potential of variable fonts on Android devices and is distributed under the GPLv3, ensuring freedom in software usage and distribution.
