Please read the entire description. TypeFace needs specific requirements for it to work on your device.

With TypeFace all Google Web Fonts are just a click away for use with Cyanogen Theme Engine or Substratum! Generate font themes on the fly by downloading fonts available on Google Fonts (http://fonts.google.com). For the power user, TypeFace also provides a premium/paid option for creating font themes by importing fonts from archives (ZIP/APK) or font files (TTF/OTF).

TypeFace works on:
1. Rooted ROMs (Known issues: Box symbols at some places, Read here for more info: https://goo.gl/ZMhHJR)
2. A custom ROM with Cyanogen's Theme Engine (CM14/LineageOS doesn't have a theme engine)
3. A custom ROM with OMS support. Substratum app alone is not enough for font themes to work.

Note: Andromeda based theming does NOT support fonts replacing. Check here:
