Should Ionic Material include Roboto fonts adding ~13MB to your project VS Ensuring fonts available for iOS Material Design?
Latest versions of Android include Roboto as the system san serif, older versions do not.
iOS doesn’t include Roboto but has San Francisco which has similar glyphs and typographic styles.
The Material Design guidelines for typography states Roboto should be used, however the implication is a larger app size due to including the font.
Really useful to know that the font isn’t required for android by I would argue that whether it is included or not for iOS is irrelevant as in my opinion you shouldn’t be using Google’s material design on that platform.
I think it’s fine to take inspiration from the concept but re-implementing with the same or similar fonts etc is not appropriate.
