Hi Marc;

    FYI: https://docs.appeon.com/appeon_online_help/ps2020/development_guidelines/Control_font.html

    FWIW:  Personally (like in native PB Apps), I have been using Tahoma 8 point as my standard for over a decade now - including my PS Apps. That seems to render just nice on my Android and IOS devices as well.

HTH

Regards ... Chris
