Built on great work.

ShoutAbout is free, but its own code isn't open source. It stands on open-source software, models and fonts. Thank you to everyone who made them.

Full licence texts come with the apps. On Windows: THIRD-PARTY-NOTICES.txt in the install folder (usually C:\Program Files\ShoutAbout), generated from exactly what each version ships. On iPhone: Settings › Font licenses.
