What fonts can be used in applications?

Question

Mobile development

Hello everyone, I'm designing an app for the first time. I would like to know which fonts can be used, and which categorically not? If, for example, I use paid ones, how will they be loaded?

Answer 1

Fonts are not loaded into the application online, you send font files (.ttf or .otf) to the developer, and he adds them to the project and uses them where necessary. You can choose any fonts you want without violating their terms of use (license).
