option to enlarge the source of the app

I humbly suggest you add an option to enlarge the app's letters for users who are visually impaired to use more comfortably and have a better experience in the app.

The issue does not name a file, screen, settings entry point, or test. Start by locating the app's settings and text-size or theme handling, then determine which screens should honor the option and how Android accessibility settings interact with it. Done means a user can enlarge the app's text consistently and the behavior is covered by appropriate checks.
