Big Font — System Font Resizer & Magnifier
Big Font lets you adjust the system font size on Android devices, offering scaling from 25% up to 500%. The app also provides display scaling options and, on supported devices running Android 12 or later, the ability to change system text weight to bold or thin.
Features
Adjust system font size between 25% and 500% to improve readability across apps and menus. Display scaling options help you modify overall UI size where supported.
Use the camera zoom, autofocus, and LED flash to turn your device into a handy magnifier for reading small print. A live preview shows how text will look before you apply changes.
A notification icon can indicate the current font size with an option to hide the icon. The PRO version removes ads and unlocks additional features and settings.
Compatibility: Some features require Android 12 or later and may vary by device manufacturer. The app will request only the permissions necessary for its features (camera for magnifier, system settings for font and display changes).
