mobium accessibility

This tool on every surface: CLI · MCP · Python · JavaScript · Go · Java · .NET

Read the device's accessibility settings, or change one for the session

With no argument, prints every accessibility setting the device has. With a setting, prints that one; with a setting and a value, changes it, confirms it by reading it back, and puts it back as it was when the session ends.

Settings: reduce_motion, bold_text, increase_contrast, reduce_transparency, button_shapes, differentiate_without_color, invert_colors, grayscale, and text size — text_size (a category) on iOS, text_scale (a number) on Android. A switch takes "on" or "off". A platform that lacks one says so.

On a real iPhone, where nothing outside can change them, Mobium goes through the Settings app for the six switches and comes back to the app in front.
