Which type of PowerApps allows the use of screen readers without special connectors?

Model-driven PowerApps are designed with accessibility in mind and inherently support the use of screen readers without the need for additional connectors. This is primarily because model-driven apps utilize standardized components that follow best practices for accessibility, making them easily interpretable by assistive technologies like screen readers.

These apps derive their structure from the underlying data model, allowing users to interact with the data in a familiar and intuitive way while ensuring that the interface is accessible. As a result, users who rely on screen readers can navigate through the application effectively to access the functionality and data they need.

Canvas PowerApps, while customizable, may not always be structured in a way that supports screen reader compatibility due to their flexibility in design. They allow for a high degree of customization which can sometimes lead to accessibility challenges if not designed with accessibility features in mind.

Given this context, the assertion that only model-driven PowerApps support screen readers without special connectors is accurate, as they are built with accessibility principles integrated into their framework.
