A. 1. Enable VoiceOver: Go to Settings > Accessibility > VoiceOver and turn it on. This feature reads out the text on the screen, making it easier for blind users to navigate the app. 2. Use Siri: You can ask Siri to open Bestgram or perform specific actions within the app, which can help navigate without needing to see the interface.

B. 3. Provide feedback: While I won't suggest contacting developers, consider using the app's feedback feature to suggest improvements for accessibility.
