Could Android Switch Access Help With a Companion App?
Android Switch Access lets supported phone interfaces be navigated through switches instead of direct touchscreen interaction. It controls the phone interface; it is not a universal remote that pairs directly with a vibrator.
Understand the interaction
Google describes scanning that highlights items in turn until you select one. Compatible external switches or configured keyboards can provide the input. Follow Google's setup guidance and the switch manufacturer's instructions for your phone.
Check the app before buying hardware for it
A companion app may not expose every control in a useful way. Ask the developer whether its connection screen, settings and stop action have been tested with Switch Access. A general “Android compatible” label does not answer that accessibility question.
If you already have a suitable setup, inspect the app without a toy in use. Can scanning reach the correct control? Is the selection clearly identified? Can you exit a dialog without becoming stuck?
Account for the time to reach stop
Scanning through several items can take time. Before relying on it for a connected device, establish a documented stop method you can access promptly. Do not assume turning off a phone feature automatically stops the toy.
Ask for evidence, not a broad promise
For a Dear Tingle enquiry, describe the task you need to accomplish rather than sharing medical information: “I need to adjust and stop using switch scanning.” We do not claim that all manufacturer apps meet that requirement.
The manual-controls comparison can help identify another route if app navigation is unsuitable. An accessibility feature is useful when the complete task works, not just when the app opens.
