📝 About this app

Speech Assist Switch is an AAC app for people who are speech impaired and is designed to be used with iOS Switch Control. With Switch Control people with motor difficulties can operate their iPad with a switch.
The app has special features for scanning with iOS Switch Control like the option to adjust the scanning pattern and has page up/down navigation buttons to avoid scrolling.
If you don’t need these features, the original app ‘Speech Assistant AAC’ is the better choice.

Scanning pattern

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
