An old friend of mine, Vic Douse, has a daughter, Jewel. She loves Disney, balloons, and some video games/apps. She has autism.
Vic is an Oracle DBA during the day, but at night, he has been very active in the autism community on PEI, serving as president of the Autism Society for years. (He won a Queen's Diamond Jubilee medal for his contributions).
Last winter, he started tinkering around with an Android app, despite not coding for years. The result is a simple memory/match game. The UX is... basic. But that's not the point: the point is that Jewel likes to play it. It helps her with her vocabulary.
So, check out Jewel's Audio Memory Game on the Play Store. It's free with no ads. Vic is delighted with each download, so give it a go. It's actually fun in a nostalgic way. My personal best for the 4x4 grid is 36 seconds, no doubt based on lucky strikes.
