Ballyland Sound Match

My son has CVI, educationally legally deafblind, age 11 with multiple physical handicaps. I was hoping the app would be slightly more inclusive. He generally uses apps geared toward ages 2-5 with specific traits. I’m looking for inclusive apps that are self-correcting with no negative reinforcements (error sounds) because my son tends to self-stimulate and has difficulty with compulsive light gazing (CVI) and auditory processing deficit as result of early hearing loss & seizures. Also no background music 🎶 is better than background music that can’t be shut off or volume adjusted... just some ideas for developers out there. I would love to beta test new apps so please reply here if you’re interested for future updates!
