I created a website for my mom, who is an aphasic, it helps her tap out simple social messages and sends them via email to friends and family members. It helps because I get updates throughout the day, then, when I see her later, I have a context to begin our conversation. I made it free and open for anyone. http://www.tapgram.com
It’s useful for anyone who has trouble with keyboards, articulation, typing, and many other challenges.
