My 14yo grandson is autistic and has several other severe learning disabilities.
I got him an LG trac-phone for his birthday hoping it will help with his communication skills...his cheap LG phone has audio message so he can send his texts without trying to type them....since he can barely read.
Now my Iphone 7plus...a little more expensive

does not have, or at least I can't find the same feature so I can send him audio messages....I do have the microphone with my text message but that just types my message....Is there an app I need to get? or am I just not finding it...
Help please
