Works great on IOS 9.3.5 in 2021
I'm autistic and sometimes can't speak, I have been nonverbal for a little less than a week straight right now and have used this app to communicate with my family and a few others. I am using the free version right now and love it. The voice is not the best but it works, and being able to program the buttons has been HUGE for me. I can only do three with the free version, I have yes, no, and ok. I have tried some apps I prefer on my phone but I definitely prefer to type on my iPad and this is the best app I found that supports 9.3.5. Once I get some money I will look into the not free version if I decide that this is still the best app for me. I'm planing on looking into some other free options with more buttons and see how I like that. I love this app, I would like more buttons and a better voice but other than that it's pretty perfect
