Extremely Limited Uses

It’s great that users can put together sentences, but the voicing function only works for about 20 times before it starts saying “this is the free version of Sono Flex.” Only the quick phrases have unlimited uses, but those don’t cover many of the requesting/commenting needs we use. They do refill, but i need more than 20 uses for my students.

Pronouns

I’m disappointed in the lack of non-binary pronouns; they/them/their have been singular pronouns since the 1300’s!!!

Actually autistic! Works for me!

As an actually autistic particle aac user this app along with snap core first have been life savers. Very interested in the paid versions of both apps!

Maybe not the lite version

Buttons are cut off at the top on my iPhone 11 Pro Max. How do you get this app to speak aloud? Also why isn’t there a tutorial ?
