Don't !!!!! ,


I downloaded this program but as soon as I try to use it crashed. I attempted to contact support but they don't exist. Don't waste your time.

Great update to a great app!

I babysit a child that's nonverbal so I've had this app for a long time and I've always loved it. I just updated it and wow!! The new look is really nice and even easier to use than before! If you're looking for an AAC app, this one has everything the super expensive ones do and you don't even need to pay to unlock more features.

Posco is just what I was looking for!

I've been trying out various AAC apps with a speech student of mine. He's mostly nonverbal but has some good cognitive skills and a lot he wants to communicate. I'd created a velcro picture book with him and love how versatile that is, so when I looked for AAC apps I wanted something equally versatile but with the advantages the iPad offers in voice output and easy organization. Posco has been a lot of fun to work with. The interface is simple and fun to use. My student caught on quite easily and it works well for him to build messages with a couple symbols: "I like" "soccer" for example. I've added the sections his picture book had - actions, people, school schedule, greetings, etc. - as folders. (I mostly removed the pictures and folders that came with the app, replacing them with images from that picture book). The developer is great, too. I proposed a couple ideas and he was super gracious and put out a recent update with these changes among others. So, definitely give this app some consideration and see if it meets your/your students' needs!
