My favorite AAC program

For me, this app is well worth the cost. The program is more customizable than any other that I have used, and the prediction buttons are very, very helpful. The symbols are of great quality, and I love that you can change the colors to suit your preferences. The voices are very clear and not as awkward-sounding as some other text-to-speech options. I would highly recommend this app to anyone with complex communication needs. Also, it is about a quarter of the price that most AAC apps sell for, and does not require a subscription.

Sometimes if I am editing a lot, the program will crash, but I only lose the changes to the last button I was editing, so it is just a small inconvenience.

I like it (an autistic user)

I like the app and how it’s fully customizable to my liking. I use it here and there. I like how it’s only 50 bucks, not too expensive. I’ve used this app for a year now and I’ve come to love it. I’m learning new languages along with being able to organize my thoughts. I made my own homepage, modeled after someone else’s. I’ve recommended TD snap to almost everyone I’ve come in contact with. I want to try P2Go, but it’s too expensive for me, so I’ll stick to m6TD snap. I am considering Gateway but it’s way past my budget and I’ve already done the trial, so I’ll stick to the regular set.

Autism acceptance ,

One of the best!

First of all, I’d like to start out with letting you know that I am in no means a speech language pathologist and this is purely my opinion. I am just a semi-verbal autistic looking for the right app. I started using AAC about a year ago. Back then, I wasn’t sure if it was for me. Before buying this app I highly recommend trying out a free app such as “I can communicate” (android) or “let me talk” (iOS) it might be a little strange or difficult at first but if you like it after a while, this could be a great purchase for you. It’s incredibly customizable. Especially for people with not just vocal apraxia but other motor disabilities that limit their ability to accurately press small buttons. The snap core first page set can really accommodate to almost any disability or age group. So this is something that you could start using at age 4 and continue using it into adulthood if necessary. I have tried MANY other AAC programs and while I found some really good ones, this is on another level. It is so easy for the user to communicate with a large vocabulary. I now easily use the largest grid size which was really challenging for me in other programs. I’ve used other programs in which the AAC felt very limiting. I could say what I wanted and what I needed but I couldn’t really have a full conversation with someone the way neurotypicals could. Now I can. I think another really important thing to realize, is that just because a disabled person is verbal, doesn’t mean they don’t struggle with communication. Some people forget their words or they just don’t know how to properly create a sentence. Some people struggle with stuttering. Some can speak perfectly but don’t really understand the meaning of their words. This program helps with that and more. If you are the caregiver or parent of someone with a disability, this program is definitely worth a try. You can use the built in keyboard to help teach your communicator to read, and also show them social stories. You can teach them how to set timers and wait patiently and even make a script for the communicator so they can understand how to properly participate in a conversation and what is usually expected of them to say. And if your communicator isn’t ready for a full on conversation, that’s ok. There are plenty of ways to customize this to be as simple as you need and work from there. There’s a particular acsessability setting in which you can pick how long the button has to be pressed in order to work. This is a game changer for many people who are always pressing the wrong buttons by accident .You can even choose how long you want to hold down the button before it speaks. If you need a bit of help with accuracy there is also an option to highlight the button when pressed so you can be assured which one you are pressing. (And so much more) The colors changing abilities are also so exciting to me. As a sensory seeking person, colors are awesome. If your communicator is uninterested, make some special pages for them with their favorite colors and pictures. If your communicator is sensory avoiding, no problem. Different Greys and blacks will work great too. Another thing, there are tons of YouTube tutorials made by the Tobii dynovox company that really go in depth of all the settings and techniques. If you need a little help getting started, search up the tobii dynovox channel on YouTube. And I get it, the price might make this app a little off putting at first, but in my opinion, monthly subscriptions are worse in the long run. This is a one time purchase and done. If you are a caretaker of someone in school who needs this, you can also try to request an IEP meeting. Usually the district will be able to cover the cost if they understand why your communicator might need this. keep advocating for yourself or your communicator, and good luck on your AAC journey.
