I recently took a deep dive into looking at inclusion of premade Kindergarten math, language arts, science, and social studies academic vocabulary in USA English in 23 vocabulary options in robust iOS symbol-based AAC apps.
✅ Here’s a ranking summary of how the vocabulary fared with inclusion of 147 specific wordson 3/15/25:
🥇 Proloquo (the newer app, different from Proloquo2Go): 147/147 = 100% (20 of the words are only available as a Related Word. So for those who are unable to use buttons that small or buttons without symbol support the score would drop to 127/147 but that’s still 1st place in this comparison)
🥈 PODD 60 Complex Syntax (same in all apps that offer PODD): 126/147 = 86%
🥉 Quick Core 112 in CoughDrop: 120/147 = 82%
SuperCore 50 Teen/Adult in Grid for iPad: 117/147 = 80%
Avaz 117 grid & Motor Plan 66in TD Snap (MP30 & MP40 have the same vocabulary as MP66): 116/147 = 79%
Speak for Yourself: 115/147 = 78%
Avaz 60 grid: 114/147 = 78%
SuperCore 50 Child in Grid for iPad: 108/147 = 73%
Full Vocabulary in LAMP Words for Life: 106/147 = 72%
Weave Chat AAC 7×15: 105/147 = 71%
9×16 Crescendo Advanced Core in Proloquo2Go: 104/147 = 71%
7×11 Crescendo Intermediate Core in Proloquo2Go: 102/147 = 69%
WordPower60 Basic & WordPower108 in TouchChat with WordPower: 100/147 = 68%
Talk Suite Pro 7×10: 99/147 = 67%
Flexspeak: 96/147 = 65%
Core First 8×10 in TD Snap: 94/147 = 64%
Quick Core 60 in CoughDrop: 85/147 = 58%
Gateway Developing Language & Gateway Advanced Communicator both 9×12 (really 9×11) in Proloquo2Go: 83/147 = 56%
Gateway Child Language and Literacy 9×11 grid in TD Snap: 80/147 = 54%
Note: The rankings in this comparison will change over timeas AAC app developers add new vocabulary to their app(s). Gateway in TouchChat with WordPower wasn’t included in the comparison since it doesn’t have a Search unless you edit to add it. Gateway in Mind Express 5 and WordPower in Grid 3 weren’t included in the comparison since those are only available on Windows.
❓How I decided on a list of 147 specific academic words:
I do NOT trust Artificial Intelligence (AI) to create accurate information and therefore did not use it when working on this comparison.
❓Where you can find a copy of the specific vocabulary list, data, and notes from my comparison:
This information is included in the most recent update for my Feature Matching Chart for the Top 13+ Robust iOS Symbol-Based AAC Apps on 3/15/25. Available on TPT: https://bit.ly/SymbolBasedAACapps. Those who have previously purchased this resource on TPT can download the newest version for no additional cost.
I will be emailing a copy to each of the AAC app developers included in this comparison.
❓How I determined if an app included these words:
This was based on a fresh install of the most current version of each app out of the box (official from that company, no editing done) on 3/15/25. Only included robust iOS symbol-based apps with a Search available. I personally checked all 147 words in all 23 vocabulary files in these apps.
❓Why my comparison is only for Kindergarten vocabulary:
I needed a manageable task to actually get it done. I don’t have access to an automated way to do this. It took me hours to search each word in all of these vocabulary options.
I have used Proloquo (the newer app, different from Proloquo2Go) enough to know the gap between the depth of academic vocabulary it offers vs. other AAC apps will widen even more as you look at academic vocabulary beyond Kindergarten. Proloquo offers academic vocabulary on up to an adult level.
❓Why my comparison is only for USA English vocabulary:
I am not a native or fluent speaker of any other language. Hopefully folks who speak other languages will do a similar comparison.
❓Why my comparison only includes symbol-based AAC:
Most Kindergarten students who use AAC tend to use symbol-based AAC. Of course some might be able to type or use text-based AAC… I’ve had kids as young as 3 1/2 years old who could…. but this isn’t typically the case.
⭐️ Conclusions:
The Proloquo app (newer app, different from Proloquo2Go) has excellent academic vocabulary but the half-sized Related Words buttons may pose accessibility issues for some individuals due to the small size and lack of symbol support. Hopefully AssistiveWare will eventually add this same depth of academic vocabulary to their Proloquo2Go app.
We need more AAC apps to come pre-programmed with robust academic vocabulary across grade levels that can be used by AAC users with a wide range of access needs.
Relying too heavily or solely on “descriptive teaching / descriptive language” will not allow individuals access to enough vocabulary to be successful in academic settings. This is feedback that I’m hearing directly from AAC users and those supporting them. Having more academic vocabulary pre-programmed will reduce the burden currently put on parents and/or AAC users to add this. I’ve personally experienced folks taking “descriptive language” to an extreme when I questioned why particular commonly used words weren’t in an AAC apps. In one instance I was told to use “round + sandwich” when the word “hamburger” wasn’t in an app. That happened to be one of that child’s favorite foods so of course I added that word.
✅ ❌ Important Notes:
Of course we can’t expect an AAC app to have EVERY word in the English language. Even Proloquo doesn’t have EVERY word and I see occasional posts from folks asking for advice on where to add a particular word or related word. Every AAC app is going to need to be personalized. That’s different from the academic vocabulary being discussed here.
I am NOT implying these are the only academic words a Kindergarten student might need. That might vary depending from state to state and from school district to school district.
I am NOT implying that AAC use should become “work” or used primarily for “academic” activities.
I am NOT implying that these 147 words are only “academic”. Words are words. They might be used to share information about highly preferred topics and used across environments (not just at school).
This is just a comparison of one aspect out of hundreds of features in robust AAC apps. It should not be the only thing considered when considering AAC options. It’s important to do comprehensive feature matching and a consideration of all of the things that individual might need in a robust AAC system (which often needs to include more than one tool). See my roundup post of in-depth Feature Matching Resources for AAC Apps (comparing features in AAC apps) + several videos comparing AAC apps across platforms (iPad, Android, Amazon Fire, Windows):https://bit.ly/5aacFeatureMatchingResources
I’m NOT saying that Descriptive Teaching / Descriptive Language isn’t a helpful strategy. But I am listening to AAC users and parents supporting them when they express frustration in how that is often used as an excuse to not provide enough academic vocabulary in AAC apps for them/their child to have access to enough vocabulary to be successful in academic settings.
Two things can be true at the same time. It will be helpful to have more academic vocabulary included in symbol-based AAC apps AND “descriptive teaching / descriptive language” strategies can be helpful when a particular word isn’t available in that particular AAC app yet.
🎯 The purpose of this comparison is to raise awareness of robust academic vocabulary needing to be included as part of an AAC system/toolkit. See this blog post for more info: https://bit.ly/DearAAC-appDevelopers.

Weave Chat AAC has added quite a bit more content and features and is now a robust AAC app that’s totally free. They offer apps on three major app stores: iOS, Google Play (Android) & Amazon.
How to add high quality Acapela voices to Android AAC apps
Want basic info about this app? Check out “Affordable and Free AAC apps & AAC-Related Apps (iOS, Android, Amazon Fire, Windows & a few web-based options)”: https://bit.ly/BasicAffordableAACchart.
Want an in-depth look at the Android and Amazon Fire versions of Weave Chat AAC? Check out this expanded resource: “Feature Matching Chart for Robust Android AAC Apps (Google Play & Amazon Fire)”: https://bit.ly/RobustAndroidAACappChart.
Updated this blog post on 8/12/23: That Android phone is still available on Amazon and is even a little less expensive now ($49.88). The case is still also available and is less expensive ($11.99). If you put the free Android version of Weave Chat AAC on it (https://play.google.com/store/apps/details?id=com.weavechat.weavechat) you can have fairly robust pocket-sized symbol-based AAC for under $62 (+tax). The adult text-to-speech voices from Samsung & Google are pretty good. If you want Acapela voices, the Weave Chat AAC app and a few others allow use of the one you have purchased and set as a default within the Acapela app. That would be a way to add high quality child voices. Prices vary. I just purchased the child African American English voices (Tiana and Malik) for $7.99 each. The great thing is you only have to purchase the Acapela voices once and then can use them in any AAC app that supports use of them. I have previously purchased Ella & Josh (USA English) + Valeria & Emilio (USA Spanish). That app has voices available to purchase in several languages.
So for under $70 (+tax) you can have fairly robust pocket-sized symbol-based AAC with Weave Chat AAC using a high quality Acapela voice.
