Here is the part of the AAC conversation that rarely gets said plainly: you can put a working communication app in your child's hands today for zero dollars. Not a demo, not a crippled sample, a real symbol board that speaks. For a family waiting on an evaluation, stretching a budget, or simply unsure whether their child will take to symbol communication at all, free options are not a consolation prize. They are often the right first move.
But free is not the same as complete. The things free AAC apps tend to leave out are not flashy features. They are the quiet ones: someone to call when the app breaks, any record of how your child is actually using it, and confidence that the app will still exist in three years. This guide walks through the main free options honestly, then names those trade-offs so you can decide which ones matter for your family. If you are brand new to this world, our plain-language explainer on what AAC is is a better place to start.
Cboard: the open-source workhorse
If you only try one free AAC app, make it Cboard. It is a genuinely free, open-source (GPLv3) AAC application for people with speech and language impairments, built around picture symbols and text-to-speech. It runs in a web browser, and there are apps on both Google Play and the App Store. The symbols come from respected open libraries (Mulberry, ARASAAC, and Global Symbols), and language coverage is broad: the project's GitHub page says 40 languages, while the iOS listing says 33. Either number puts most paid apps to shame.
It is also actively maintained, which matters more than any feature. The iOS app shipped an update in December 2025, and the Android app has passed 100,000 downloads. This is not abandonware.
Now the honest part. Cboard's own pricing page shows what the free tier does not include: online neural voices, board sharing and publishing, copying tiles between boards, usage analytics, voice recording for tiles, export to the Open Board Format, a private support channel, and, notably, an ad-free experience. Those unlock with Cboard Pro at $8 USD per month or $79 USD per year, as of August 2026 (check the pricing page for current figures). Two of those gaps are worth underlining for parents. First, usage analytics, any record of how often and how your child uses the app, is a paid feature, not a free one. Second, the free experience is not listed as ad-free, which is worth knowing before you hand a device to a child. One more note for privacy-minded families: the iOS privacy label says the app collects usage data, crash diagnostics, and contact info (email and name), declared as not linked to your identity.
LetMeTalk: a free app, and a warning about longevity
LetMeTalk deserves its long-standing reputation as a generous free app. The iOS version is still free with no in-app purchases, offers more than 9,000 easy-to-understand ARASAAC images, and works entirely offline with no account required. For a family that needs basic symbol communication on an iPad today, it still functions.
It is also, by every visible signal, an abandoned project. The Google Play listing is gone entirely (the page returned a 404 when we checked in August 2026), and the app-tracking site AppBrain records it as unpublished from Play back in December 2021, with the last Android update all the way back in 2017. On iOS, the last real developer release was version 1.4.32 in August 2018; the only newer update is Apple's automated compatibility recompile. The official website was returning server errors when we checked. There is no reporting, no cloud backup, no multi-device sync, and, practically speaking, nobody left to email.
Why spend two paragraphs on a dying app? Because LetMeTalk is the clearest lesson in AAC longevity risk. Imagine spending months customizing boards and building your child's muscle memory for where every word lives, then watching the app stop working after an OS update, with no developer to fix it. Your child's vocabulary should not depend on a project no one maintains. Use LetMeTalk for a short-term need if it fits. Do not build your child's voice on it.
The free options already on your phone
On iPhone and iPad
Apple ships three relevant accessibility features at no cost, and it is important to be clear about what they are and are not.
- Live Speech (iOS 17 and later, iPhone XS or later) lets a user type what they want to say and have it spoken aloud, in person, on phone calls, and in FaceTime, with saved favorite phrases. For a literate child, teen, or adult who can type, this is genuinely excellent and completely free.
- Personal Voice (iPhone 12 or later on iOS 17 and up) creates a synthesized voice that sounds like the user, built from about 15 minutes of reading short prompts. Apple processes the recordings on the device, and if you sync the voice across devices, iCloud stores it with end-to-end encryption. It is designed for people at risk of losing their speech, so they can keep sounding like themselves.
- Assistive Access is a simplified iPhone mode for people with cognitive disabilities: bigger buttons, focused core apps. Useful, but it is a device mode, not a communication app.
The catch for most families reading this: none of these is a symbol board. They are built for people who can read and type. If your child is a nonspeaking four-year-old who communicates through pictures, Apple's built-ins do not cover that need, and none of them offers any kind of caregiver reporting.
On Android
Android has no built-in symbol-based communication board either, but Google offers two free downloads worth knowing about. Look to Speak (free, no ads, no in-app purchases, Android 9 and up) lets a user select pre-written phrases with their eyes, looking left, right, or up, and have the phone speak them. Google states that the eye-gaze data is processed on the device and never leaves the phone. It is built for people with motor and speech impairments who can read, and it is a phrase list, not a symbol vocabulary. Action Blocks (also free, no ads or purchases) puts picture buttons on the home screen that can speak custom phrases, aimed at people with cognitive disabilities. Three limitations from Google's own help page: it is not yet available for children's Google Accounts, it requires Google Assistant and an internet connection, and speech is limited to 7 languages. Neither app offers reporting of any kind.
Free trials of paid apps: the fourth free option
There is one more way to use serious AAC software for free: trial windows on paid apps. This category is underused, and it is uneven.
TouchChat handles it well. The separate TouchChat Discover app gives you a free 30-day trial of full TouchChat features. When it ends, you can buy TouchChat HD with WordPower ($299.99 USD, or $399.99 CAD on the Canadian App Store, as of August 2026) or keep using the free WordPower96 lite-tech boards, which is a genuinely decent consolation. PRC-Saltillo has also historically run half-price App Store sales; the spring 2026 sale ran in late April and early May.
Proloquo2Go, the best-known name in the category, offers no free trial at all. At $249.99 USD ($349.99 CAD) as of August 2026, that is a lot of money to spend on an app your child has never touched. AssistiveWare's only current discount is an education volume deal, 50% off for schools buying 20 or more copies. Prices in this category move around, so check the store listing before you budget.
The smart way to use trials: involve your child's SLP before you start the clock, pick a stretch of normal routine (not the week before a vacation), and treat the 30 days as a structured test of whether your child engages with the vocabulary. We cover this approach in more depth in our guide to choosing an AAC app, and the full cost landscape in our 2026 AAC pricing breakdown.
The free options at a glance
| Option | Cost | Best for | Biggest gap |
|---|---|---|---|
| Cboard | Free (Pro: $8 USD/mo) | A real symbol board on any device, dozens of languages | Analytics, support, and ad-free use are all paid |
| LetMeTalk | Free (iOS only now) | Basic offline symbol communication today | Effectively unmaintained since 2018 |
| Apple built-ins | Free | Literate users who can type (Live Speech, Personal Voice) | No symbol board, no reporting |
| Google Look to Speak / Action Blocks | Free | Phrase-based access, eye-gaze selection | No symbol vocabulary; Action Blocks excludes child accounts |
| Free trials of paid apps | Free for the window | Testing premium vocabularies (TouchChat Discover: 30 days) | Not all offer one; Proloquo2Go has no trial |
What you give up: support, reporting, longevity
Support. When a board glitches during a meltdown or a voice stops working after an update, free tiers leave you on your own. Cboard's private support channel is a Pro feature. LetMeTalk has no one left to answer. Apple and Google offer general device support, not AAC coaching. For many families this is fine until the one week it very much is not.
Reporting. None of the free options tells you how your child's communication is developing. Cboard locks usage analytics behind Pro, and the built-ins collect nothing you can see. Here is the nuance, though: this is not purely a free-versus-paid divide. Even Proloquo2Go, at $249.99 USD, has no usage logging or progress reports, and AssistiveWare says on its own blog that this is a deliberate privacy stance: they do not want a log of the exact words an AAC user has said. So the real question is not "does the app report" but "do you want reporting, and under what privacy terms." If weekly insight into your child's progress would change what you practice at home, or what you bring to an IEP meeting, that is a feature worth paying for from a company with a clear child-privacy posture.
Longevity. LetMeTalk shows how fast a free app can quietly die. Open-source projects like Cboard are more resilient because the code is public, but they still depend on small teams and uncertain funding. Ironically, the safest free bets for longevity are Apple's and Google's built-ins, which are also the least capable as AAC. The switching cost is real: hours of customization, and, far more important, your child's learned map of where every word lives.
A free app your child uses every day beats a perfect app you are still researching. Start somewhere. Just start with eyes open.
When free is genuinely the right call
- You are testing the waters. If you do not yet know whether your child will engage with symbol communication, Cboard answers that question for free.
- Your child can read and type. Live Speech on iPhone is excellent, free, and built by a company that will still exist in a decade.
- You are waiting on funding. If a school evaluation or insurance process for a dedicated device is underway, a free app bridges the gap without sinking money you may not need to spend.
- Your SLP already provides the tools in sessions and you only need light practice at home.
- The budget is simply not there. Cboard is a real AAC app. No family should feel their child's communication is second-rate because it runs on open-source software.
A middle path
Full disclosure: we make VoiceBloom, so weigh this paragraph accordingly. We built it for the family stuck between the free tier and the roughly $250 USD and up one-time apps: a symbol board for nonverbal and minimally verbal children on iOS, Android, and the web (Chromebooks included), with the things free options give up built in: weekly plain-language progress reports, a built-in coach, custom symbols, five languages, offline use, and actual humans answering support. It costs CA$19.99 per month or CA$199.99 per year as of August 2026 (see current pricing), and the 30-day free trial requires no credit card, so trying it costs exactly what Cboard costs: nothing. You can see how it works here. And if a free option already covers your child's needs, use the free option. We mean that.
Whatever you pick, pick something. Professional guidance, including ASHA's, is consistent on one point: early AAC use can help, not hinder, speech and language development, and the app on the tablet today does more good than the perfect app six months from now.
Frequently asked questions
Is there a completely free AAC app for a nonverbal child?
Yes. Cboard is free, open-source, and a real symbol-based AAC app with text-to-speech, symbols from ARASAAC, Mulberry, and Global Symbols, and support for 33 to 40 languages depending on the platform. Know the limits of the free tier, though: usage analytics, board sharing, voice recording, a support channel, and an ad-free experience all require Cboard Pro ($8 USD/month as of August 2026).
What happened to LetMeTalk? Is it still available?
LetMeTalk is gone from Google Play (the listing now returns a 404), and its official website was returning server errors when we checked in August 2026. The iOS version is still free to download and works fully offline, but its last real developer update was in 2018, so treat it as a short-term option, not a long-term plan for your child's vocabulary.
Does my iPhone have a built-in AAC app?
Not a symbol board. Apple's free accessibility features are aimed at people who can read and type: Live Speech speaks typed text aloud in person and on calls, and Personal Voice creates a synthesized voice that sounds like the user. Both are excellent for literate users. Assistive Access simplifies the whole phone but is not a communication app. None of them offers picture symbols or caregiver reporting.
Are free AAC apps good enough for my child?
Often, yes, especially at the start. A free app answers the most important early question, whether your child engages with symbol communication, at zero cost. What free apps consistently lack is support when something breaks, reporting on how communication is developing, and long-term certainty the app will keep working. Whether those gaps matter depends on your family, your SLP's involvement, and your budget.
Do expensive AAC apps like Proloquo2Go offer free trials?
It varies. Proloquo2Go ($249.99 USD / $349.99 CAD as of August 2026) offers no free trial at all. TouchChat does it better: the separate TouchChat Discover app gives a free 30-day trial of full TouchChat features, and you can keep free WordPower96 lite-tech boards afterward. Always check the store listing, since prices and promotions in this category change.
Can my child's school or SLP provide an AAC app for free?
Sometimes. Schools can evaluate a child for AAC and may provide a device or app through an IEP, and speech clinics often supply tools during sessions. Vendors also offer education pricing; AssistiveWare, for example, gives schools 50% off Proloquo2Go on purchases of 20 or more copies. If an evaluation is underway, a free app like Cboard is a sensible bridge while you wait.
