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.
Open-source and volunteer-built free apps
There is a small ecosystem of genuinely free symbol apps, most of them open source or volunteer built, available on the web and in both app stores. The best of them are real AAC: picture symbols from respected open libraries, text-to-speech, and broad language coverage. For testing whether symbol communication clicks for your child before spending anything, they are a legitimate option, and no family should feel their child's communication is second-rate because it runs on free software.
Read the fine print before you commit, though. Across this category, the same catches repeat. The features parents end up wanting most, usage analytics, board sharing, a support channel, and often an ad-free experience, tend to sit behind a paid tier. Privacy postures vary and are worth checking on the store listing. And maintenance is the biggest wildcard: these projects depend on small teams and uncertain funding, and free AAC apps have a history of quietly going unmaintained, taking months of board customization and your child's learned muscle memory with them when they break.
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 |
|---|---|---|---|
| Open-source symbol apps | Free (paid tiers vary) | Testing symbol communication at zero cost | Analytics, support, and ad-free use are usually paid; longevity varies |
| 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. Across the free category, a private support channel is typically a paid feature, and volunteer projects may have nobody left to answer at all. 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. Free tiers typically lock usage analytics behind a paid upgrade, 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. Free apps can quietly die: one long-popular free AAC app has been effectively unmaintained since 2018 and has already vanished from Google Play. Open-source projects 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, a free symbol app answers that question at no cost.
- 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. Free symbol apps are real AAC. Communication now beats a perfect app later, whatever it runs on.
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, nine 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 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. Free, open-source symbol apps with real communication boards and text-to-speech exist on the web and in both app stores. Know the limits of a free tier before you commit, though: usage analytics, board sharing, a support channel, and an ad-free experience usually require a paid upgrade, and long-term maintenance varies by project.
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 symbol app is a sensible bridge while you wait.
