Last updated 2026-08-10 | By Little Words Editorial | How we check our work
Process note: we opened every app listing and publisher page named below on August 10, 2026, and re-checked each free tier, price, offline claim, and update date against that source. Nothing here is quoted from other roundups.
Quick answer: Four free options are genuinely usable with a toddler today: Cboard, an open source app with no paid tier; AbleNet's SoundingBoard, free with 20-location boards; Expressive Go's free tier of six speaking screens; and TouchChat HD Lite as a paid-app preview. LetMeTalk is free but has not been updated since 2018. Every fact here was re-checked against the stores and publishers on August 10, 2026.
What is AAC, and does it help toddlers communicate?
AAC stands for augmentative and alternative communication: picture boards, speech-generating apps, signs, and gestures that let a child communicate beyond spoken words. ASHA defines AAC as an area of practice that "supplements or compensates for impairments in speech-language production and/or comprehension." [1] For a toddler with little or no speech, an AAC app offers a way to request, refuse, and comment right now, instead of waiting on speech alone.
The worry most parents bring to this page is whether a talking app teaches a child not to talk. The evidence points the other way. ASHA's AAC Practice Portal states that "AAC use may help improve natural speech when used in a multimodal approach." [1] Our explainer on whether AAC stops a child from talking unpacks that research in parent terms.
If your child is under three and not yet in services, start the early intervention process in parallel. IDEA Part C funds early intervention programs in every state, and an evaluation there can bring an SLP into the app decision at no cost to you. [2]
Which free AAC apps are actually worth trying in 2026?
Here is the free-tier truth for every app we could verify against its own store listing or publisher page on August 10, 2026. "Free" claims in AAC roundups go stale fast, so each row names exactly what costs nothing.
| App | What is actually free | Offline | Ads and purchases | Watch out for |
|---|---|---|---|---|
| Cboard (web, Android, iOS, Windows) | Everything; free software under the GPL v3 license, using Mulberry, ARASAAC, and Global Symbols sets, in 40 languages | Loads from local cache after first use via a service worker; full function is best with a connection | No paid tier | Voice quality depends on your device's built-in speech synthesis |
| SoundingBoard (iOS, by AbleNet) | The app; boards with up to 20 message locations using AbleNet symbols or your own photos | Recorded-message boards live on the device | Free, with add-on board packs currently listed at $0.00 | Recorded voice only; 20 locations is a ceiling for a growing communicator |
| Expressive Go (iOS, by Smarty Ears) | "Six fully functional speech-generating screens at no cost," per the publisher | Not stated by the publisher | Full symbol library requires $9.99 per month, $49 per year, or $89 lifetime | The free tier is a real starter, not the full 30,000-symbol library |
| TouchChat HD Lite (iOS) | A limited preview version of TouchChat HD | TouchChat vocabularies run on the device | The full app is $149.99 plus tax | Treat the Lite version as an evaluation copy, not a long-term system |
| LetMeTalk (iOS) | The whole app; ARASAAC library with more than 9,000 images; "no internet connection or mobile contract is necessary" | Yes, fully offline by design | Free; no purchases listed | Last updated August 20, 2018, and its US Google Play listing was gone when we checked; assume no support |
One deliberate omission: earlier versions of this article, and several roundups still ranking today, recommend free AAC apps that no longer exist or never shipped. We removed anything we could not open in a store listing on the check date. If an app you are researching is missing here, that may be why.
What makes Cboard the strongest fully free starting point?
Cboard is the only option here with no paid tier at all: it is free software under the GNU GPL v3, it runs in a browser as well as on Android, iOS, and Windows, and it supports 40 languages. [3] It draws on three open symbol sets, Mulberry, ARASAAC, and Global Symbols, and it has real-world deployment history through UNICEF's "For every child, a voice" project, which distributed the Cboard Communicator to children who needed AAC. [3]
For a toddler, the setting that matters most is grid size. Shrink the board to a handful of large cells; a two-year-old's finger accuracy cannot handle a dense grid, and a wall of symbols buries the words that matter. Start small, then grow the grid as your child's accuracy and vocabulary grow. Our guide to what vocabulary to put on an AAC device first gives a starter word list that fits a small grid.
Two honest limits. Speech output uses your device's built-in synthesis, so voices sound robotic on older hardware. And while a service worker lets Cboard load from local cache after the first visit, it is a web-first app, so families with unreliable internet should test it in airplane mode before relying on it. [3]
Is LetMeTalk still a safe recommendation?
Only with open eyes. The good: LetMeTalk is genuinely free, builds sentences PECS-style from ARASAAC pictograms, ships "more than 9,000 easy to understand images," and works with no internet connection at all. [4]
The bad: its iOS listing shows a last update of August 20, 2018, and when we checked on August 10, 2026, its US Google Play listing was no longer available. [4] An eight-year-old app can stop working with any OS update, and there is no sign of active support. If you already use it and it works, fine. If you are starting fresh, start with Cboard or SoundingBoard instead, and treat LetMeTalk as a fallback for older Apple devices.
What about SoundingBoard and Expressive Go?
SoundingBoard is AbleNet's free iOS app. You build boards of up to 20 message locations using AbleNet's symbol library or your own photos, and you record the voice yourself. [5] That recorded-voice design is a quiet advantage with toddlers: a familiar voice saying "more" often lands better than synthetic speech. It pairs naturally with AbleNet's hardware world; our AbleNet device guide covers how the app fits beside the $155 BIGmack and its siblings.
Expressive Go, from speech-app maker Smarty Ears, gives "six fully functional speech-generating screens at no cost," with the full library of more than 30,000 symbols behind a subscription of $9.99 per month, $49 per year, or $89 lifetime, as listed by the publisher on August 10, 2026. [6] Six free screens is enough to test whether symbol-based requesting clicks with your toddler before any money changes hands. That test is the whole point of a free tier.
How do you set up a free AAC app so it actually works?
Setup decides more than app choice does. Three rules carry most of the weight:
- Start with a handful of powerful words. ASHA describes core vocabulary as "high-frequency words that make up about 80% of the words used by most people every day." [1] Words like more, help, stop, and go, plus two or three favorites, beat a 60-symbol board on day one.
- Model it yourself. Tap the symbol while you say the word, during real moments, without demanding anything back. ASHA frames AAC as multimodal practice, and partner modeling is the engine of it. [1] Our walkthrough on modeling AAC shows what this looks like at the snack table.
- Keep the tablet reachable and locked to the app. A communication tool in a drawer is not a communication tool. On an iPad, Guided Access keeps a toddler inside the AAC app; our guide to locking down an iPad for an AAC user has the exact settings.
When is a free app enough, and when should you pursue a funded device?
A free app is enough when it is being modeled daily, the child is adding symbols, and the hardware you own survives toddler life. Plenty of families run on this happily for a long time.
Pursue a funded system when any of these is true: the child's vocabulary needs outgrow the free tier; motor access needs (switches, eye gaze, key guards) exceed what a consumer tablet does; or the family cannot supply a dedicated tablet at all. Two funding lanes exist, and they are different:
| Route | Price and funding | Access and eligibility | When not to choose it |
|---|---|---|---|
| Free app on your own tablet | $0 software; you supply the hardware | Start today; no evaluation required, though an SLP's input sharply improves setup | Not durable or fundable as medical equipment; Medicare-class SGD benefits exclude consumer tablets [7] |
| Paid app on your own tablet | TouchChat HD $149.99 plus tax; Proloquo2Go $299.99, no free trial (both checked 2026-08-10) | Buy once through the App Store; deep vocabularies and support | Do not buy before trying free tiers and, ideally, an SLP-guided trial |
| School-provided device | No cost to the family; provided by the district | IDEA regulations require public agencies to make assistive technology available when the IEP or IFSP team documents the need [2] | Device usually stays school property and may not travel home; push for home-use language in the plan |
| Insurance-funded dedicated device | Billed to Medicaid, Medicare, or private plans as durable medical equipment [7] | Requires an SLP evaluation and documentation; the device belongs to the child | Slowest path; do not wait for it to begin communication practice with a free app now |
Our school AAC guide covers the IEP route step by step, and the free AAC device guide covers loaner libraries and grant programs between those lanes.
Can you use a free AAC app without a speech therapist?
You can start one today without anyone's permission, and you should not wait to give your child a way to request and refuse. Still, ASHA is clear that SLPs "play a central role in the screening, assessment, diagnosis, and treatment" of people who need AAC, and an SLP will catch setup problems a parent cannot see, like a grid size that fights the child's motor accuracy. [1] If weekly therapy is out of reach, even a one-time AAC consult moves the setup a long way. Under age three, the free early intervention evaluation is the front door. [2]
Are there privacy concerns with free AAC apps for kids?
Ask two questions of any app your child uses: what does it collect, and where does it run. On the collection side, the FTC's COPPA rule restricts what commercial apps may collect from children under 13, and a children's app with no account requirement and offline function leaves the least surface area. [8] LetMeTalk's fully offline design and Cboard's open source code are both easy to reason about; for commercial apps, read the current privacy policy rather than an old review, because policies change with updates.
What this page can and cannot tell you
This page can tell you what is verifiably free today, what each free tier actually contains, and when the funded-device lanes beat any app. It cannot tell you which system fits your child's motor skills, symbol understanding, and language profile. That is an AAC evaluation question for a speech-language pathologist, and no list, including this one, replaces it. [1]
Little Words is a speech practice app, not an AAC system, and practice tools supplement therapy rather than replace it. If you are sorting out where each tool belongs, our practice-vs-AAC explainer draws the line, and the AAC basics hub holds the rest of the groundwork.
Frequently asked questions
What is the best completely free AAC app?
Cboard is the only widely available AAC app with no paid tier at all. It is free software under the GPL v3 license, runs in a browser and on Android, iOS, and Windows, supports 40 languages, and uses the Mulberry, ARASAAC, and Global Symbols sets. AbleNet's SoundingBoard is the strongest free pick if you want recorded-voice boards on an iPhone or iPad.
Is LetMeTalk still free and safe to use?
LetMeTalk remains free on the App Store with more than 9,000 ARASAAC images and full offline function. Its last update was August 20, 2018, and its US Google Play listing was unavailable when we checked on August 10, 2026, so treat it as unsupported software rather than a first choice.
Do free AAC apps work without internet?
It varies, which is why we checked each one. LetMeTalk states that no internet connection is necessary. SoundingBoard boards are recorded on the device. Cboard loads from local cache after first use but is web-first, so test it in airplane mode before depending on it.
How much do the big paid AAC apps cost?
Checked against the publishers on August 10, 2026: Proloquo2Go is USD $299.99 on iOS with no free trial listed, and TouchChat HD is $149.99 plus tax with a free Lite preview version. Expressive Go sits between, with a free six-screen tier and paid access at $9.99 per month, $49 per year, or $89 lifetime.
Will an AAC app stop my toddler from learning to talk?
No. ASHA reports that AAC use may help improve natural speech when used in a multimodal approach. Model the symbols while you speak, keep talking to your child normally, and treat the app as one more way in, not a replacement for speech.
When should we move from a free app to a funded device?
Move up when your child's vocabulary outgrows the free tier, when motor access needs exceed a consumer tablet, or when you cannot dedicate a tablet to communication. Schools must make assistive technology available when the IEP team documents the need, and insurance can fund dedicated devices as durable medical equipment after an SLP evaluation.
