Pricing, motor planning features, and device compatibility vary per model (like android tablets vs iPads). Many families prefer LetMeTalk because of its many customization options, whilst others prefer TD-Snap because they want to include members of their care team in the language learning process. It might be difficult to figure out which app is the greatest fit for communication. Continue reading to find out how both applications compare in terms of vocabulary levels, parent onboarding, customer service, and more.
LetMeTalk |
TD Snap |
|
|---|---|---|
| Good for Early Communication |
Not ideal for users who have no foundation of language.
|
TD Snap limits early learners because it does not have a robust enough vocabulary to give early learners a place to grow.
|
| Affordable Pricing |
The app is free. However, there is no support included and the quality of the application is low and is not recommended by speech therapists.
|
The dedicated devices offered are thousands of dollars, and the iOS or Windows app-only version is $49.99.
|
| Easy to Get Started |
All the video tutorials on the associated website are in Spanish, and little support is offered.
|
There is little support in setting TD Snap up, leaving caregivers to spend quite a bit of time figuring out how to customize it on their own.
|
| Behavior Supports |
No features that develop behavioral skills are offered.
|
TD Snap does include some schedules, timers and scripts to help kids with transitions, but they are not of the highest quality.
|
| Multiple Devices |
Available on iOS and amazon, but is no longer available on the Google Play store for android devices.
|
While TD Snap does have a dedicated device option that is expensive, the app-only version is only available on iPad.
|
| Easy Parent Modeling |
Very little power is given to parents to interact with their child's new language. They would need to download the app on their own phone and point everything out, or take the device away from the user.
|
This app includes an internal search bar to show the path to words, but it requires taking the device out of a child's hands.
|
| Incentives to Practice |
No incentives to practice LetMeTalk, and many users get frustrated with the interface and no longer look forward to practicing.
|
TD Snap does not have a point system or incentive program to help kids learn faster.
|
| Natural Voices and Language Availability |
16 languages are available, but there are very few voices to choose from. There also seems to be a consistent glitch where the sound does not play when tapping words.
|
TD Snap is available in Chinese, Czech, Danish, Dutch, English (US, CA, GB, AU), Finnish, French, German, Icelandic, Italian, Japanese, Norwegian, Portuguese, Spanish, and Swedish. Multiple voices are offered, with the option to purchase additional voice engines.
|
| Customer Support |
Very little support offered in English or in real-time. When clicking "support" in the app, users are taken to an "error" page.
|
TD Snap is made by Tobii Dynavox, so to get support outside of FAQ articles, you need to reach out to them via phone or email during office hours.
|
| Motor Planning |
No clear organization or strategy to helping users learn language consistently.
|
TD Snap uses Core-First Vocabulary. It also has expandable grid sizes, which can make learning through motor planning difficult.
|
| Simplicity of the Screen |
The image-to-text size ratio is confusing to users and makes it difficult to read.
|
There is a strange scrolling sequence that can be confusing!
|
| Reminders to Practice |
No reminders to practice AAC included with your purchase.
|
TD Snap has a very limited functionality that includes language, but not reminders to practice new skills.
|
| Image and Symbol Quality |
LetMeTalk uses 9000 pictograms of ARASAAC.
|
While there is a limited symbol set included, users can add their own symbols. However, it does offer a lot of diversity options when editing symbols.
|
| Fun Games to Build Skills |
There are no games in LetMeTalk that help AAC users improve their finger dexterity.
|
Unfortunately, there are no games included with the purchase of TD Snap.
|
| Affordable Dedicated a Device Option |
LetMeTalk is only offered as an app to be downloaded on a device already owned.
|
Because TD Snap is offered through Tobii Dynavox, all the dedicated devices can be thousands of dollars and are expected to get medicaid or insurance involved.
|
| Communication with Spelling |
There is an alphabet included but no spelling words included.
|
TD Snap does include a page for literate users to spell words.
|
| Choose from Levels of Vocabulary |
LetMeTalk's vocabulary responds to PECS or a more traditional AAC (Augmentative and Alternative Communication).
|
The only words available are those in the Core First vocabulary.
