In the upper right part of the home screen, we see two icons, the first of them represented by a person's silhouette Image showing the accessibility button icon (see label 1 in the image above), which we will call the “Accessibility” button from now on, and the second icon represented by three horizontal lines  Image showing menu button icon (see label 2 in the image above), which we will call the “Menu” button.

The accessibility button is used to modify the font size with the options: small, medium and large. The font size is set to “Small” by default. In addition, thanks to this button we can also activate the high contrast mode, which makes the application convert the colors, to help reduce eye fatigue and make it easier to read or view the elements of the interface.

Below are some screenshots of these settings.

By clicking on one of the boards in the list, we will access that board. We observe that some of the cells have a blue mark in the upper right corner, this indicates that said cell is linked to another board. This means that when clicking on a cell that has this feature we will be redirected to that linked board.

Technical performance


The application in both the web version and for mobile devices did not present unexpected closing failures, but the following points were observed that can affect the reliability of the product:

  • In the Android version: in one of the tests, when the test user was authenticated and pressed one of the options in the “Frequently Asked Questions” menu (access from “Menu”  Image showing menu button icon), when going back with the device's navigation button, the user was redirected to the home page and wanted to access the "Menu" button again, but it was impossible, because when clicking on said button the application did not perform any action. Therefore, the test user had to close the application and open it again to access the menu options.
  • In the case of the application for mobile devices, an Internet connection is not necessary, unless you need to authenticate and have the features associated with your account.
  • Internet connection is required when using the web version.

How to consume it

During a period of one week, we have verified that the consumption of the battery and the consumption of data in the Internet connection is minimal.

Versatility and compatibility

SymboTalk is a free cross-platform application:

  • Access via a web browser (Chrome, Firefox, Opera, Microsoft Edge, and more) on a computer running Windows, Linux, macOS (requires macOS 11.0 or later and a Mac with the Apple M1 chip), and more .
  • Access via mobile app at smartphone o tablets with Android OS version 4.4 or later.
  • Access via mobile app on iPhone running iOS 12.0 or later and iPad running iPadOS 12.0 or later.


As characteristics to guarantee the confidentiality of the data, the authenticity of the identity and access to the application, we observe the following:

  • The user can create an account in the application, the authentication will be email and password. In addition, it is possible to authenticate with a Google account and it is not necessary to enter a password.
  • We have the option to delete our account and all our data from the server (Menu > Settings > Privacy settings > Delete account). In addition, we can delete our backups (Menu> Settings> Synchronization settings> Delete backup). However, when trying these options, the message “Deletion done” appeared, but the account was still active and we did not receive any email or something more reliable than a simple message displayed on the screen.

Remember that the delete account and delete backup options are only available if the user has previously authenticated.

  • The application offers access to the "Privacy Policy" and the "Terms and conditions of service", we recommend that you carefully read all the information contained in them.


This application helps different groups that, due to their physical or cognitive characteristics, have communication difficulties such as people with ASD, Down Syndrome, ALS, Aphasia, Apraxia, Stroke, Dementia, Alzheimer's, etc.

As we have mentioned before, SymboTalk is an augmentative and alternative communication system. People with severe speech or language difficulties rely on this type of communication for social interaction. If a person is able to speak to a certain degree (residual speech) we should encourage them to do so and complement their form of communication with this type of SAAC to help them communicate and thus improve their quality of life.

SymboTalk is a useful and easy-to-use tool that allows you to create and modify alternative communication boards in which completely personalized symbols (pictograms) can be added for users with different characteristics, abilities and needs.


We have certainly found this app to be useful and easy to use. It provides a simple and customizable interface to the user's needs.

While it is true, there are small bugs that need to be fixed, but none of them significantly affect the use of the application.

This tool is useful both for end users (people with communication difficulties), and for their families, caregivers, friends, among others, to facilitate or complement communication between them.


  • SymboTalk has different ways to solve doubts or problems that the user may have: contact via email, frequently asked questions section, YouTube channel and Facebook group.
  • Thanks to the accessibility button, it is possible to configure the font size and activate the high contrast.
  • To use SymboTalk you do not need to subscribe to the paid version.
  • We can create multiple profiles.
  • SymboTalk has more than 30 supported languages ​​for speech (Voice Synthesis) and it is possible to obtain more languages ​​by downloading an external application.
  • Default and user-customized dashboards can be downloaded in jpg and pdf format.
  • There is the option to record an audio associated with a symbol (pictogram).

Improvement points

  • The interface language is not available in all languages. Among the most prominent languages ​​for the interface we have: English and Spanish.
  • We found a problem in the Android version when entering Menu > Frequently Asked Questions, selecting any of the options in the list and pressing the device's "Back" navigation button, the menu button was blocked. We repeated this same test by pressing the close button (represented by an "X"), which appeared on the screen and everything worked correctly.
  • The communication of data to the user when deleting their account or backup can be improved.
