The app uses Augmentative and Alternative Communication (AAC) in a synchronised way.

It makes it possible for everyone to communicate effectively and accurately on a daily basis. Thanks to the app the user is able to communicate their needs and perform not only simple chores, such as doing shopping, but also more complex tasks, such as making appointments at government offices. Nearly 100 categories and subcategories covering daily life situations are arranged into simple, easily readable buttons. They are presented with icons, thanks to which people with varying disability levels can easily choose the activity or message they need.

After pressing a button, the selected message will be played from the speaker of the user`s telephone or other mobile device. After the interlocutor replies, the user can respond by entering the answer via the function “Say something”, or they can choose the simple “yes/no” answer, or use another button.

HearUs enables unrestricted communication between a mute person and a carer, a doctor, a bus driver or any other person they meet. In addition to everyday life situations, such as expressing the need to use the bathroom, the app contains all important functions, such as reading out the list of received medications and informing a relative or a friend of an emergency.
