The solution.

With Zumoone d.o.o. we prepared a fresh redesign of the mobile app and improved the user experience in terms of intuitiveness, functioning speed and interactivity. The mobile app offers a unique way of learning international signs and communicating with deaf people of different nationalities.

The mobile app International Signs offers many collections with videos, which present single signs to contact with the deaf in the world more quickly. The first collection is free-of-charge and available to all users, further collections are accessible upon an in-app purchase. Users can learn over 1000 signs. This app was developed to overcome communication barriers among deaf members of different nationalities as well as a desire for simple communication.
