Concise Irish Sign Language

The Concise Irish Sign Language Dictionary is an Irish Sign Language (ISL) video dictionary, currently containing approximately 1000 signs. Our aim is to provide a comprehensive ISL dictionary system in an easy-to-use form.

Concise ISL has been developed by two young, Irish engineers, one of whom is a life-long practitioner of Irish Sign Language.


Each word is portrayed in video form and accompanied by high quality images of the letters used in each hand to form the sign.

Signs are further sorted into categories, thus facilitating the learning process.

A simple, intuitive interface allows the user to search the dictionary according to both word and category simultaneously.

Through the addition of signs such as "texting", "tablet", "facebook" and many more, the dictionary reflects the modern context of the language.

The app is intended to be child-friendly, with the inclusion of a large number of signs in categories such as Animals, Colours, Food and Sports among many others.

Concise ISL makes use of features including swipe gestures and sliding menus.

The App currently includes approximately 1000 signs and we aim to increase this number periodically.

The App supports offline use. A data connection is required to download videos as desired. However, once downloaded videos can be viewed offline thereafter. A caching system allows the user to add and remove videos from your device as desired.

This allows the inclusion of such a large number of signs without imposing the consumption of an inordinate amount of on-device memory. The video size has been carefully calculated to reduce bandwidth consumption.

We hope you enjoy using Concise ISL!
