An Chaothernach

Language Islands for Irish Learners

About

An Chaothernach is a mobile app for learning Irish through "language islands" - small collections of memorizable sentences about specific topics.

Based on Boris Shekhtman's method, the app helps you build fluency by creating pre-prepared speeches you can fall back on in conversation.
