This app is designed to help you perfectly execute the moves you selected for your openings. It uses advanced memorizing techniques (such as spaced repetition) which focus on your weaknesses.
What it means is that this app is able to identify the positions for which you have problems and help you to correct these weaknesses.

With this app you only need to learn ONE move per position and be prepared for ALL possible responses from your opponent. Please note that many apps already exist to explore the different chess openings variants but this is not the purpose of this app. What make this app unique is that it will rather help you to execute a plan that you carefully prepared in advance. This will give you a serious advantage against any opponent.
