It gives a simple and long list of variations, not handy for navigation. Could be much better by means of a drop-down list. Some popular lines, such as the Sicilian Sveshnikov, need more details. Maybe, good for the absolute beginner level.

Seems like a great app, lists all the variations by Eco code so if you are trying to learn them or build an opening repotoire it's a handy and flexible resource.
