It's good but it is missing some of the rooms that the audio guide has. For full information get the palace provided guide. Missing several items from battle room.
Extremely helpful when visiting the castle, this app allowed us to skip queueing: tickets at the hotel, no queueing for audio guide either thanks to get app. Make sure to start it and download before leaving for size reasons.

Very helpful application Describing every single point in the palace
Very useful audioguide Great audioguide with accurate maps.
This is a brand new app to enjoy the most of the Palace of Versailles.
