Good Study Tool
It is a good lights and switches tool in application version. Same as the books that with the desecription of every single switch at the aircraft. Will be better for the app to add the option of editing the descriptions and leave the new comment in another color or kind of letter so the student can customize its own study guide (as most pilots use to do with the paper study guide). Also will be good if the developers include the feature describing every item in the system pages of the ECAM such as name of valves, temperature limits, voltages, etc.
