The documents behind the questions
Every question in the app cites one of these, and every explanation names the clause. Here is where to read them for yourself.

These documents are revised from time to time, and a revision can change an answer. The app's questions are written against the editions current when they were authored, and the explanation always names the clause so you can check it against whatever edition you are working to. If you spot a question that a newer edition has overtaken, tell us — that is the most useful message we get.
Everything here covers England. Reinstatement specifications and some duties differ in Scotland, Wales and Northern Ireland.
