In reply to ewanjp:
I'm assuming you mean the Jura that are in France/Switzerland/Germany? If you mean Poland then I can't help, sorry.
If France/Switzerland/Germany then Plaisir Jura is the book you want: https://www.filidor.ch/Pages/Book.aspx?Id=82
If you buy the book you get a code to download all the data to your tablet/phone.
You can also get some info on the spread of grades/crags etc at: https://www.vertical-life.info/en/areas/56-jura-switzerland (just click on the different areas for more details).
If you don't want to shell out nearly 40 quid for the book then you can get all the data in the book via the Vertical Life app. I'm assuming the credits are the same on Android/iPhone etc but it's 50 credits for the whole book (works out about £15 or thereabouts as 60 credits = £16.99 ) or you can buy individual crags etc.
