Thanks to a friend who said he had downloaded it, I took a look: the link was a long way down the page on Facebook, but has since been pinned at top of page for easier access (at my suggestion!)
It re-directs you to the Whitby FW website but, and again I mentioned this, only refers to Android and Apple PHONES. I took a punt on trying the Apple link to download it to my iPad and it worked - eventually, after updating my credit card expiry date! Cost me £3.99.
Now wondering if, being an old-fashioned soul, I shall still need/want a paper copy I can pepper with highlighter pen, but they tell me you can "star" any items of particular interest to you.....and maybe, still to come...if you have a particular instrument interest, there will be a way of segregating that, Whoooo!
