There are a few more articles on tying, flies and one quizz
Description ( from company’s site )
Collins Fishing Flies is the most complete guide to the huge range of flies now being used by fly-fishers around the world, whether fishing for the traditional quarry of trout and salmon, or for bonefish and permit on tropical flats, or for striped and sea bass from Atlantic beaches, or for toothy predators in Amazonian tributaries, of for pike in northern lakes.
Enables the fly-fisher and fly-tyer to select new flies for their local waters, or to select flies when heading off, to far-off rivers, lakes and seas.
Contains over 1300 photographed flies, together with tying and fishing notes and an extensive bibliography of fishing flies.
If you know the name of the fly, you will find it easily or you could find one by browsing around but it’s clearly the limitation of the most smart phone, a book is fairly easier to play with in this case.
I have found one error, perhaps it is the only one but it could be one of many. The salmon fly “Black bomber” is in fact a “Black bear yellow butt”. It’s not an error on the name as all bombers are floating and this one is wet.
Honestly, the app is well programmed but I can’t find a real usage for it.
