A promising start - but we want more! – Scott Catalogue Review

This is based on the free download and looking at the screen shots, which seem to be a PDF version of the printed book. The interface is clear and simple to navigate, but to really make this a killer app, it's going to need to add some more interactive features. My suggestion list: The ability to check off or annotate the stamps I own; add a photo of a stamp I own to its listing; cross-reference "confusible" stamps with a tap on the screen (instead of reading a footnote and browsing to that listing manually); link to articles about notable stamps in Scott Stamp Monthly (now part of Linn's Stamp News); tap to see a database of recent auction results for famous rarities. And if they really want to get fancy (and useful): the ability to take a picture of any mystery stamp and have the app identify it and take you right to the listing. I felt the requirement to buy the catalog in $30 "chunks" rather onerous - I've never spent more than $14 on an app for iPhone or iPad. The book version of the worldwide classic catalog retails for $129, and the three pieces of it in this app add up to $90. Not much of a discount, considering how little functionality has been added so far. There isn't even a way to test-drive, say, one or two countries for free. I think I would rather be able to pay 99 cents per country, even if that adds up to more money overall, than have to plunk down all that cash for a third of a catalog I might not like. Also, will there be a discount for upgrades to future editions?
