I have been using this app on my Ipod Touch for a couple of years and find it very useful. I like to add trip birds as I go along, and previous versions showed my trip list in taxanomic order, but I could only export in the order I entered the sightings, which was a problem for my reporting what I had seen. The new version (1.9) has a new interface that I like better, but the trip list is now shown only in alphabetical order which makes it difficult to review the list to check if I have entered all of the birds seen on the trip. I see that a version 1.9.1 is out, but my Ipod Touch doent see it as an update.
