Good content, suboptimal execution
Lots of good information as it is based on an authoritative original source. Translating that content into a truly useful app, however, is somewhat of a mixed bag. Some aspects that I find frustrating include: -descriptions and illustrations are not both visible at once in the same page view so I’m constantly swiping back and forth to match features with their description; -portrait only view (fine for phone but can’t use it easily with my iPad’s external keyboard); -the life list feature seems pretty useless because there doesn’t appear to be any way to see only the species you’ve included on your life list and scrolling through 1661 species to find the ones you’ve checked off is a non-starter. (This isn’t a huge deal since I keep my life list in eBird anyways but I had hoped to use the feature to create a small group of birds to study at a time by comparison.) Good features include filtering by location (region) to show most likely species and multistep help with identifying unknown birds (similar to Merlin app). One feature that I would love to see added would be a quiz mode where you could select the species or group of species that you wanted to review and you could take a test to identify species by illustration or sound. Overall, still a useful app but it could be really great with some improvements. Leaves me a little disappointed considering the price.
