A Must Have!

This is a must have app for any birder! I also own the hard copy of this book. The digital version has some key enhancements that make this worth the money! My two favorites are the compare feature which lets you place birds side by side and the bird calls (which you can put on repeat!). These features are an amazing tool for new and experienced birders alike. Offering the "lite" preview version free is a sign that they know they are selling you a good quality product that they are proud of. Amazing!
