Great for the field, but limited functionality

This app is great at what it does: it finds your location, downloads a checklist (if there is sufficient signal), and lets you tick off birds on the checklist. If cell service is lacking the offline checklist feature works great. However, you cant input age/sex or breeding code through the app, and once you submit a checklist you have to go through the (terribly mobile-unfriendly) eBird site to edit it.
