ChirpOMatic Birdsong ID Europe

User from Germany here. This app does a beautiful job identifying bird song even with fairly quiet song or when there are multiple birds. Definitely excellent for birdwatching in Europe.

Don't know if it isn't narrowing by region or what the problem is, but I got a perfect capture of my bird song and it failed to identify the bird. After asking around and searching online, we ID'd the bird. The bird wasn't even in the list of possibilities listed in the app. For the record, it was a "Black-capped Chickadee". Avoid this app.

Designed to be used in UK? Purchased for use in US, a brief statement scrolled quickly past seemed to say it was developed for birds native to UK. That info wasn't available prior to purchase, can't find that reference again. Not clear what region it's useful in.
