Collins Bird Guide

Wish i had not upgraded!!

The illustrations and text is fine but the app is almost unusable because the navigation and search function is poorly designed. They seem to want you to find species by scrolling through families in groups by photo. Sometimes searching for a species by name works and sometimes it doesn't. A simple taxonomic list would be easier.

Waste of money. Not user friendly. Only drawing no real pictures. I wish I can have my money back.

No alphabetic lookup. A big waste of money. Grey letters in index difficult to read. Buy the book, not this app.

I really don’t like this app. Nothing ever comes up when I search on attributes.

I think the good reviews were seeded here when the app was first released. This is a pretty app, but the interface is sparse (as in it doesn't have many features) and the search engine is useless--you can choose a variety of criteria but it's not clear that what then appears is a subset or just an entire section (e.g. "Raptors") repeated without other criteria applied.
The descriptions are thorough and the drawings are nice. But there is no indication of names other than the English bird book one and the Latin name. No hope for those of us in non-English-speaking countries who want to use a bird book in English, but need to search based on what locals call a bird.
Look at the version history. I'd hoped, unreasonably, that it had been such a great app when it came out that it hadn't needed an update. Wrong. It needs attention and hasn't gotten it. Compare the version history to iBird Pro (North America) and you'll see what a living app's history should look like.
I really wish I could get my money back. Within 5 minutes of not being able to figure out how I'd use it productively (i.e. as a field guide, not to memorize birds), I knew I'd wasted my money.
And I still need a Swiss or Europe field guide app!
