Warblr is an app that automatically recognises birds by their song. The way in which it works is simple – make a recording with your iPhone, and Warblr will identify the species of bird/s that can be found in that recording, providing you with images and descriptions to help you learn more about our feathered friends.

In using Warblr, you will be contributing to a citizen science project, and hopefully one day helping to protect endangered species. We will be making the recordings and the data collected on species identification freely available to be used for research and conservation.

Warblr can recognise over 220 species of British bird, and works particularly well for garden and woodland species. Our technology uses the latest techniques in machine learning, and is supported by Queen Mary University of London.

Good app, but needs one important improvement

Simple to use and usually correct, however I wish the information on each bird also included a recording. Some do, but many don't. Otherwise I'm not sure which bird on the warble results is correct. It would be great if you could improve this.

Great outdoors app

I have had this app since it was introduced and have only just started using it regularly. It's easy to use and stores recordings so if there's no wifi they can be played back later.

A solid app

Great app. Really well designed, easy to use and accurate too! Update to allow you to listen back to your recordings is really useful! Really liking the social sharing too!
