A stunning visual guide to identifying trees of the British Isles.

Great fun to use, identification can be enjoyed by the whole family.

The original and the best, TreeId is an easy to use but comprehensive field guide to trees found growing in open countryside and natural woodland of the British Isles. The guide has been created by professional published ecologists, accept no cheap imitations!

One of BBC Countryfile's top 10 apps and one of the World Wildlife Fund's top 10 apps. Described as "incredibly useful" by ITV's Seth Conway and "a lovely app" by Adam Vaughan of the Guardian. It was voted No. 5 in the Guardian Green Living top 10 apps and was given the "Best" award by iPhone Apps Plus. Our app is the only tree identification app in the Woodland Trust top apps list.

Have you ever been on a walk in the countryside and wondered "What tree is that?"? TreeId is a great tool to help you quickly and easily identify trees you find in the British countryside. It's great fun to use, too. With TreeId, identification can be enjoyed by the whole family, and can engage children with the natural world around them. For the tree enthusiast, there is comprehensive anatomical and ecological information, with high quality images of the leaf, flower, fruit etc. of every species.

When you have identified a tree, why not take a photo and record it on our map. See how many species you can identify this year!

The app does not need an internet connection, all content is downloaded when the app is purchased.

Tree ID


I love this ap - we've recently moved to the wilds of Norfolk from the wilds of Essex (yup! A superhuman effort to travel so far!).

Seriously though, since arriving here I've found myself being more interest in the trees surrounding us. Equally, having the Bird ID App (from the same studio I believe), I find myself taking a greater interest in the birds in the area.... Having these two apps I seemed to want to know what that tree or bird I've discovered on my travels - can't get this sort of encouragement (in such a passive way) from many other Apps.

No, I'm not going start wearing tweed nor a deer-stalker upon my head 😄😄😎

Great in your pocket identifier


Always wanted to be able to identify accurately the beautiful trees that I come across. This hits the nail on the head. Easy train use, gives you percentage hit rate based on the questions you answer. The. You can look at pictures to compare. You can even mark the trees you have found on the map. Definitely a must have. Works on iPad well but great to have on the iPhone so that you always have it.

Good app


This is a quality app and has taught me a great deal about the trees I see everyday whilst out and about. It obviously focusses on trees native to the British Isles which is fine but you will soon find that many trees planted around parks and towns are immigrants, imported for interest from far flung shores! If the app was expanded to include a few of the more common of these trees, (i know it couldn't have every tree ever!) then it would merit the full five stars!
