3.0 out of 5 stars Mixed bag January 23, 2012

I love the concept of having these field guides on my Kindle Fire and hiking with them, and ideally would like to purchase them all for my Kindle Fire. The photos are wonderful and the information presented is helpful. I have this field guide in book form too, but this has even more in it than the book, so I do like it. But as another reviewer has pointed out, it is buggy. Whether locked or unlocked, the program turns itself over 180 degrees between pages, so you are constantly flipping it over. Very annoying. Several pictures are offered for each tree, but often there will be a space where a photo is credited but there is only blank space. I have also purchased the Field Guide for Mammals app, and both of these programs have a feature where you can register and keep track of the species that you have seen. Neither program will let me register and I've made many attempts, only to get a 'bad log in' response. Time consuming and annoying. I'd like to see these problems fixed before I purchase any more of these Field Guides.

After receiving Audubon Birds as the Free App of the Day, I was impressed enough by it to purchase several of the other Audubon Field Guide apps.

Like the Birds guide, there is so much information in the app it can be overwhelming if you try to browse through it like a printed guide book. Fortunately, there is a very handy search function that allows you to find a tree based on its attributes such as shape, region, flower color, leaf shape, fruit and bark.

The app lets you keep a life list, record sightings and take photos, and then upload them to

Because of the huge volume of data available, this app does require a data connection or a 400 MB optional download. If you choose not to download the data, it could chew up considerable bandwidth if you have a limited data plan.

This app does not include many common cultivated fruit trees such orange, lemon, apple or date palm. (I had the first 3 of these in my backyard in California, and date palms are common in Southern California.)

This app could use more photos of seeds, acorns and pods.

The app force closed on my HTC Evo 3D while I was trying to search for a tree.

The app works well enough on my tablet, but it can't make up its mind whether it wants to run in landscape or portrait.

3.0 out of 5 stars Good Start, Looking Forward to Improvements March 11, 2012

Let me just say I love the hardcopies of the Audubon guides. They are concise and well suited to being outdoors whether you are hiking, camping, birdwatching, hunting or just out on a walk. I was delighted to see them moving into the mobile app field and decided to give Trees a chance since it was priced at $4.99 instead of the $9.99 of some of the other apps.

- Offline content. Although this is substantial download (performed after installation and best done by wifi), this allows you access to the full contents of the guide while potentially far from a mobile connects
- Lots of content. While I have not done a page by page comparison to their counterparts, the Trees guide seems pretty comprehensive.
- The sightings, personal content, sync and camera features are very nice to have!

- Images are bit lower in resolutions than I'd prefer. The range maps, in particularly are quite grainy.
- The interface could be a bit slicker, although there is a decent search and match function, the app feels more like a webpage converted to an app than a dedicated resource on my phone & tablet
- Initial loading of the app is very slow.

Overall, I'd recommend the Trees apps for those that travel with their devices. I do think that the $9.99 price point is too high though, and these should be $4.99 across the board (like the Trees app).

1.0 out of 5 stars It needs to be simpler March 4, 2013
Verified Purchase
After trying for more than 30 minutes to look up a simple cherry tree in my front yard I finally gave up in frustration. I never did get this app to admit that cherry trees even exist. The search function and the advanced search seem to be utterly worthless, and for the life of me I can't figure out any logical pattern to how these functions decide what entries to show, and what ones to not show, based on your input. For example, let's take the aforementioned cherry tree. If you go to advanced search and enter "cherry" for the name (scientific, alternate or common) and let it search, you get exactly two results: Hollyleaf Cherry and Sweet Birch. That's it. As far as the app is concerned, those are the only entries in the database to which the word "cherry" applies as a name. And one isn't even a cherry tree. If you were then to play with the search some more you might find the Cornelian-cherry (though it will not come up in a search for just "cherry") and look at its entry. You might even be tempted to click and see what the range is where it can be commonly found... whereupon I keep getting a message saying that the range maps aren't available, sorry for the inconvenience.

This app simply is not worth the $4.99 asking price. In fact, I don't think it would be worth $0.99.

3.0 out of 5 stars Great Idea, Faulty Execution January 23, 2013

This app has a lot of potential. There are several pictures for most species and several ways to search. The app can be slow and if you choose to download all data to your device the download takes a long time and sometimes freezes.
