I downloaded the entire app and paid for all the sub categories (everything.) While you get a very wide range of what I presume to be all the fauna in Costa Rica, what you really get are just pictures. You get one picture of the animal, bird, reptile, or insect, it's Latin name and it's technical classification in the taxonomy of Animalia, and that's it. No description of the animal, no description of where you might find the animal, no description of its habitat, no description of its behavior, or no differential description between two similar animals. What do you get is a link to the Wikipedia page of each animal, bird, insect, etc. This works out great in all the Costa Rica jungles that have Internet access (not many.) This app reeks of laziness. It's essentially worthless.I intend to delete the app before I go to Costa Rica.

A fantastic resource for wildlife enthusiasts and professional workers alike. You’re paying for much more than just a field guide—the photography alone is artwork and the user interface is streamlined and sleek. You’re paying for an updatable photography book by a number of talented/skilled photographers. I think complaints about price miss this—the work done to achieve something like this is immense and there is no comparable resource like it for Costa Rica. Physical field guides suffer from the fact that taxonomy is ever-changing and fluid. A guide such as this can be updated to add taxa and bring things up-to-date. This is the future of field guides.

Súper buena app, buen contenido y muy diverso, as a local Naturalist tour guide of Costa Rica is super helpful, easy to used, maybe in the future can put more info, but for start is good! También más información en español, detalles y demás!!! Pero para ser una guía de bolsillo está muy buena y práctica, la info se corrobora en el campo con otras guías, libros y más!:) Muchas gracias, thanks a lot for try to show more of my beautiful country to the world!!!! Buenas vibras y PURA V1DA!:)

Free version is useless. Looks like it depends on WiFi for information so I’m not paying for full version. WiFi is very rare and slow in Costa Rica.

The information is not good unless you pay. And the free version is not compelling enough to make me want to pay (and possibly be disappointed).

Downloaded app on an iPhone 7 with 12.1.4 iOS. Opened the app and it just displayed the main screen. Tapping screen does nothing.

It has pictures but very little information. Any field guide that depends on Wi-Fi especially in Costa Rica is worthless! If you want information you have to connect to Wikipedia.

I had trouble (mostly my fault, not being a tech-weenie) getting everything loaded, and the app creator (in Austria!) was super-helpful, spending more than 2 hours on chat with me! The app will be a great resource on my upcoming (fifth) visit to Costa Rica. It could use more detail and is missing a few species I know should be included, but it also has a huge species list, very useful for those biota for which I don't carry a field guide, since I'm mainly a birder.

Although it indicates it woks on my iPhone 6+, once it loads it freezes and then closes. No idea what it’s like as I can’t get past the front page.
