“This electronic field guide covers all the rattlesnakes of California. The high quality photos document the variability of each rattlesnake species and subspecies. This app field guide is useful to the general public, providing quick information to distinguish a rattlesnake from the many harmless snakes of the state, and also provides great detail useful to those more familiar with rattlesnakes. This guide also provides field first aid information in case of a bite. All this content is available without Internet connectivity, but links to other useful websites are available with an Internet connection. At 99 cents, this field guide app is a great value compared to printed field guides and very portable.

As the title suggests, the guide is limited to the California rattlesnakes.”
