TaxonDroid

Overview
TaxonDroid is a handheld taxonomical guide for identification of freshwater invertebrates running on Android OS. The application is based on the book entitled Freshwater Invertebrates in Central Europe by György Kriska, Eötvös Loránd University, Budapest and developed by Pál Barta, Estrato Ltd, Budapest. 

The hierarchical (tree) structure of its database allows for quick and easy identification of the observed taxon in the field by answering a few questions relating morphology (phenotype). The step-by-step approaching path from general attributes as far as the target species is reached can be traced back and is modifiable at any point.

Features

● Over 50 freshwater macro-invertebrate animal taxa can be identified
● Over 200 full colour digital images and drawings can be viewed
● Where applicable, short video recordings illustrate the behaviour of animals
● Target taxa are reachable in 2–11 identification steps
● Short descriptions are available at each step to allow for further branching
● The selection path history is retraceable and at any point can be started a new path
● Compatible with Android from version 2.1
