The nematode field sampling app enables the collection of nematodes from nature by offering an easy-to-use interface to record data on substrate, temperature, humidity, and other ecological parameters. The app gives investigators the ability to collect these isolation data in addition to GPS position and photographic evidence. Once nematodes are sampled from nature, this app has a companion application called "Nematode Isolation App" which can be used during the worm isolation process.
