Field notes
The described workflow combines live camera highlighting with adjustable sensitivity, haptic alerts, and tap-to-pin GPS markers that can include a photo and note. The site says users can pause a trail and resume later, and export tracks as GPX. It also cautions that the color-based detection can highlight red leaves or clay, so the visual cue is not presented as definitive identification.
