Field promise
Helpful, not overconfident.
Fish ID is there to help you decide, not pretend every photo is obvious. When several species look similar, GILLI shows the alternatives and lets you make the final call.
Great for checking unfamiliar catches on the water.
Useful when young fish, poor light, or wet hands make species harder to tell apart.
Keeps your logbook consistent with GILLI species names.
Designed as a quick helper inside the fishing flow, not a separate research tool.
