Duck Movement (50%) covers weather severity, wind push, and season timing — including blue-winged teal's own early-September window — plus a real barometric-pressure signal, with Freeze Severity, Temperature Trend, and Pressure Trend broken out right below it so you can see exactly what's driving it. Water Conditions (30%) and Huntable Wind (20%) round it out. Three numbers, three weights, always visible — no toggle to dig through. During the off-season, the score is automatically held low so a warm, quiet weather day never gets presented as active migration.

QuackIndex pulls the closest qualifying USGS and NOAA gauges within 25 miles of your spot and translates the raw numbers into what they actually mean for a hunt — is the water coming up (often a good sign, flooding fresh feeding ground) or dropping fast (birds pushing off to bigger water)? Every reading shows its exact distance from your spot and its trend over the last several days, not just a single snapshot. For coastal and marsh spots, QuackIndex also detects tidal water automatically and factors in the nearest NOAA tide station's rising and falling movement, since that matters as much as river stage for a tidal hunt.

Zoom deep into your exact spot with high-resolution imagery, hillshade-tinted terrain, or a classic topo view, then layer on contours, water, wetlands, and public-land boundaries pulled from USGS 3DEP, National Hydrography, and PAD-US data — so you can scout access, cover, and property lines before you ever leave the truck.

Every hunt log captures a snapshot of that day's QuackIndex conditions alongside your own notes and harvest count, so months later you can see exactly what was happening the day birds worked. A companion scout journal tracks what you find while checking a spot before you ever hunt it. Once you have logged enough hunts, AI Insights looks across your own history for the patterns that actually apply to your spots — not generic advice.
