## Gnatcast Description
Gnatcast — The Biting Gnat Index

Know exactly when the no-see-ums are going to swarm.

Gnatcast is the first hyper-local forecast tool designed specifically for biting midges (no-see-ums). While regular weather apps ignore the real reasons gnats explode — low tide, calm wind, high humidity, and marsh exposure — Gnatcast combines real-time WeatherKit data, NOAA tide predictions, and live community reports to give you an accurate 0–100 Biting Gnat Index.

Perfect for coastal living in the Southeast and Gulf Coast — from Beaufort to Charleston, Savannah, Hilton Head, Tampa, and beyond.

Key Features:
• Live Biting Gnat Index (0–100) with color-coded risk level
• 72-hour hourly timeline showing exactly when swarms will peak
• 10-day daily forecast with min/max risk ranges
• Real NOAA tide integration — risk spikes hard at low tide
• Live BiteRep heatmap — see where others are currently getting swarmed
• Submit your own BiteReps to help the community
• Micro-climate adjustments for wind shielding and shade in your backyard
• Historical seasonality chart so you know what “normal” looks like

Whether you're planning a round of golf, a day at the marina, a beach walk, or just want to sit on your porch without getting eaten alive — Gnatcast tells you when it’s safe and when you need the Thermacell or DEET.

Built for the Low Country and Coastal South. Backed by real science, real tides, and real user reports.

Download now and finally stay one step ahead of the gnats.
