THE HATCH CHART APP
Know the water.
Match the hatch.
Live hatch charts, fly patterns with full tying recipes, river conditions, and push alerts when the bugs come off — all powered by your local fly fishing organization.
Free to download — connect with your organization’s code, or try DEMO.
Everything a fly angler needs, in six tabs
🪰 Hatches
Every insect on your water with an Active Now badge, month filter, lifecycle stages, hook sizes, and field tactics from local experts.
📅 Timeline
A full-year chart of every hatch across all 12 months — surface and subsurface activity shown separately, so you can plan trips weeks ahead.
🧰 Fly Box
Save any pattern — with its full tying recipe and hook size — to your personal Fly Box. Stored on your device, available offline at the vise or on the water.
🌊 Rivers
Live USGS gauge data — flow, gage height, water temp, turbidity — with wading-safety ratings and one-tap directions to public access points.
📣 Reports
Real-time hatch reports from anglers on your water — what’s hatching, how heavy, water temp and clarity. Share your own in seconds.
🔔 Smart Alerts
Push notifications when conditions line up — water temperature, season, time of day, cloud cover, even turbidity. Know before the hatch starts.
