Hatch: Fly Fishing Companion

Hatch is the all-in-one fly fishing companion that helps you catch more trout. Identify insects with AI, match the perfect fly pattern, analyze your casting stroke in slow motion, and plan your trips with GPS-aware hatch charts — all backed by a beautiful fishing journal that tracks every catch, surfaces your stats, and connects you with a community of fellow anglers.

Built by anglers for anglers, Hatch replaces a tackle box full of gadgets with a single app. Whether you're nymphing a technical tailwater, swinging streamers for brown trout, or matching a hatch on a spring creek, Hatch gives you the intel to fish smarter.

AI INSECT & FLY PATTERN IDENTIFIER
Snap a photo of any bug on the water and Hatch's AI instantly tells you what it is — common name, scientific name, size, and the perfect fly pattern to match it. Got a mystery fly in your box? Take a picture and Hatch identifies the pattern and estimates the hook size. Never guess which fly to tie on again.

LOCATION-AWARE HATCH CHARTS
Know exactly what's emerging before you hit the river. Hatch uses your GPS location or any place you search to show seasonal insect activity — mayflies, caddisflies, stoneflies, midges, and terrestrials. Search any river or lake by name, see the active region, and get a real-time list of what's hatching right now. Check hatch timing by date, water type, and region. Perfect for trip planning: search "Madison River" or "Henry's Fork" and preview what bugs will be active when you arrive.

CAST ANALYZER
Record your casting stroke in slow motion and review it frame by frame. Hatch helps you spot flaws in your casting arc, timing, and loop formation with on-screen guides and pro tips. Tighten your loops, dial in your double haul, and reach rising fish you couldn't touch before.

STREAMFLOW
Real-Time CFS Tracking: Monitor current flow volume (CFS) and gauge heights for thousands of trout streams. Know Before You Go: Instantly see if a river is blown out, rising, falling, or dangerous to wade in.

FISHING JOURNAL & CATCH LOG
Log every trout with photos, GPS location, species, length, weight, and the exact fly that fooled them. Filter your catch history by river, species, or date. Track which fly patterns produce the most fish and build a permanent record of every great day on the water.

YOUR STATS
See your fishing story at a glance. Hatch automatically generates a species breakdown pie chart, your top-producing fly pattern, and your most productive water — all updated as you log catches. Know what works and double down on your most effective patterns.

ANGLER COMMUNITY
Share your best catches with a community of fly fishers. Post photos, like and comment on other anglers' catches, follow your favorite fishermen, and build your profile. Share directly from your journal or create a new post from scratch. Discover new waters, learn what's working for others, and connect with anglers who share your passion.

FLY BOX INVENTORY
Catalog every fly you own with photos, fly type (dry fly, nymph, streamer, wet fly, emerger, terrestrial), quantity, and hook sizes. Filter by category and link flies to journal entries to see which patterns are your most productive. Know exactly what's in your box before you leave the house.

ONBOARDING & TUTORIAL
