Angl — Know before you go. Live river conditions for fly fishing.

One glance. One answer.

Every river, honestly ranked

Angl reads the same data the guides read — flow vs. its seasonal band, water temp, clarity, trend and safety — then commits to a call. No dashboards to interpret.

GO · 0.84

It's fishing.

Flow sits in its productive band, water's cool, clarity's clean and the trend is steady. Grab the rod.

MARGINAL · 0.48

Fishable, with a plan.

A little high, off-color or warming. Angl tells you why so you can pick the right water and hours.

BLOWN · 0.21

Save the drive.

Runoff, a spike or a thermal risk. See it from the couch instead of the boat ramp.

How it works

From "maybe" to on the water

Three taps between opening the app and knowing exactly where — and when — to fish.

1

Pick your water

Browse by state or tap "Near Me." Every river is color-coded before you even open it.

2

Read the verdict

Live flow, temp, clarity and gage height — with a one-line reason for the call and the typical band.

3

Time it right

Solunar windows, first/last light and a 7-day flow forecast tell you the hour to be standing in the river.

What's inside

The whole river, in your pocket

Everything the pro apps charge for — flows, maps, forecasts, safety — fused from free public data.

Flow trends & gage height

A 45-day sparkline over each river's own typical band, live gage height in feet, plus a 10-year historical range so today's number actually means something. Toggle cfs or feet, and drop a personal reference line — your wading limit, your favorite level.

Solunar best times

Major & minor feeding windows, dawn and dusk light — the hours that actually fish.

Layered maps

Satellite, daily true-color imagery and live NEXRAD radar, with public access, boat ramps and fly shops pinned.

Condition alerts

Set a flow, level, temp or clarity threshold and Angl flags the moment your river hits it.

Safety & regs

Flood-stage banners, thermal-stress warnings for the trout, and a link to the state's official rules.

Flow forecasts

NWS river forecasts show where the flow is heading over the next 7 days — plan the weekend early.

Gradient profiles

Every river's drop in ft/mile and elevation range — read the character of the water before you scout it.

Plan a float, log the day

Pick put-in and take-out from mapped access sites, then log your outing — Angl saves the conditions so next time it can tell you "your fish come at ~1,500 cfs."

A spot, end to end

One screen. The whole story.

Open any spot and everything you'd stitch together from five websites is already there — scrolling by, live.

1

The call, and the why

"GO · 0.74 — runoff past, snowpack gone, settled summer flow."

2

Conditions vs. normal

Flow, water temp and wind, each drawn against the band that fishes well here.

3

Where it's heading

NWS forecast, 10-year historical range and the solunar windows for today.

4

Make it yours

Favorite it, set a GO alert, log the day, or file a guide report for the community.

Questions, answered

Is Angl free?

Yes — reading flagship rivers, their verdicts, conditions, maps and best-times is free forever. Angl Pro unlocks every water plus alerts and planning tools. Beta testers get everything unlocked.

Where does the data come from?

100% public sources: USGS (flow, temp, gage height), NOAA/NWS (weather & pressure), NWPS (river forecasts & flood stage), USDM (drought), NRCS SNOTEL (snowpack) and USGS 3DEP (elevation). No paywalled feeds — Angl just reads them for you and turns them into a verdict.

Which rivers does it cover?

The western US to start — Montana, Idaho, Colorado, Wyoming and expanding — with 229 spots scored today and more added regularly. Any river with a public USGS gauge is fair game.

How accurate are the verdicts?

Verdicts are built from live gauge and weather data updated continuously, weighed against each river's own seasonal band. It's decision support, not a guarantee — always confirm local regulations, closures and safety before you fish.

Is there an Android version?

iOS comes first — the TestFlight beta is live now. Android is on the roadmap.

When will it be on the App Store?

Angl is in TestFlight beta today. A public App Store release lands with launch — join the beta to get it first and help shape it.

The river's telling you something.
