Will it tell me the best time to fish?

No, and that's deliberate. It won't predict catch rates either. It reports conditions and how well it knows them; the judgement stays yours. An app that promised otherwise would have to invent the parts it can't measure, which is exactly the habit this one is built to avoid.

What does “unknown” actually mean?

That nobody has entered a season for that water, or the gauge feeding it has gone quiet. It stays unknown rather than becoming open, because the difference between those two words is a citation — and being wrong about it can cost you a ticket.

Where does the data come from?

USGS stream gauges, the National Weather Service, Caltrans and Nevada 511 for road status, satellites reading lake surface temperature from orbit, and the Owens Valley's own flow pages. Roughly a dozen sources, each with its own reliability, which is what the confidence number is made of.

Which waters are covered?

The corridor — Reno down through the Eastern Sierra to the Owens Valley: the Owens, Bishop Creek, Crowley, the Mammoth basin, the June Lake Loop, Bridgeport, the Walkers and Topaz. Coverage widens as more measurement becomes available for each water.

When can I actually download it?

The public beta is aimed at the 2027 general trout opener — the last Saturday in April. Founding members get TestFlight builds over the winter before that.

What is it going to cost?

Final pricing isn't set yet, and we'd rather say that than invent a number. One thing is already committed: founding members never pay more than the founding rate.

Is there an Android version?

iPhone first, and done properly, before anything else. If enough Android anglers put their name down, it moves up the list — so put your name down.

What happens to my email address?

You'll get an email when the beta opens and one when we launch. Nothing else, no lists sold, unsubscribe any time. Questions go to hello@angler395.com.

What is Angler 395?

Angler 395 is an iPhone app, now in development, for anglers who fish the US-395 corridor from Reno down to Lone Pine. It combines live stream flows, water temperatures, weather and road conditions from roughly a dozen sources into one fishability score per water, and shows how much real measurement sits behind each score.

What it does

Calibrated, not confident

Most fishing apps are a weather widget with a fish on it — a number with no account of how it was reached. Angler 395 reports conditions and how well it knows them, because on this road the second part is what makes the first part worth trusting.

One answer, not a dashboard

Every water gets a fishability score built from live flow, water temperature, weather and access. At 5am you want a number and a reason, not twelve tabs of raw gauge data.

Every score shows its work

Each score arrives with how much real measurement is behind it. A river running 6 cfs on a gauge reporting nothing else says exactly that, instead of hiding it behind a confident-looking number.

Unknown stays unknown

A lake nobody has entered a season for reads unknown — never open. The difference between those two words is a citation, so we don't paper over the gap with a plausible guess.

The road is part of the forecast

Caltrans and Nevada 511, folded into the same answer. Perfect flows above a closed Sonora Pass aren't a fishing report, they're a four-hour detour you find out about at the gate.

Sources a national app won't touch

USGS gauges and the National Weather Service, plus satellites reading lake surfaces from orbit and the Owens Valley flow pages that still publish their numbers printed on a picture.

Dates that move

The general opener is the last Saturday in April; other waters shift year to year. You'll know a season is still nine days out before you load the truck, not when you get there.

Where the numbers come from

The main source types behind each fishability score — roughly a dozen sources in all, each weighted by how reliable it is.
Source	What it measures	Score input
USGS stream gauges	Live stream flow on rivers and creeks	Flow
National Weather Service	Weather conditions and forecasts	Weather
Caltrans	Road status and closures in California, including Sierra passes	Access
Nevada 511	Road status and closures in Nevada	Access
Satellites	Lake surface temperature, read from orbit	Water temperature
Owens Valley flow pages	Owens River flows, some published as numbers on an image	Flow

What it deliberately won't do: predict catch rates, or tell you the best time to fish. It reports conditions and how well it knows them. The judgement stays yours.

Founding members

395 people get in before the first cast

This isn't a mailing list. Founding members shape what ships — which waters get measured first, which numbers land on the home screen, and where the confidence model is still lying to us. In exchange, you get the app early and you never pay more than you did on day one.

Founding rate, locked for life
Whatever Angler 395 costs later, you keep the founding price for as long as you use it.
TestFlight before anyone else
You'll be fishing with early builds while the public beta is still a screenshot.
A direct line to the builder
A private channel, not a support queue. Founding feedback goes to the top of the list.
Your home water gets measured first
Tell us where you fish and that stretch moves up the queue for sources and calibration.
Founding badge in the app
A small thing. But you were here before the first cast.

Roadmap

Where this is, honestly

No pre-orders for vapor. Here's what's built, what's next, and when you'd get your hands on it.

Now · Fall 2026
Wiring the sources
USGS gauges, the National Weather Service, Caltrans, Nevada 511, satellite lake-surface reads, and the Owens Valley pages that publish flows as numbers on a picture — plus the model that decides how much any of it is worth.
Winter 2026–27
Founding TestFlight
First scores on real water, each one carrying its confidence. Rough edges included, on purpose: the point of this stage is finding where the data lies to us.
Opening day 2027
Public beta on the App Store
Timed to the general trout opener, the last Saturday in April. Founding feedback decides what makes that build.
After the opener
More water, tighter confidence
Widening coverage down the corridor and narrowing the error bars on what's already there — more measurement behind more scores, and fewer waters reading unknown.
