TightLines — pay-what-you-want fishing forecast app for Washington State

What is TightLines?

TightLines is a friendlier take on the state fishing app. Choose the species you are after and the bite model re-tunes itself, blending solunar feeding windows, dawn and dusk light, barometric trend, wind and water temperature into a single 0 to 100 bite score. A 7-day outlook shows which day and which hours to go.

🐟

Species-aware model

The score changes with the species you pick, because a trout and a bass do not bite on the same cues.

🌙

Solunar windows

Major and minor feeding periods are worked into the score.

🌅

Dawn and dusk light

Low-light periods are weighted for the fish that favor them.

🌡️

Weather and water

Barometric trend, wind and water temperature feed the model.

📈

7-day outlook

Plan the week and pick the best day at a glance.

How it works

Open the app. Use the launch button on this page. Nothing to install.

Read the score. Check today and the 7-day outlook, then pick your window.

Pay what you want 🎟️

TightLines has no trial, no license key and no nag screens. Open it and use it. If it earns a spot on your phone, chip in whatever you think it's worth. $9.99 is the suggestion and the range most people pick is $3 to $20, but you set the price.

$9.99 — the sweet spot 🎣

The suggested amount, for a season on the water. Thank you!

Pay $9.99 with Venmo

Tap the button and Venmo opens with your amount and “TightLines” already filled in (you can still change it). Or scan the code with your phone camera and pay @FredrikHWinsnes. Paying nothing is fine too.

Questions

Is it really free?

Yes. There is no trial and no locked feature. $9.99 is the suggested contribution, but any amount, including nothing, is welcome.

Is the bite score a guarantee?

No. It is a model built on conditions that influence fish behavior. It improves your odds and does not replace local knowledge.

Does it cover states other than Washington?

The spots and rules are for Washington State. The forecast model itself can be applied anywhere.

Are the regulations official?

No. Always check the official Washington Department of Fish and Wildlife rules before you fish.

Do I get anything extra if I pay?

No. You get the same app as everyone else, plus our gratitude. Contributions fund new features.
