Know the water before you get there.

Live flows, up-to-date playbooks, and a fly box grounded in real shop reports. Six waters on the board, and everything works with zero bars at the bottom of the canyon.

What it does

Flows that mean something

Every water shows its live CFS colored by what the number means on that stretch - the bands anglers actually fish by, not statistics - with two weeks of trend behind it. One glance and you know whether to drive.

A plan for the hour you're standing in

Each water carries a dated playbook built from current fly shop reports: a read on conditions, then concrete plays for morning, midday, and evening. Open it at 7am and it hands you the morning plan. Fresh playbooks land all season.

What do I tie on first?

The fly box leads with the patterns this week's playbook calls for, in priority order, then the rest of what's in season. Every fly is a real, buyable pattern, hand-painted in watercolor, with honest notes on how it fishes. Nothing is invented.

Offline first, actually

Cheesman has no bars and the app doesn't care. Playbooks, flies, art, and plans all live on your phone; updates slip in quietly whenever you have signal. The only thing that needs service is the live gauge, and it fails silently, never in your way.
