Your AI fly-fishing assistant

Know what to tie on.

Tell FishFly where you're fishing. It ranks the flies, builds the rig and plans your day — then saves it all to your phone, because good water rarely has good signal.

How it works

Ask. Tie on. Fish.

No forums, no hatch charts, no guessing at the fly shop counter. FishFly reads the water, the season and the light — you get flies with reasons.

STEP 1
Ask like you'd text a buddy

Name the water, or let it use your location. Plain English is the whole interface.

STEP 2
Get flies with reasons

Ranked patterns with hook sizes and why-lines that read like a river report.

No.1 Dry 5X
Elk Hair Caddis #16
Caddis come off early — fish the foam lines before sun hits the water.
STEP 3
Fish it offline

Every answer saves as a trip pack the moment it loads. Canyon water, zero bars, full plan.

The trip pack

Everything a good fly shop would tell you

Not just a fly list. Every ask becomes a saved pack — ranked patterns, the rig to build, and a plan that follows the light.

A plan for the whole day

Morning, midday, evening — flies and tactics shift as the light does.

The rig, knot by knot

Leader length, tippet size, trailer spacing — spelled out, not implied.

Built for dead zones

Packs save automatically and re-open instantly. The best water has the worst signal — FishFly plans for it.

A one-tap check-in after the trip puts the day in the books — how it fished, and what you netted.

From the beta

"Told me to trail an RS2 behind my caddis. First run, brown on."

Angler · Deckers, CO

"The day plan is the feature. I stopped second-guessing myself at 2pm."

Angler · Frying Pan River

"No signal in the canyon all day. The pack didn't care."

Angler · Cheesman Canyon
