Free while in pilot
Know exactly what's in every fly box you own.
Fly Keeper is an inventory tool for anglers with more flies than memory. Catalog each pattern down to the color, hook size and count — then find it in seconds when the hatch is on.
What it does
Boxes, the way you actually store them
Set up a box for spring creek dries and another for the flats. Each one gets an icon and a color so you know it at a glance.
Track colors and sizes, not just names
A Woolly Bugger isn't one thing. Record olive #8 ×6 and black/olive #6 ×3 separately, with split-circle swatches for multi-color patterns.
Count up or down streamside
Tap plus or minus as you tie one on or lose one to a tree. Your counts stay honest without a spreadsheet.
Your own photos
Add a photo per fly from your camera, or bulk-import a folder and let filenames match themselves to your patterns.
A pattern library that learns
Start typing and 80+ classic trout and saltwater patterns autocomplete. Names you invent are saved to your own library.
Show a friend your box
Send a friend request and browse each other's collections — read-only, friends only, never public.
About the pilot
Fly Keeper is early and entirely free. Accounts are limited to three fly boxes while we find out what anglers actually need — everything else, flies, colors, photos and friends, is unlimited. Paid tiers with more boxes will come later, and nothing you build now will be taken away.
It runs in your browser and installs to your phone's home screen, so it works at the water without an app store.
