Flybox
Know what's already in the box — and what you're short before you sit at the vise
Build a visual inventory of every fly box with per-compartment pattern counts, write a recipe card for each fly listing hook, bead, thread, dubbing and hackle, and Flybox joins the two into a living materials shelf with low-stock flags and a restock list. Free, offline, no account.

What you can do in Flybox on the web
Visual fly-box inventory
A coloured compartment tile per box, tagged to a river or season, holding the patterns you have tied with a count for tied and a count for fished.
Recipe cards with every material
Hook, bead, thread, dubbing, hackle, wing, tail, rib, body and wire — each line joined to a real item on your shelf, with a per-fly quantity.
The derived materials shelf
Recipes joined against on-hand stock: every material shows how many recipes call for it and whether it is under your restock line.
Tie-now or short a material
Each pattern says whether every material it needs is on the shelf, or names exactly what you are missing — before you sit down, not after.
Restock list you can take to the shop
Low materials grouped by category with tick-off checkboxes, per-material thresholds you can tune inline, and a CSV export.
Stays on your device
Boxes, recipes and shelf live in this browser only — no account, no cloud, nothing synced.

Questions
Is the web version of Flybox free?+
Yes. Every screen is free to use: no subscription, no in-app purchases, no account.
Do I need an account?+
No. Open Flybox and start using it right away. Sign in with Google only if you want to upvote an app, save it to your list, or leave a comment.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Is there a Flybox app for iPhone or Android?+
Not yet. Flybox is a community proposal: the browser version is complete, and we build the iPhone and Android app once 100 people upvote it. Upvoters get one email when it ships.
