The only app built for fly tyers to do it all — in one place.
From your first hook to your hundredth pattern, Woolly Bug keeps your whole bench organised and at your fingertips.
Track every feather, dubbing, hook and thread with photos, quantities and storage locations. Clone items and batch-add — your whole bench in one searchable library.
Search 650+ hooks from 14 brands by shank, gape, wire weight and eye type — and find equivalent alternatives in seconds.
Build shopping lists linked to your inventory. Mark items purchased and restock — so you never buy a duplicate spool again.
Cloud sync plus WiFi-direct between iPhone and iPad — your stash stays in step at the bench or the shop, even without internet.
Bulk-manage your inventory in Excel or Numbers, with smart de-duplication when you re-import. Your data, always yours.
Save your favourite fly recipes with full material lists, then see at a glance which patterns you can tie right now and which materials you're missing.
A warm, focused interface that feels right at home next to your vice.
Woolly Bug started at a cluttered tying bench, scribbled material lists, and one too many trips to the shop for a spool we already owned. It's the tool we wished existed — simple, warm, and made entirely around how fly tyers actually work.

Everything on your bench — hooks, threads, dubbing, hackle, feathers, beads, wire, flash and more. Each item supports sizes, colors, brands and quantities, so your records match real life.
Yes. Save your patterns with their full recipes and Woolly Bug cross-checks them against your stash, showing at a glance which flies you can tie and which materials you're missing.
Woolly Bug runs on iPhone and iPad with iOS 18 or later. Your inventory syncs seamlessly across devices, so you can add materials on your phone at the shop and browse patterns on your iPad at the bench.
