How Hackle Tracker Works
The short version: log what's on your bench, see what you can tie. Here's everything else worth knowing.
Catalog Note
The pattern catalog is actively improving. Recipes and material mappings are useful as a practical starting point, but some patterns are more complete than others and fly tying always leaves room for variation, substitutions, and personal preference.
The Idea
Hackle Tracker is an inventory app, not a recipe book. You tell it what materials you own, and it tells you which fly patterns you can tie right now — and which ones you're one or two purchases away from.
The loop is simple: check off materials → see your patterns → tie flies. Everything else builds on that.
Your Materials Page
Checking things off
Tap any material card to toggle it owned or unowned. Categories are collapsed by default — tap the category header to expand it. Use the search bar to jump straight to anything.
Adding detail with trait chips
Once you own a material, a small details button appears on the card. Tap it to log specifics — colors you own, sizes, hook styles, bead finishes. This is optional but it sharpens your pattern confidence from "I probably have this" to "I have exactly what this pattern needs."
The confidence badge
On the dashboard, some Ready to Tie patterns show a ✓ confirmed badge. That means you've logged specific traits — colors, sizes, finishes — for the materials that pattern needs. No badge just means you own the right categories but haven't verified the details yet. Either way you can tie the fly — confirmed just means you're certain before you sit down.
New user? Start here
If your bench is empty, Midge will suggest five starter materials at the top of the page. They're the five that unlock the most patterns fastest: Nymph Hook, Thread, Tungsten Bead, Superfine Dubbing, and Wire. Check them off and you'll have a real list of patterns to work from before you close the tab.
Your Dashboard
The dashboard has three tabs. They're all doing different things.
Ready to Tie
Patterns where you own every required material. Tap any card to see the full recipe, watch a tutorial, log it, or add it to your queue.
Almost There
Patterns where you're missing one or two required materials. These are your shortest path to more flies. Midge's "Can I substitute X?" button lives here — ask him if something on your bench can stand in for what you're missing.
Buy One
Materials ranked by how many new patterns they'd unlock. The tab header shows the total unique patterns you'd open up if you bought the full list — so you know exactly what's at stake. The top card gets a 🔥 badge for the single purchase that does the most work. Add anything to your shopping list directly from here, and Midge will drop a quick take when you do. The "Should I buy this?" button gives you his full read.
Search
There's a search bar across all three tabs. Type a pattern name to filter down to just that fly — useful when you know what you want to tie and want to check if you're close.
The ⚠ Check stash status
This shows up on patterns where you own all the required materials but one of them has a trait conflict — wrong color, wrong bead finish, wrong hook size. The card shows the specific materials involved so you know at a glance what to look at. Click through to the pattern page to confirm the traits you do have, or hit Tying it my way if you're not worried about the mismatch and want the pattern counted as ready.
Bench score pills
Below the search bar, a row of colored pills shows your readiness for each fly style — Dry fly 78%, Nymph 45%, Streamer 31%, and so on. The fill inside each pill represents the percentage of patterns in that style you can currently tie. Color tells you your strength level: green is Excellent (85%+), teal is Strong, amber is Solid, orange is Building, red is Developing, and gray is Weak. Tap any pill to filter all three tabs to that style. Tap again (or tap All) to clear it.
Pattern Detail Pages
The recipe
Every pattern page shows a full material list sorted in tying order — hook first, thread, body, rib, wing, hackle, and so on. Each material shows its role in the fly (body, tail, rib, etc.) so you know exactly what it's doing and why.
What you're missing
If you can't tie the fly yet, there's a callout box at the top showing exactly what you need to buy, including hook size recommendations for beads.
Readiness callouts
If you own most of the materials but have some trait mismatches — wrong bead finish, wrong hook size — the pattern page calls those out specifically. For hook sizes, you'll see individual chips for each size in the recipe so you can confirm exactly which ones you have. Confirm the traits you do own and the badge updates instantly.
Adding to your inventory from the pattern page
Each material row has a small + I have this button. Tap it to add that material to your inventory without leaving the pattern. The + List button adds it to your shopping list.
Pattern photos
Most pattern pages have a swipeable photo strip showing what the finished fly actually looks like — useful when you're not sure if your version is on track. Community members can submit their own tied examples using the Submit a photo prompt at the bottom of the strip. Photos go through a quick review before they appear.
Logging and queuing
Log it records that you've tied this pattern — it goes into your tying history and triggers badges. Queue it adds it to your tying queue so you can plan a session in advance.
Suggest a fix
The material list isn't always perfect — fly tyers have opinions. If you spot something wrong, hit Suggest a fix at the bottom of the pattern. It goes to a review queue.
Browse Patterns
The Patterns page shows every pattern in the catalog with your match status on each one. It's useful when you want to explore what's available rather than just see your current matches.
Filters
Filter by fish species (trout, carp, bass, panfish), fly type, difficulty, water type (stream, tailwater, stillwater, spring creek), and season. Filters stack — so Nymph + Stream + Spring shows you exactly the flies that fit a spring creek nymph box.
Your status on every card
Each pattern shows your match status — Ready, Likely, Check stash, or how many materials away you are. So even while browsing you can see at a glance what you can tie and what's just out of reach.
Midge — Your AI Companion
Midge knows your bench. Every question he answers is informed by what you actually own — he's not giving you generic fly shop advice. He has opinions, a dry sense of humor, and a neighbor named Carl who makes questionable decisions at the vise.
Should I buy this? — on the Buy One tab
Ask Midge whether a material is worth purchasing. He'll tell you what it unlocks, why those patterns matter, and whether the buy is a no-brainer or a luxury. He'll also be honest when it isn't worth it.
Can I substitute X? — on the Almost There tab
Give Midge the missing material and he'll look at your bench and tell you if anything you own can stand in for it. Real substitution advice — not guesswork.
What should I tie? — Ask Midge box at the top of your dashboard
Describe your fishing situation — river, conditions, time of year, target species — and Midge picks 3–5 patterns from your ready list that fit. Be specific and you'll get specific answers.
Free accounts get 5 Midge queries per month. Pro gets full access.
Shopping List
Your shopping list lives at Shopping List in the nav. Materials are grouped in shop-walk order — hooks first, then thread, beads, dubbing, and so on — so you're not zigzagging around the store.
Adding items
Add materials from the Buy One tab or Almost There tab ("+ List" on each card), from pattern detail pages ("+ List" on each material row), or directly from the shopping list page itself.
Pattern unlock info
Each item on your list shows which patterns it would unlock if you bought it. So you can prioritize at the shop based on what opens the most new flies.
Shareable link
There's a share button on the shopping list page. It generates a link anyone can view — useful for sending your list to a spouse, a fishing buddy, or your own phone before walking into a fly shop.
Tying Queue
The queue at Queue is for planning a tying session before you sit down at the bench.
Adding patterns
Add any pattern from its detail page using the Queue it button. You can set a quantity and a color note — useful when you're tying a batch of the same fly in different sizes.
Tied it
When you finish a fly, hit Tied it on the queue card. It logs the tie automatically and removes it from the queue. No double entry.
Tying Log & Badges
Log
Every time you log a pattern — from the detail page or the queue — it goes into your tying history at Log. Volume, variety, and streaks are all tracked.
Badges
Badges are earned automatically when you hit milestones — first tie, 10 patterns logged, tying multiple species, hitting variety targets. They show up as a toast notification immediately when you earn them, wherever you are in the app. Check your full badge collection on the log page.
Things Worth Knowing
- The pattern catalog covers trout, carp, bass, and panfish. Use the species filter on the Browse Patterns page to narrow it down.
- Materials are broad categories, not specific products. "Tungsten Bead" covers all tungsten beads — the trait chips are where you log your specific sizes and finishes.
- Pattern recipes are a starting point, not gospel. Every tyer has variations. The Suggest a fix button exists because we know the list isn't perfect.
- The "Almost There" tab is often more useful than "Ready to Tie." It shows you the fastest path to more flies, not just what you can already do.
- Midge gives better answers when you give him more context. "I'm fishing a spring creek for selective browns during a PMD hatch in low clear water" beats "trout fishing."
- When you check off a material that unlocks 3 or more patterns at once, you'll get a full-screen celebration showing exactly which patterns just opened up. Each one is a link straight to the recipe.
- Free accounts can track materials, keep a starter tying log, and use Midge 5 times per month. Pro unlocks the full ranked buying intelligence, smart queue, unlimited logging, and unlimited Midge.
- Your tying history is public — shareable at
hackletracker.com/u/username. Set your username from the Account page. Useful for flex purposes, or for sending someone who asks what flies you actually tie.
