You finally dial in all the line, leader, and tip combinations that work best with your rods, conditions and casting ability. Now, fast forward to next season - your rigging up at the truck in the pre-dawn light and can't remember which line and tip goes with which, least of which whether or not you need T8 or T11 to fish this new intruder pattern on the run you are about to step in. Leader Builder ends that. Save the leader recipes that you actually fish on each of your rods. Add casting notes for what makes each one work. Next time you grip that rod at the river, the recipe is one tap away. Catalog every fly rod, line, leader, tippet, and sink-tip you own, then save the leader recipes that actually fish on each rod. Next time you grip that rod at the river, the right setup is one tap away. — What it does — • Catalogs your gear — fly rods (single-hand, switch, spey, trout spey), fly lines (integrated and shooting heads), commercial leaders, custom leaders built from butt + tapers + tippet sections, sink-tips, and tippet material. • Browse a curated catalog of common rods, lines, and tips so you don't have to type everything from scratch. • Build recipes — a line + leader + optional tip, tuned to a specific rod for specific water conditions (flow speed, target depth, fly type). • Save casting notes per recipe — what worked, what didn't, what to remember next time you fish this combo. • Find any recipe fast by rod or by gear. — Built for the river — • Fully offline. Your gear catalog and recipes work in the cell-dead canyon you actually fish. • Three sign-in options — Apple, Google, or email — so your data syncs across your devices. • No ads, no trackers, no analytics, no in-app purchases. • Free. — Whether you're — Swinging Intruders on a trout spey, throwing Skagit Mini Max on a switch rod, drifting dries on an 8-foot 4-weight, or matching a polyleader to a Skagit head — Leader Recipes captures the setup that makes each rod come alive on the water you fish. Tight lines.
