Features

Everything a Crappie Fisherman Needs

Purpose-built tools that help you find, pattern, and catch more slabs on every trip.

Attractor Map

GPS coordinates for brush piles, stake beds, PVC trees, and pallets. The spots the locals don't share — color-coded and filterable by type.

Weather Dashboard

Barometric pressure trends, wind visualization, moon phases, and hourly forecasts — all tuned for crappie behavior patterns.

Lake Conditions

Real-time water levels vs. normal pool elevation, USGS stream gauge data, and generation schedules from TVA and Army Corps dams.

Thermocline Predictor

Water temperature stratification analysis that tells you exactly what depth crappie are holding at. No more guessing.

Bait Recommendations

Lure and color suggestions based on current conditions, seasonal patterns, water clarity, and what's producing right now.

Spider Rig Calculator

Physics-based depth calculator for spider rigging. Input sinker weight, line length, boat speed, and line type to hit the exact depth zone.

Attractor Map

The Spots the Locals Don't Share

Access GPS coordinates for fish attractors across multiple lakes — data sourced directly from state wildlife agencies. Filter by type, get turn-by-turn navigation, and fish the structure that holds slabs.

AI Fishing Assistant

Ask Uncle Slab

Like having a crappie fishing legend in your pocket.

Uncle Slab is your AI fishing buddy — the kind of old-timer who's forgotten more about crappie than most people will ever learn. Ask him anything. He's backed by a growing database of crappie fishing knowledge, scraped and updated nightly from the best sources on the water.

He's not a corporate chatbot. He talks like a fisherman because he was built by fishermen. No jargon, no fluff — just straight answers from decades of compiled crappie wisdom.

Uncle Slab, what's the best bait for stained water in March?
Uncle Slab avatar

In stained water come March, you want something they can see and feel. I'd go with a 1/16 oz chartreuse and orange tube jig — slow fall under a slip float set about 8-10 feet. The pre-spawn fish are moving up and they're aggressive. If tubes aren't getting it done, switch to a Bobby Garland Baby Shad in monkey milk.

What depth should I fish when the thermocline is at 15 feet?
Uncle Slab avatar

If the thermocline's sitting at 15 feet, your crappie are gonna be right at or just above it — that 12 to 15 foot range. Set your spider rig jigs staggered between 11 and 14 feet. The big ones like to suspend just above that break where the oxygen's still good.

Is the bite going to be any good this weekend at Reelfoot?
Uncle Slab avatar

Looking at the forecast — barometer's been steady, wind's supposed to lay down Saturday morning, and we've got a waxing moon. I'd rate it an 8 out of 10. Get out there early, fish the cypress stumps on the south end. They've been stacked up in 6-8 feet.

Smart Fishing Journal

Your Catches. Your Patterns. Logged in Seconds.

Most fishing logs ask you to type everything. SlabHaul pre-populates what it already knows — GPS location, lake name, weather, barometric pressure, water temp, moon phase, and time. You just fill in the fish.

Over time, your journal builds a personal fishing history that reveals patterns you'd never see otherwise. Which moon phase produces your best days? What bait works best when the barometer is falling? Your data, your edge.

  • Auto-populates location, weather, moon, pressure, temp, time
  • You only add: species, size, bait, and optional photo
  • Pattern analysis reveals your best conditions
  • Log a catch in under 10 seconds on the water

The attractor map is a game-changer. Found brush piles I've been driving over for years. Put us on a limit by 9 AM.

FAQ

Frequently Asked Questions

SlabHaul is the only fishing app built 100% for crappie. Every feature — from the attractor map to the thermocline predictor to the spider rig calculator — is designed specifically for how crappie fishermen think and fish. We don't try to be everything for everyone.

Our attractor data is sourced from state wildlife agencies including TWRA, AGFC, and KDFWR. These are official brush pile, stake bed, and PVC tree locations placed by fisheries management programs. We verify and format this data for easy navigation.

We currently have full attractor maps for Kentucky Lake (TN/KY), Reelfoot Lake (TN), and Horseshoe Lake (AR). Weather and water data is available for 85+ lakes. We're adding new lakes across the Southeast regularly — Pro and Guide subscribers can request priority lake additions.

Uncle Slab is our AI fishing assistant — built on a growing database of crappie fishing knowledge that's updated nightly. Think of him as the uncle who always knows more about crappie than everybody else at the ramp. Ask him about baits, techniques, conditions, or specific lakes and he'll give you a straight answer. He also voices the Morning Crappie Report.

SlabHaul is available on iOS, Android, and the web. Download from the App Store, Google Play, or use the web app at slabhaulapp.com.

Yes. Attractor locations, the knowledge base, and the spider rig calculator all work offline. Weather and water level data requires a connection to fetch the latest readings, but previously loaded data is cached on your device.

Yes. All beta testers get full access to every feature at no cost. Once we officially launch, you'll be able to choose the plan that fits your needs. Early supporters will receive special pricing as a thank you.
