About this app

This app lets you select your line, your lure, a diver or trolling weights, and then combine them however you want. Quickly and easily see the effect of changing line length, speed, weight, leader length, rod height, lures and many other factors.

The app is continually improved and new lures and tackle are added regularly. This is a great app for anyone who fishes in saltwater, freshwater, or anywhere in between. The app has many features for walleye, trout, salmon, striped bass, red drum, tuna, wahoo, and pretty much any other species you might troll for.

This app uses physics based calculations to determine the trolling depth of your lure with precision based on your inputs. The calculations have been verified via on the water testing.

Ratings and reviews

DO NOT BUT! They no longer update new baits. They added fluorocarbon line in the last three years. Excuse after excuse and They will not refund or add baits. Updated April 8, 2024. I've been waiting for a single bait update for 3 years. This is a scam. Do NOT BUY!!!

I've had this app for a couple years now. I love it. I troll Lake Erie every spring, and summer. The app has definitely made a difference. I've used other apps such as precision trolling, and I find this app to much more user friendly. When I'm setting lines out I want the information I need quickly, and this app has been the trick. I've asked for lures to be added, and by the next season they're added along with a polite response. I would recommend this app to anyone.

I emailed since my lifetime purchase is telling me I no longer have access you told me to download again from app store or through restore purchase and tried both and still not working. I see the new version that you want me to pay for again and I will not since I already purchased once. Instead of updating the current app. You created another one with all of the current needed info but made excuses not to update the old version for your loyal customers. Shame on you.
