About this app

The most comprehensive trolling app on the market! Use it on the water to calculate your depth or use it at home to construct your own dive charts. 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.

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

I've been a loyalist since 2020. I would recommend this app for fishermen who are serious trollers. Pay attention to the list of lures in the app before you purchase so that you are not caught off guard. I gave it four stars because I recommend that the owner improve his glossary of terms and directions so future users learn how to interpret the results correctly. IMHO, better than Precision Trolling. PT shows much more line out for the same lure and line weight. Don't know why that is.

Great trolling tool. Much, much better than Precision Trolling and way less expensive. Trevor is super quick to answer questions or lend help when asked. This app will calculate line length for long line, lead core, as well as snap weights. You just enter the data and press calculate. I used the Precision Trolling app but was much more comfortable with Troll Master. It now has over or close too 100 different lure types and Trevor is adding more as they are tested. Buy it!!!!!!!!!!!

Works well, would like to be able to set line type, leader length, etc and have it be saved every time you open the app. Would save time while on the water and make the app now user friendly. Most of us are using the same basic setup for a whole season or whole trip.
