The future of trolling!

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.

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.

Best app on market for cranking! Buy the lifetime version!

This app is very useful and easy to use! It far out weighs any other apps for this on the market. Plus it has way more options as the other apps and options like it are very limited! This is the only one APP you need! However keep in mind The app would not allow me to buy lifetime subscription at first! You must click purchase through the upgrade button at bottom of app after opening instead of through the settings app and subscriptions. As going into subscriptions it will only give you monthly and annual options! Hope this is helpful!

Great App for many trolling applications!

I use many of the trolling applications the App supports...I would like the app to accommodate leadcore as well then it would be a 5 star app. It is a good and simple tool to get you close. Just what I was looking for.

Developer Response ,

We now have leadcore. Thank you for your interest in the app!

Excellent customer support

I had a question so I sent an email to the developer and within hours the question was answered. On my iPhone some of the lures were super imposed on top of other lure types he suggested I reduce the magnification of my text size and that fixed the problem. Then I had a few more questions and his responses were virtually immediate.
This is a really excellent app for serious fishermen and it’s bound to only get better.
