Dipsy Troller

Working on a new version

I was too busy to update again the last version. I finally get some time and resources to built a brand new version with Flutter.

Last Version

As of April 28th, 2017, I have finalize and get accepted by Apple Store.

I apologize for all those who were waiting for this. I did the first version as a test of development and then tried many times to make a new version with different tools when I add some spare time.

I takes a lot more efforts than it looks like to have a version of this fairly simple app working on different size of screens and processor.

The new version offers a very cool new look interface with two themes, black and white, and as been tested on iphone 4s/iOS 9.3, iPhone 5, 5s, 6 and 7 with iOS 9 and 10.

Dipsy Troller is an iPhone App for fishermen. It shows the length of line for the depth you want to reach with fishing divers like Dipsy Diver, Jet Diver, Pink Lady or lead core line used to fish walleye, salmon, trout, lake trout.

As a fisherman myself, I was always searching for the charts and either I can’t find them, or they’re soaked with water. Don’t misunderstand me, all my tackle boxes are well organized but these tiny sheets of paper have no place in them. So I have designed this app for all of us who can’t find the charts. More seriously, while driving the boat it’s not always easy to find the right value in the chart and to calculate all of the other variables, speed and line.

The app has been designed to be fast and easy to use. Select the diver and slide the cursor to choose the depth, it will give you the length of line to take out of the reel. That’s it!


The app has been designed for 14 divers:

  • the 5 standard Dipsy Divers from Luhr-Jensen
  • the Magnum Dipsy Divers from Luhr-Jensen
  • the 4 Jet Divers from Luhr-Jensen
  • the 3 Pink Lady from Luhr-Jensen
  • any Leadcore line

I will add any other divers or diving systems, if you send me the photos and charts.

Other parameters

To calculate the optimum length of line the app use more variables:

  • the speed of the boat
  • the line type
  • for the dipsies the position of the directional sinker
  • also for the dipsies the use of O’Ring or not

Language and units

You can choose your language

  • french
  • english

You can also choose the speed and length units :

  • for speed: kilometers per hour (km/h) or miles per hour (mph)
  • for length and depth: meters or feet
