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!

Doesn’t work in some configurations.

Doesn’t work unless you select a pre-loaded lure option or diver. For example, you can’t enter custom inputs for something like lake trout where you might use a mega jig weighing an ounce or more, combined with a 4 or 8 oz trolling weight (fishing from a kayak, not using downriggers. This configuration using a 4 oz weight and 100 feet back results in a 40 foot depth.) When you hit ‘calculate’, it says ‘No results found; enter a diver or trolling weight’, even though you have already entered the trolling weight. Could be just a minor bug that needs to be worked out. Seems to work quite nicely if you enter a diver or pre-set lure. Wouldn’t have paid the $50 if I would have known this, however.

Developer Response
Thank you for your review. If you have selected a jig as the lure, please make sure that you enter the lure weight. I suspect this is the issue that you are finding. Please email us if you have any additional questions at trollingcalculator@gmail.com. Thank you!

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.Buddy K.

Best app out there for the water

Im an avid fisherman on many of the Great Lakes and smaller inland lakes chasing multiple species. This great app has all the lures i utilize and depth calculations to get me down to the fish. The app owner is very helpful and will answer any question you have. He is continually updating the database to include more lures. You can’t go wrong with this on the water. I purchased the lifetime membership and couldn’t be happier.
