Troll app and customer support

Best trolling app I’ve seen and used, numerous lure brands to choose from. I purchased the lifetime subscription on an android phone switched to apple contacted support and received a code to transfer membership, big props to them. Highly recommend app and good support!

Best app for trolling and phenomenal customer service

Very in depth and accurate. Many options from line type speed lure even divers. I bought the lifetime edition a while ago. Unfortunately, that was on my android and the purchase wouldn’t transfer to my iPhone. I wrote a quick little email to the developers and they quickly gave me a gift card code to redeem my lifetime membership on my iPhone. Big time kudos to this app.

Add saltwater lures please!

Too few saltwater trolling lures from Yo-Zuri, nothing from MagBay or Ilander, which are most popular in Florida!

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.

Response from developer

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!
