Essential for tournaments

GeoPelagic is an incredible tool for planning offshore trips and fishing tournament strategy. It has the best data and interface of all the fishing apps I have. The speedometer and live updating distance to waypoints are handy. The track of where I’ve been on the chart is very helpful. The premium account is definitely worth it - saves me time and fuel out there. My only complaint is that it takes a pretty experienced angler to figure out how to use it well, not for rookies but can make a good captain great. 5 stars.

All the tools you ever need to sport fish right here

I always knew water temp was the best way to find the fish that I was seeking however with this app you can even take into account things like chlorophyll concentration and avoid areas that might be too chlorophyll dense and impacting visibility. You can chart a course in the app and can even get data for across the whole globe - other apps are limited to what regions it covers. Download it now and you’ll have the only tool you need to find the fish.

Love the data, cleanly displayed

It's a big ocean, and I'm tired of burning fuel trying to guess where the school we saw last week has gotten to. A buddy recently turned me onto some of the science around surface temps and bathymetry. I'm pumped to give this a try next time out. Seems really user friendly so far planning from land.
