Fish Log turns your catches into an edge on the water. Most fishing apps are either a social feed or a generic forecast that tells every angler the same thing. Fish Log is different. It learns from your catches and tells you what actually works for you. LOG EVERYTHING THAT MATTERS Record your catches with GPS, species, weight, length, lure, technique, depth, and structure. Fish Log automatically pulls weather, water temperature, and barometric pressure so you are not fumbling with your phone. Log a full trip or a quick catch in seconds, even by voice. MEET LUNKER, YOUR PERSONAL READ Lunker studies your entire catch history and finds the days that looked just like today. Then it tells you what worked on those days. Same time of year, similar pressure, similar conditions. The more you log, the sharper Lunker gets. You also get a 7-day outlook so you can plan trips around the days that have historically fished best for you. SEE YOUR PATTERNS Detailed stats break down your best baits, colors, techniques, and the lure-and-technique combos putting fish in the boat at each lake. Spot your most productive depths, structures, and conditions at a glance. EVERYTHING IN ONE PLACE - A tackle box to save your go-to setups - A trophy room for your personal bests - A full map of every catch you have logged - Official structure and habitat markers - Log a skunk to track the tough days too, because what does not work is data - Works offline on the water and syncs when you reconnect YOUR DATA BELONGS TO YOU Fish Log is private by default. No public feeds, no leaderboards, no shared spot maps. Nobody can see where you fish or what you catch. Export your entire catch log to a spreadsheet anytime, and import your history from other apps so switching does not mean starting over. Built by an angler, for anglers. Download Fish Log and start turning your time on the water into your sharpest tool.
