> TROLLLOGIC BRINGS FISHING INTELLIGENCE If you troll, you know how quickly things can change. Change a lure or color. Speed up. Slow down. Let out more line. Change depth. Then a rod fires - and sometimes it turns into pure chaos. TrollLogic remembers which lures were on, the line-out for each rod, and what was working so you can get everything set back up. It recognizes what's working during the trip and saves it for the next time you're on the water. > START EVERY TRIP WITH A PLAN TrollLogic combines what worked on your previous trips with today's fishing conditions - moon phase, barometric pressure, water clarity and water temperature - to give you immediate startup lure and speed suggestions. Start fishing with setups that worked before instead of guessing - or trying to remember which lures and speeds worked best the last time you were here. > SET THE CORRECT LURE DEPTH You can't catch fish if your lure isn't where the fish are. TrollLogic's Depth vs. Line-Out Calculator helps put your lure in front of or just above the fish. > SPOT REAL-TIME TROLLING PATTERNS As you log catches, TrollLogic looks for emerging patterns in speed, lure color, depth and line-out. When variables converge, TrollLogic identifies the fish-catching patterns developing in real time and alerts you. It even suggests setups for other rods so you can take advantage of what's working while the fish are biting. > TRACK EVERY CATCH AND WHERE IT HAPPENED Log each catch with its rod, lure, depth and fishing conditions. TrollLogic records the exact GPS location and your trail, showing what caught fish and exactly where it happened - so you can return to that spot. Whether trolling, reef fishing, casting for bass or tarpon, or ice fishing in the frozen north, TrollLogic remembers where you caught them. Every trip becomes part of your fishing history library - ready when you come back. > SEE THE BOTTOM CONTOURS YOU'RE FISHING TrollLogic includes detailed contour mapping for all the Great Lakes, supported coastal waters, and select inland lakes. We'll continue expanding mapping coverage as new areas become available. Use the maps with your live GPS position, trail and catch locations to see the bottom contours you're fishing, where you've been and where your fish were caught. > SHARE THE WHOLE TRIP Send another TrollLogic angler the whole trip - including catches, photos, trip details, GPS trail and waypoints. Instead of explaining what you were running or where the fish came from, just send them the trip. > NOT JUST FOR TROLLING Built around trolling, TrollLogic doesn't stop when the trolling rods come in. Casting, Spot/Anchor - including Ice Fishing - and River Drift modes let you record and remember those trips too.

Finally: A journal that fishes back. Most fishing apps show you the weather and someone else's catch photo. WaterWatcher tells you what the fish are doing — and learns from every trip you take. Speak naturally — and WaterWatcher captures everything: species, tactics, what worked, what didn't, plus 20+ environmental conditions, automatically. The platform learns what produces fish at your spots. Every trip makes the next one sharper. Built for every angler and every water — bass, trout, striper, tarpon, redfish, walleye, and more, from farm ponds to offshore canyons. SPEECH-DRIVEN TRIP CAPTURE Log on the water, in the truck on the way home, or back at the dock — whenever it's easiest. Just talk, and WaterWatcher converts your natural speech into structured field data: catches, sightings, observations, and conditions, without typing a single word. NOW ON APPLE WATCH Leave your phone in your pocket. Start a trip, log a catch, and end your session — all from your wrist. WaterWatcher's Watch companion captures voice recordings and GPS location in the moment, so nothing gets lost between the bite and the write-up. REAL-TIME CONDITIONS INTELLIGENCE Every trip captures a full conditions envelope: water temperature, tide state, tidal range, barometric pressure trends, moon phase, wave height, solunar periods, and chlorophyll proximity. The data you need to understand why fish were where they were. THE READ: YOUR OWN PATTERN ENGINE The more you log, the smarter it gets. WaterWatcher builds a personal pattern model from your own catch history — tide, pressure, and solunar cycles, tuned to your spots and species. See your best windows before you leave the dock. INTERACTIVE MAPS Sea surface temperature (inshore or offshore), chlorophyll, depth contours, and your personal catch history — all on one map. See where the water breaks and where you've caught fish before. CONSERVATION THROUGH CITIZEN SCIENCE Every trip contributes to the WaterWatcher LEDGER by default, supporting fishery research. Your catches, sightings, and field observations, even shark and pinniped predation events. Your data becomes part of the scientific record. Opt out anytime in Settings. OUTSMART THE CONDITIONS. OUTFISH THE CROWD. PROTECT THE FISHERY. Free to start, with tiers for anglers who want more.
