Drop a pin on any US water and Sounder tells you what to throw, when to go, and why. Everything about the water is free: no account, no ads. Drop a pin on any water in the US. Sounder tells you what to throw, when to go, and why. A tidal creek, the surf, a reservoir, a farm pond, a kelp bed. Sounder reads it: what kind of water it is, which fish are likely there right now, the one bait to tie on, and exactly how to work it. EVERYTHING ABOUT THE WATER IS FREE Not a demo, not a trial. The map, live conditions, bite windows, the full species guide, and your entire catch log are free, with no account and no ads. Sounder Pro adds depth on top for people who fish hard. It never takes anything away. TODAY, AT A GLANCE The day's tide curve with your bite windows drawn on it, live water temp, wind, sky and rain odds, plus a two-day trip planner that says when to go, honestly. If the day is slow, Sounder says so and points at the next good hour instead of inventing one. A GUIDE IN YOUR POCKET 96 species across every US region, from pond bass to canyon tuna, each with real seasonal knowledge: rigs, techniques, tackle, best tides and light. Backed by live NOAA tides, marine forecasts, barometric trend, water clarity, and solunar feeding windows, plus an AI briefing that talks you through the spot like a guide on the bow (5 fresh AI reads a month; re-reading one you have already pulled is free, and every other feature is unlimited). IT LEARNS YOUR WATER Every catch you log is silently stamped with the exact conditions. The Log turns your history into a species leaderboard with personal bests, shows which lures actually produce, and mines your patterns ("7 of 9 redfish came on falling tides"), then stars the upcoming windows that match how YOU actually catch. Built from your fishing, not a crowd average. NO ACCOUNT. NO ADS. NO FEED. Nothing you save is ever shared with anyone, and there is no public map of anybody's spots. Your log exports whenever you want it. Optional sync if you fish from two phones. Also in the box: search any lake, river, or ramp by name; the next good window at each of your saved spots; nautical charts (NOAA), live rain radar, satellite sea-surface temperature, wave forecasts, a depth layer, and artificial-reef pins nationwide; per-state regulations links, keeper-slot flags, catch photos, personal bests, and a shareable "read" card that never reveals your coordinates. Sounder covers US waters: Atlantic, Gulf, Pacific, Great Lakes, and every pond, river, and reservoir in between. SOUNDER PRO — OPTIONAL Everything above is in the free app. Pro adds the Daily Fishing Report — weather, tides, sun & moon, your top five best bets with their baits, and the day's best windows, composed for YOUR spots every morning — plus unlimited AI reads, a 7-day planner with AI trip plans for every saved spot, bite alerts matched to your own patterns, per-species playbooks, seagrass & oyster-bed map layers from state and federal surveys, and your best bait by conditions, mined from your log. Monthly $3.99 · Yearly $24.99 · Lifetime $49.99 (one-time). Subscriptions renew automatically unless cancelled at least 24 hours before the period ends; manage or cancel in your App Store account settings.

New: Photo Fish Identifier Add a photo of your catch and Sounder tells you what you caught. And a batch of smaller app updates and improvements: • Size and slot limits now verified for all states. • Sharing a spot no longer attaches its coordinates unless you switch that on. • Jerkbaits and crankbaits are no longer treated as topwater, so cold-water picks make sense again. • Tide and solunar times show as actual clock times on Today. • Uncovered water says so plainly instead of showing an empty screen. • A Pro code can be redeemed right inside the app. • The app download is 82% smaller.
