Fish where they are. Not where they were.
Preparation eliminates guesswork. Temperature contour lines no one else draws, view your competition, 7-day playback — point your boat in the right direction before you leave the dock. Starting at $9.99/mo.
CATALYSST is real-time fishing intelligence — a blend of catalyst and SST (sea surface temperature).
Yes — spelled with a double S, on purpose. Not the word “catalyst.” Catalysst overlays live AIS vessel traffic with satellite sea surface temperature and chlorophyll charts, so you leave the dock knowing where the fish are — not where they were.
Real-time vessel traffic. Real catch data. Where the fish actually are.
Other apps show you yesterday's satellite gradient. We show you the temperature break, the vessel traffic on it, and 7 days of how it moved — so you leave the dock knowing where to go.
The fishing ingredients no other app combines.
Each one is an ingredient. Together they save you time, save you gas, and put you on fish — at a fraction of what the legacy services charge.
SST Charts
Find the temperature breaks tuna and dorado stack on. See where the warm water is now and where it's been moving — so you point your boat in the right direction before you leave the dock.
Chlorophyll
Spot the green-blue color edges where bait holds. Bait concentrations and productivity zones jump off the chart — when you commit gas, you commit it to fish.
Live Vessel Traffic
See exactly where your competition is right now. Real-time vessel positions, speed-colored trails, 72-hour playback. If they're catching, you'll know where.
GPS Waypoints
Tanner, Cortez, the 295, the Upper 500 — all preloaded. Drop your own marks, plan routes in nautical miles, share spots with your crew.
Raw Satellite
Unfiltered satellite passes with cloud gaps visible. See exactly what the sensor saw — no interpolation hiding the real ocean from you.
Contour Lines
Temperature contour lines no one else draws. Discrete edge lines layered on the SST gradient — see the breaks at a glance, find where bait and predators stack.
Satellite Data,
Rendered Live
Toggle between sea surface temperature, chlorophyll, and live vessel tracking. Continuously refreshed throughout the day so you're always working from the latest available imagery.
Charts in the morning. Catches by sundown.
Fresh ocean charts on your phone every three hours, around the clock. We do the heavy lifting so you can leave the dock with a plan.
SoCal Fishing Intelligence
Spotter-plane tracking and the verified-catch map ship only in the SoCal version, layered over the same temp breaks, chlorophyll edges and live fleet AIS. In the Santa Catalina Channel it put members on fish a full day before the sportboat fleet reached the same water.
Two layers you won’t find anywhere else.
Satellite water is table stakes. These two come from people — pilots in the air and anglers on the water — and they only ship in the SoCal app.
Somebody flew out and circled this water
Fish-spotting planes work the Bight every day. When one stops and orbits a patch of ocean, the pilot is looking at something — bait, breezing fish, a paddy. We track that flight activity and draw the zones they circled straight onto your chart.
On the live chart, swordfish spotters draw in purple and every other spotter draws in green, each on its own toggle — so you can tell a broadbill orbit from a tuna orbit at a glance.
Real catches, pinned where they actually happened
Every fish icon is a verified catch plotted at its real position — not a rumour, not a screenshot of somebody's dock talk. Colour shows how fresh it is, and tapping a pin gives you species and timing.
Lay it over the temperature break and the fleet's stop circles and the pattern shows itself: the catches stack on the edges, and you can see the bite move day to day.
Spotter-plane AOIs and the confirmed-catch map are part of the Southern California subscription. They are not included in the US or International versions. See the full SoCal guide.

Live vessel traffic. Custom watch list. 7-day playback. Buoy temps. Contour breaks. No other chart service in our comparison has all five — here they come bundled for one price.
Live vessel traffic + 72h playback
Watch your competition right now. See where they were drifting yesterday. Spot the bite before it ends.
Custom 50-vessel tracker
Your watch list. The boats you actually care about, not 5,000 commercial ships filling the screen.
Contour break overlays
Temperature breaks as crisp discrete lines. Find the edge faster, not gradient guesswork.
7-day chart playback
Scrub backwards. See where the temp break has been moving and where the green water shifted.
Live NDBC buoy temps
Real ocean temps from real buoys. Not satellite estimates filtered through cloud cover.
US + Intl coverage
PNW → NE for US. Mexico, Central America, Caribbean. One subscription, every coast you fish.
Satellite SST and chlorophyll, and on most a look back at earlier images. No live vessel traffic, so you guess where the boats are, you guess where the break moved, you spend the morning pinpointing what already happened.
Live AIS shows where your competition is right now. Your custom ring tells you the moment your watch boats stop. 7-day playback shows where the temp break has been moving. Buoy temps confirm satellite. You leave the dock knowing where to go.
Better data. Half the price.
