FishTrack vs Submarius.

Who should use FishTrack?

Offshore tournament crews, charter captains targeting tuna / marlin / mahi, and anyone whose trips hinge on finding the temp break at the right depth. FishTrack's cloud free SST compositing is the output of years of satellite image processing (they fill in where clouds obscure single pass data) and that's genuinely hard to replicate. The chlorophyll layer for offshore color changes is equally strong.

If you're running 30+ miles offshore with canyon fishing or trolling weedlines as the game plan, FishTrack is in your kit for a reason.

Who should use Submarius?

Submarius is built for the coastal and inshore ocean user:

• Spearfishers and divers. Dive modes show a visibility estimate with a confidence figure next to current, swell and tide. It's a model estimate of how far you'll see underwater, not a measurement.
• Inshore anglers. The bite score weighs light, moonlight, how fast the tide is moving, water temperature extremes, and wind and waves. Each factor has its own row, so you can see what moved the score.
• People who do more than one thing on the water. Spear in the morning, fish in the afternoon, surf before dark. One app, and the verdict reweights for each activity.
• Anyone who wants safety features free. Safety Watch (a float plan with a "back by" time and SOS) and the shark awareness card in Spearfishing mode. No Pro gate on any of it, and Safety Watch needs a free account.
• Boaters who want reef and wreck structure overlaid on the map. More than 380,000 mapped reefs, wrecks, obstructions, dive sites and platforms as of August 2026, merged from NOAA charts, Florida FWC artificial reefs, BOEM Gulf of Mexico platforms, OpenStreetMap and a Wikipedia derived wreck list, with the sources shown on each one. It's a Pro layer, dense in US waters and sparse elsewhere.

The difference in one line.

FishTrack is the offshore SST tool for fishing. Submarius is the coastal conditions app for fishing, diving, spearfishing, boating and surfing, with tides, a bite score, safety tools and a verdict. Different jobs.

Can you use both?

Yes, and many serious anglers probably should. FishTrack for the offshore intel; Submarius for the inshore verdict, the dive or spear day, the safety tools, and one forecast for every activity you do. They don't overlap much.
