Sea Spotter

Sea Spotter is your real-time companion for discovering and sharing marine wildlife — dolphins, whales, orcas, and more — wherever you sail.

CROWDSOURCED SIGHTINGS
Report what you see and instantly alert other sailors nearby. Every sighting is shared in real time, so you always know what's in the water around you.

HEAT-MAP VISUALIZATION
Our unique probability heat map shows where marine animals are likely to be right now, accounting for time and species movement speed. The map updates live as new sightings come in.

REAL-TIME ALERTS
Subscribe to geographic zones and get notified the moment a sighting is reported in your area — even while the app is in the background.

SPECIES TRACKING
Browse sightings by species — bottlenose dolphins, common dolphins, orcas, humpback whales, sperm whales, and more. Each species has its own movement model for accurate probability mapping.

FOR SAILORS AND NATURE LOVERS
Whether you're on a sailing trip, whale watching tour, or just out on the water, Sea Spotter turns every boat into a citizen science station.
