The whole water.
On one map.
Depth under the water, grass on the flats, where the bites have been, the spots people fish, the Slams running and the shops nearby. Turn on what you need and leave the rest off.
The map in Cobia, the free fishing app, puts your water on one screen. You turn layers on and off from one sheet: depth contours, seagrass and oyster habitat, structure, Strike Zones, wind, radar, a catch heatmap, named waters, Slams, tackle shops and spots. Tap a water to see its catches, species and Slams, and filter the catches by species and time.

One sheet runs the whole map
Every layer lives in one sheet at the bottom of the map. Nothing floats over the water but search and your location. Flip a switch here and the map beside it changes, the same way it does in the app.
Sample map. The layers are drawn the way the app draws them, over a stylized inlet. Depth is shaded in the app's twelve depth bands.
Every marker means one thing
The color says what state a place is in. The shape says what it is. A water you could take a crown on looks different from one nobody has fished yet, at a glance, from across the bay.
Blue once anyone has logged a catch on it.
Slate until somebody logs a catch on it.
Gold with a crown on the rim when someone holds it.
How crowns workGreen dots, and a disc with the count where they bunch up.
A triangle, the chartplotter waypoint, colored by what the spot is.

From Home, the busiest waters near you are numbered. A pulse means number one is hot this week.
Every water has a page, and its spots are in it
Tap a badge and the water opens with its latest catches, the species people land there and the Slams running on it. Its Spots tab lists the places inside it, rated by the anglers who fish them.

Sample heatmap. All Time. Every logged catch counts the same.
Where the bites have been, lately
The heatmap is built from catches anglers logged. Pick a time range and the older catches inside it fade, so last week reads hotter than last spring. Pick a species and only that fish is drawn.
- Five time ranges, from All Time down to the last 7 days. Try them on the map.
- One species at a time, from the fish people are catching near you.
- Drawn where the angler chose. A catch shared as a water or a rough area is placed at that public point, never at the real one.
Questions about the map
What layers does the Cobia map have?
Depth Contours, Habitat (seagrass and oyster), Structure and Strike Zones for the water itself. Wind and Radar for the weather. A catch heatmap, named Waters, Slams, Shops and Spots for what's on it. Each one switches on and off on its own in the Map layers sheet, and the base map switches between Map and Satellite.
Does the heatmap show other people's exact spots?
No. Each catch is drawn at the public point its angler chose to share. A catch shared as the water it's on or as a rough area adds to the picture without pinning the real spot.
Who can see a spot I add?
You choose for each spot. Private means only you, and nothing about it is published. You can also show only the water it's on, a rough area, or the exact spot. Public spots can be rated by the anglers who fish them.
What do the marker colors mean?
A blue water badge means someone has logged a catch there, slate means nobody has yet, and gold with a little crown means someone holds that water's crown. Green dots are catches, triangles are spots colored by their kind, the navy and gold disc is a Slam and the copper one is a shop.
Is the map free?
Yes. Every layer, Strike Zones included, is free in Cobia on iPhone and Android.
