See the drop-offs before you launch

Warm is shallow, cool is deep. The shelf, the hump and the channel edge stand out before you touch the water, so you go where the fish hold instead of driving around looking for it.

Know what you caught, and where it came from

Every catch pins to the spot it came out of, at the depth you were fishing. Fish one lake for a year and the map turns into your own record of what lives where.

Never lose a good spot again

Mark it once and it's waiting for you the next time you launch. No notebook, no pin dropped in some other app, no lining a tree up with a dock and hoping. It's just there.

Works with or without a signal

Everything you need on the water works offline, because the whole lake is already on the phone. Get back in range and the photos, the chat and the people are waiting for you.

Out on the waterBack in signal
  • ✓

    With no signal at all

    The map, live GPS, depth on every contour, and every mark you've saved.

  • ✓

    When you're back in range

    Photos of what you caught, the anglers near you, and everything they're pulling in.

Nothing on the water waits on a connection

Fishing is better with friends

There are anglers on your lakes right now looking for someone to go with. Some have a boat and no partner. Some know water you've never launched on.

Good to know

The short version of the things worth knowing before you rely on it.

Before you rely on it
  • It's not a navigation aid. Bathymetry is survey data of unknown vintage. Hazards, obstructions and water level aren't mapped. Don't navigate by it.
  • Fishing regulations. Size limits, bag limits and seasons vary by state and they change. The app never states them. Check your state's current regulations.
  • It doesn't predict fish. No score, no forecast, no model guessing at your odds. It shows you the shape of the bottom and the record of what you caught. The rest is fishing.
