Free Marine Chartplotter · US Coastal & Great Lakes
Ditch the subscription. Keep the charts.
When other anglers accuse you of hogging all the fish.
FishHogs puts free NOAA nautical charts and GPS navigation in your pocket — plus premium bathymetry contours. Built for anglers who'd rather spend money on bait than chart subscriptions.

Everything you need on the water
Professional chartplotter features without the professional price tag.
NOAA Charts
Official NOAA nautical charts with full detail — channel markers, depth soundings, hazards, and more.
Depth & Bathymetry
Bathymetry contour overlays with a species-targeting depth band, plus a FishHogs Depth chart mode with graduated depth shading — reveal structure, drop-offs, and the spots fish actually hold. Premium.
Markers & Catches
Save and organize your favorite spots with custom markers, and log every catch with species, size, and location.
GPS Navigation
Real-time position and heading overlay on the chart. Always know exactly where you are on the water.
Group Sharing
Share markers, catches, and live location with your crew — plus in-app group chat to coordinate on the water. Premium.
Tides & Conditions
Tide predictions with fishing windows, currents, and marine weather for your location — so you know when to go.
Fish ID Guide
An SE Alaska fish ID guide with 64 species — rockfish, salmon, halibut & flatfish — with photos to identify your catch.
Reference Tools
A Tackle Box of on-the-water references — marine radio channels, fishing regulations, and a halibut weight calculator.

Why FishHogs?
We think anglers deserve better than a $100/year chart subscription.
