FishHogs

FishHogs is a free marine chartplotter for anglers fishing US coastal waters and the Great Lakes. View official NOAA nautical charts with bathymetry contour overlays, track your GPS position and heading, and mark your favorite fishing spots — all from one simple app.

NOAA NAUTICAL CHARTS
Access official NOAA electronic navigational charts (ENC) rendered as high-quality vector tiles. See channel markers, depth contours, hazards, and aids to navigation. Charts load fast and render cleanly at any zoom level.

BATHYMETRY CONTOURS
Toggle a bathymetry contour overlay to visualize underwater terrain. Find drop-offs, ledges, and structure that hold fish. Bathymetry data is sourced and served separately from NOAA charts for maximum detail.

GPS POSITION & HEADING
See your real-time position and heading on the chart. FishHogs uses your device GPS — no external hardware required. Works anywhere you have satellite signal, even without cell service.

MARKERS
Drop markers on fishing spots, structure, hazards, or any point of interest. Edit marker names and details, or delete markers you no longer need. Markers persist locally on your device.

LAYER CONTROL
Toggle NOAA charts and bathymetry contours on or off independently. Customize your view for the task at hand — full chart detail for navigation, contours only for scouting, or both for the complete picture.

USER ACCOUNTS
Sign in with Google or Apple to create a free FishHogs account. Accounts are the foundation for premium features as they become available. All chart and GPS features remain free without an account.

Built by anglers who got tired of paying for chart subscriptions. FishHogs uses free NOAA data so you get official nautical charts without the monthly fee.

IMPORTANT NOTICE
FishHogs is intended as a fishing and recreational reference tool. Chart data is sourced from NOAA and is provided for general reference only. This app is not a substitute for official NOAA nautical charts, Coast Guard Light Lists, or Notice to Mariners publications, and must not be used as the sole means of navigation.
