HarborAR is a supplemental, eyes-up marine navigation companion for iPhone.
It is not a navigation instrument, chartplotter, ECDIS or depth sounder, and it is not a substitute for official charts, onboard instruments, and prudent seamanship.
US coastal and inland waters where HarborAR has published a region. Published regions: Chesapeake, Ohio Louisville, South Florida, Tampa Bay. AR channel markers and tide predictions are currently available in the South Florida region.

Six views of the same voyage
Each surface explains a focused part of the route while keeping its limits visible.
Navigation HUD
Keep the next charted aid, bearing, distance, and route status in view during an active voyage.
Guidance depends on device location and the route you selected.
Charted depth
See charted depth shading and a shallow-water warning based on your vessel draft and safety margin.
Charted depth is not live depth, and conditions can differ from the chart.
AI First Mate
Ask a route question and receive an answer limited to the guidance values HarborAR has already computed; it explains, it does not steer.
The answer can be incomplete or inaccurate, so check it against official charts and onboard instruments.
Night mode
Night mode reduces interface brightness and shifts operational surfaces toward a restrained red appearance.
Display settings do not change the underlying guidance or shallow-water evaluation.
Made for the water
HarborAR has been field-tested on Biscayne Bay with recorded routes, device telemetry, and reviewed marker observations.
Field-testing supports iteration; it does not certify conditions, routes, or outcomes.
Field notes / Biscayne Bay
Built between shoreline and channel
Field sessions compare recorded location, heading, and marker observations with the app’s rendered guidance.
Those sessions find problems and guide revisions; the operator still verifies every voyage against current official information.
