## What is Nearest Light?

Nearest Light is a informational aid for U.S. waters that shows your location and details on all surrounding aids to navigation (buoys, lights, etc) within your Area of Interest.  The app downloads the weekly U.S. Coast Guard Light List for your district, and then shows the aids within your Area of Interest and their details.  Any applicable Local Notice for Mariners information is also shown with the light data.  Refer to the User Manual (url in Settings) for additional information.  

Districts: D1, D5, D7, D8, D8WR, D9, D11, D13, D14, D17

### 5/5 — Great App

*2025-10-10*

Hello, thanks for creating this app, very useful interface. But how do we change the Area Of Interest? It is only showing the aids immediately near me, I'd like to look at other waterways within the same district.

### 1/5 — APP IS DOWN

*2021-09-29*

This app is great but it’s been down since September 201

### 5/5 — USCG ANT VENICE

*2021-06-17*

First things first…great app! I’ve used it for the last year to assist in lost storm surveys and making sure the LNM was running with the app. It’s worked every time for a year until 2 weeks ago!! Please get it working!! It loads last LNM and then closes on its own. The USCG ANT NOLA crew uses it too and also experiencing this issue. Seriously we need this app

### 1/5 — Does not function

*2021-02-05*

Unable to pull up local ATON, unable to search by LLNR

### 5/5 — Very cool - USPS Coop-Charting program user

*2020-03-06*

This app could be extremely useful with the Coop-Charting program users... I can imagine enhancing this to be able take pics from it and attach directly to ATON verification report and then auto  output... any plans along this line?

### 5/5 — Great navigational aid

*2020-01-06*

I perform aids to navigation verifications for the Coast Guard Auxiliary. This app is priceless in assisting in that effort. Boaters can use it to obtain the information necessary to notify the Coast Guard of issues with these aids.
