Additional information about the charts and data provided with this app:
NOAA RNC® charts are full-color, geo-referenced, digital images of NOAA paper nautical charts.

RNCs can be used with global positioning system (GPS) enabled electronic chart systems or other “chart plotter” display systems to provide real-time vessel positioning.

NOAA RNCs comply with the International Hydrographic Organization RNC Product Specification.

RNCs are approved for use by IMO ECDIS mandated vessels only if adequate ENC data is not available. Since complete ENC coverage is available in all U.S. waters, vessels required to use ECDIS may not navigate with NOAA RNCs.

NOAA RNCs DO NOT meet USCG chart carriage requirements for commercial vessels.

NOAA RNCs may be downloaded free from the NOAA chart locator or the NOAA nautical chart catalog.
----------

Electronic Navigational Charts (ENC) are vector data sets that support all types of marine navigation. Originally designed for large commercial vessels using a sophisticated navigational computer called an Electronic Chart Display and Information System (ECDIS), ENCs are now also being used on simpler electronic chart systems and “chart plotters” on many types of ships and by recreational boaters. NOAA ENCs help provide real-time ship positioning, as well as collision and grounding avoidance.

NOAA ENCs comply with the International Hydrographic Organization ENC Product Specification. ENCs are produced around the world by many different countries’ national hydrographic or charting agencies. NOAA maintains more than 1,000 NOAA ENC® datasets over U.S. coastal waters and the Great Lakes. The U.S. Army Corps of Engineers produces a similar product, called Inland ENC (IENC) for many U.S. rivers.

### 1/5 — Not working today

*2025-01-28*

Not working with my iPhone ( 18.2.1 ) at all.  Try to access a chart and it just goes black .   I could find no help in the app, nor from the grander universe

### 1/5 — Another Don’t do it

*2024-06-06*

I’ve been over this app 1000 times and I still can’t get it to download anything other than a blank page on the chart I select. I clicked download, it says downloaded, the file appears nowhere on my iPad and when I try to open it I get the blank page that downloaded. contact for the developer is nonexistent.

### 1/5 — Crashes every time

*2023-12-29*

Crashes every time I try to download a chart.  How do I get my money back?

### 1/5 — Could be good  if it could do the 1 thing it’s supposed to do

*2023-10-17*

Paid for this app. Seemed simple and uses NOAA charts that are freely available. Trying to download a map causes the app to crash. Can’t even do the one thing it’s designed to do. 
Restarted the phone and it continues. I hope there’s a fix soon. Not a great start.

I love how this is democratizing the charting space and away from big corporations that you need to pay over 50 or 100 to get a limited sets of maps. Keep up the good work.

**Developer response:** Thank you for the positive review!
