SEAiq USA VPP app for iPhone and iPad

SEAiq USA VPP is a full-featured marine navigation app. It automatically downloads all charts (both vector and raster) from NOAA and the US Army Corps of Engineers for regions of USA you select.

[IMPORTANT: you can try all the features in SEAiq USA VPP by downloading our other app, SEAiq USA IAP, which has a 7-day evaluation period.]

Other features include:
* Waypoints
* Routes
* Tracks
* Night color modes
* Anchor alarm
* Automatic download and display of weather (wind & isobar)
* Active Captain Interactive Cruising Guidebook
* Chart measuring tools (EBL/VRM)
* WiFi-based NMEA and AIS
* Raster charts
* Vector charts

Continued use of GPS running in the background can dramatically decrease battery life.
