SEAiq vs Qastor Utilisation & Stats

SEAiq is a full-featured marine navigation app. It is the only marine navigation app that allows you to load your own charts in a variety of standard formats, including: S-57, S-63, iENC, BSB, and KAP. It also includes the ability to automatically download charts from NOAA for the USA and download of raster charts based on satellite imagery. Other features include: * Waypoints * Routes * Tracks * Night color modes * Anchor alarm * Automatic download and display of weather (wind & isobar) * Chart measuring tools (EBL/VRM) * WiFi-based NMEA and AIS No purchase is required to use SEAiq to view charts. All features are enabled during a 7-day evaluation period. After that, many of the features require purchase of an in-app upgrade. Continued use of GPS running in the background can dramatically decrease battery life.
