Read full description

AngelNav is a new app for iOS developed in collaboration with Tom Cunliffe. Primarily it is a full chart plotter currently favouring raster charts, but it has many additional features including the ability to carry out traditional navigation directly on the screen. The capacity to generate classical chart work is vitally important in the event of a GPS failure, but hitherto has required pencil, plotters, and paper charts. AngelNav allows traditional techniques to be carried out using an iPad or iPhone screen instead of a paper chart. An estimated position can be plotted, position lines drawn from sighted bearings and fixes recorded. Course-to-steer diagrams are readily constructed. AngelNav can read most types of raster chart including the UKHO subscription charts, as well as KAP/BSB files and GeoTIFF files. It can easily create georeferenced satellite charts for offline use. AngelNav can take GNSS navigation data from a variety of sources, including the device's stand-alone GPS, the boat's NMEA over WiFi, and SignalK. It will also display AIS information if available. Annual subscriptions are available as in-app purchases for UKHO, SHOM, and Imray charts covering the whole of the UK, France, Spain, the Mediterranean and the Caribbean. These are divided into folios so that you can subscribe only to the charts that you need. The app is free to use in its basic form, with additional functions and charts available as in-app purchases. This allows a user to fully evaluate the app without charge, and then to purchase the features and charts required.
