Skippers Log vs AngelNav

Skippers Log is your digital logbook for your yacht. Everything you can do in a good old fashioned paper logbook you can do here: - Create multiple trips for multiple ships - Record daily navigational data and weather observations - Include navigational live data from a wireless NMEA server - Automatic log entries based on the specifications you make (course change, wind change, ...) - Plot your trip on Apple map or Navionics map (active Navionics subscription required) - Print your trip with maps as a PDF - Create crew lists and print them - AIS targets shown on map (data from AIS receiver required) - Synchronize between you devices through iCloud - Display various data fields from NMEA data as overlay on your map - Fuel, water, cooking gas and outboard fuel consumption can be recorded - Take and add pictures to any day in the logbook (Premium version only) - Automatic geotag your position like e.g. "1.6 nm NW of Cape Finisterre" - Automatic download GMDSS and DWD weather forecasts (Euriope only, premium only) - Handling daily checklist (premium only) The free version of this app is limited to 1 ship, 1 trip and 40 manual log entries. Enough for a one or two week charter trip. No NMEA data are processed in the free app. In app purchase for the premium version and a 14-day free trial of the premium version. Please note, that the app will principally run on WiFi only iPads, but it is quite limited on these devices. Even if you use NMEA as your location source, automatic logging and track recording will likely reliably only happen while the app is in the foreground. You can still do manual entries, of course. To unleash the full potential you need a device with a gps receiver. Icons by Icons8

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.
