Handy GPS vs AngelNav

The perfect companion for your next outdoor adventure. Seek, find, record and return home with Handy GPS. This app is a real navigation tool designed for outdoors sports like hiking, bushwalking, mountain biking, kayaking and trail riding. It allows you to work in UTM or lat/lon coordinates. Features: * View your current location in UTM or Lat/Lon formats. * Record and/or manually enter waypoints in UTM, Lat/Lon, or MGRS. * Goto a waypoint, with optional audio proximity alarm and spoken directions. * Record a track log. * Show your current location, waypoints and tracklogs on a map. * Export waypoints and tracklogs to a KML file for viewing in Google Earth, or to a GPX file. * Export waypoints to a comma delimited (CSV) text file. * Import KML or GPX files and view in the app. * Email your current location to a friend. * Odometer to keep track of how far you've gone. * Magnetic compass. * Elevation profile. * Compute sun and moon rise and set times. * Supports both metric and US/imperial units. * Supports datums WGS84, GDA94, AGD66 and AGD84. (Use WGS84 for NAD83) * Allows entry of parameters for a custom datum (e.g. ED50, SAD69, OSGB36, GDA2020 etc), as well as supporting affine parameters for local grid systems. * Can display your location a normal grid ref, an MGRS grid ref (WGS84 datum only), or as a UK Ordinance Survey (OS) grid ref. * Can download offline map tiles for use where there is no cellular coverage. * Can import pre-prepared state or country-level base maps from a zip file. * Optional walk timer. * Email your current waypoints and tracklogs as a KML file. * Take photos from within the app to be stored with the current session. Disclaimer: Continued use of GPS running in the background can dramatically decrease battery life. To save battery power you can close the app from the task manager. The developer accepts no responsibility for you getting lost while using this app.

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.
