Offline navigation with many map formats - BSB3 (*.kap), NV-digital (*.eap), Bitmaps with calibration file (format: map, gmi, kml, kal, cal, pwm), OSZ (zipped osm tile collection), mbtiles, sqlitedb, Mapsforge vector format and online maps

AFTrack is the navigation display for your GPS and brings the world of hiking, biking, sailing, geocaching and more to your phone. The program handles tracking with smart and fixed logging features. It sends reports online or via SMS. It receives SMS position messages and shows it as way points. It exports tracks and way points, uses maps online and offline and much more.


GPS and other input

  • different gps sources: internal gps, internal with NMEA, bluetooth gps direct, USB gps, online gps over Wifi/3G, NMEA file
  • read NMEA, GpsD json, Signal K json, gdl90 protocol
  • work as gps daemon (nmea or json, port 2947 only)
  • share position (replaces standard gps provider)
  • connection with AIS server (NMEA format)
  • altitude correction (automatic or manual) and Kalman filter
  • pressure usable for altitude (if available)
  • pressure start altitude editable
  • automatic correction over weather server (needs net connection)
  • compute current from COG and CTW
  • Mixed mode - read external NMEA but use internal position data
  • log all NMEA sentences or selected


  • collect track data
  • add photos to a track
  • show routes or tracks in up/down hill colors
  • export tracks to GPX, KML, OVL, IGC format and send or upload it
  • import route data - GPX, TCX or KML format
  • import, export way points - GPX or KML format
  • import areas from KML format
  • use a kml.txt format to send exports direct via bluetooth


  • design a route or an area on the map
  • design a route using BRouter offline data
  • design inland waterway routes using BRouter special offline data
  • design a route using wind information and polar data
  • define a route/area as nogo line/polygon
  • edit a route or an area on the map
  • merge some routes
  • copy way points to route
  • get new way point from bearing, map or position
  • add predefined way point collection to map
  • revers routes
  • Routing in a corridor
  • off road routing along the line


  • online maps - pool editable, tile or WMS based
  • offline maps - OSZ format build by MobileAtlasCreator
  • offline maps - SQLite formats mbtiles and sqlitedb build by MobileAtlasCreator and/or Maperitive
  • offline maps - BSB3 format for marine navigation
  • offline maps - NV digital for marine navigation
  • offline maps - mapsforge vector format - with extra xml layouts usable (V5)
  • offline maps - mph/mpr format
  • use offline maps from jpg, png or bmp files
  • use offline maps with calibration file map, gmi, kml, kal, cal, pwm, tfw or jpr format
  • make own calibration for a bitmap
  • seamless maps display when using OSZ or SQLite tile container
  • map selector to have quick access to available offline maps
  • map scan for a defined folder and sub folder
  • map overlays - e.g. OpenSeaMap, online pool editable
  • map offline overlays - in mbtiles 'overlay' format


  • wind indicator for the map or position center
  • display depth - if available
  • display AIS information - if available
  • display ADS-B (air plane) information - if available
  • vario display
  • vario sound
  • alarm on reached POIs
  • set anchor alarm for the current position
  • set anchor alarm for a way point that receives positions from a gps tracker
  • save and restore settings
  • send waypoint or anchor alarm to Android Wear


  • Online position sending for live tracking
  • Online receive way point positions from a GpsGate server
  • works as SMS provider (since Android KitKat)
  • short message position sending
  • short message position receiving
  • short message from GPS tracker TK102, TK102-2, TK102 clones, TK-Star, DNT, ELRO, GEODOG, Benefon ESC, Benefon Trackkeeper NT, WondeProud spt10, Tracker from, Wo-ist-Lilly or SmartcomGps
  • text storage for short messages e.g. for Xexun tracker
  • set position from short message
  • send sms note to other AFTrack instance and get position back
  • collect short messages to a track, single and multi-tracking
  • convert received way point history to track
  • getting way point positions from a GpsGate server



To fix space or special interests AFTrack works with plugins. This small apps are not visible in the Android launcher - only in AFTrack or the system settings /apps

  • SailTimer™ - uses the SailTimer Wind Instrument™ to work with wind data and uses the SailTimer™ wind cloud
  • Calypso Ultrasonic - uses the Calypso Ultrasonic Wind Instrument to work with wind data
  • MTK - download track direct into AFTrack from MTK gps chip
  • BlueSkyVario - get pressure values from BlueSysVario sensor hardware
  • SensBox Vario - using altitude and/or gps data, see at Flytec
  • OpenUV - get the UV index data from - needs net connection.
  • Grib - download and view GRIB dataon map (version 1 and 2)
  • SMS - the SMS functions need a plugin (since 1.10.2, Google removed SMS features)
