The track recorder

The track recorder allows you to record GPS locations at regular intervals along your path, so you can get detailed statistics and graphics of your hikes.

It runs in a light background service called the “AlpineQuest agent”, and can track your locations even if the main application is completely closed to save as much battery as possible. If you use any memory cleaning application, be sure to exclude the agent from being automatically killed.

All recorded tracks can be stored in the application or exported in various formats to be displayed in external softwares like Google Earth.

How to start recording a track?

To start the track recorder:

  • Tap on the Positioning menu icon and on the Track recorder toggle .

Alternatively, you can:

  • Tap on the Positioning menu icon;
  • Tap on Track recorder to display the track recorder panel;
  • Tap on the Track recorder toggle at the left of the title bar.

This second method allows you to change the track recorder settings before starting it, by tapping on the Settings icon.

At any time you can close the track recorder panel by tapping on the Close icon, or even completely close the application, the track recorder will keep on recording locations in the background.


How to get information on the current track?

When the track recorder is started, an information box is displayed giving the total length and time recorded so far. The positioning menu button turns blue, and the recorded track is displayed in blue on the map.

At any time, you can tap on the recorded track to display the track recorder popup menu.

  • Tap on Track recorder to display the track recorder panel ;
  • Tap on track icon to get detailed information and statistics on the whole track;
  • Tap on location icon to get information on the selected location.

The Track recorder panel gives you the main statistics on your track (total length, total time, moving speed, moving time, elevation gain and loss), together with the speed and elevation profiles.

Tap on Details to get detailed statistics. In the information window, you can tap on More to get even more statistics.

More information on statistics is available here.


How to add waypoints and pictures?

While recording a track, you can add waypoints and pictures to it.

To add a waypoint or a picture at your current location:

  • Tap on the screen center icon and on Track recorder to display the track recorder side panel;
  • Tap on Waypoint to add a waypoint, or on Picture to add a picture.

The application calls the default device Camera application to take pictures. If the default Camera application is not compatible, you won't be able to take pictures as explained here. The alternative solution is to take regular pictures with your Camera application, and add them later using waypoints linked to pictures taken from your gallery.

To add a waypoint or a picture at any other location:

  • Move the screen center icon over the location you want to add the waypoint or picture on, and tap on it;
  • Tap on the Add waypoint icon to add a waypoint, or on the Add picture icon to add a picture.

Track waypoints are exported with the track when choosing the GPX, KML or KMZ formats. Pictures are only exported when choosing the KMZ format. The resulting file size may be large depending on the number of pictures.


How to pause or stop the record?

At any time, you can pause the track recorder by tapping on the location tracker toggle . The background service will be completely stopped, but the recorded track will still be displayed on the map. For example, you can pause the track recorder during the night of a two days hike.

You don't have to pause the track recorder during small breaks, the application will automatically detect that you're not moving and will take this into account when computing statistics.

To resume the record, just tap on the track recorder toggle again.

If you've reach the end of your track, tap on Save & Stop to stop the track recorder. If you want, you can type a name for your track and/or add additional information like a description or a display color by tapping on More… . Tap on Ok to save the track and remove it from the map.

You track will be displayed in the Last recorded track section, from where you can:

  • Resume it by tapping on Resume ;
  • Display details, statistics and graphics by tapping on Details ;
  • Display or hide the last recorded track by tapping on its name .


How to list recorded tracks?

At any time you can list all previously recorded tracks:

  • Tap on the Landmarks menu icon and on Explore landmarks ;
  • Tap on the Recorded tracks folder to list all recorded tracks ;


How to export recorded tracks?

You can export your recorded tracks in various formats to use them in an external applications.

  • If the track you want to export is the last recorded one, tap on the track menu icon to display the actions menu;
  • If the track is not the last recorded one, list the previously recorded tracks by tapping on Recorded tracks and long-press the track to export (or tap on its icon ) to display the actions menu;
  • Choose Export as… in the track actions menu.

In the list of available export formats, choose the one that best fits the external application you want to use, for example GPX which offers a very good compatibility.

Once the track has been exported, the full path of the exported file is displayed.

  • Tap on Share to share the file (send it as email, upload it on Dropbox, etc.);
  • Tap on Open to open the file with a compatible application installed on your device (available choices depend on the applications installed on your device);
  • Tap on Ok to close the dialog.

Be careful when trying to access the exported file from a computer using an USB cable, Android takes time to update the file list of your device, and newly created ones may not be immediately visible.


The track recorder settings


  • The “Location source let you choose which locations to record. Most people will choose “Outdoor GPS”, but you can change it to “External locations” if you have an external bluetooth GPS you want to use;

Some location sources can be disabled from the device settings. Tap on “Settings to open the device location settings.

  • The “Update frequency allows you to choose how fast the locations have to be recorded. For runners, a precise tracking like “(/2 seconds)” is recommend, whereas hikers should prefer a medium one like “(/10 seconds)”, since a fast tracking will use more battery.
  • Check “Warn me if the GPS signal is lost or too weak if you want to be notified (by a notification sound) if the GPS signal is lost (recommended);
  • Check “Skip locations if I'm not moving if you don't want to record multiple locations at the same place when you're not moving (recommended);
  • If your device has a built-in pressure sensor, you can check the “Record pressure values to record more precise barometric elevations option. The application will compute elevation values based on the air pressure, in addition to the common GPS elevations. These barometric altitudes are much more accurate and reactive, and can be computed precisely even if the GPS signal is very poor.

The pressure values are automatically calibrated by the application using GPS locations.

Problems with the track recorder

Track not recorded when the screen is turned off or when another application is displayed
Lot of recent devices come with a security and battery management application that doesn't allow an application to use the GPS when it's not displayed. Be sure to disable this behavior or grant the permission to use the GPS while in background. Here are some examples:

For Huawei devices (1): Settings > Power usage firewall > Close excessively power-intensive apps
For Huawei devices (2): Settings > Lock screen cleanup > be sure the application is not selected
For Huawei devices (3): Settings > Apps > Settings (bottom of the page) > Special access > Ignore optimisations > Change to all apps
For Mi/Vivo devices: Settings > Permissions > Autostart
For other devices: Settings > Battery > Battery Optimization

For some devices (like Huawei Mate 10), a system update can also fix this problem.

Track incompletely recorded
Starting with Android 6, when the system thinks the device is not used it can automatically halt running applications for some time to reduce battery usage. During this time (called “doze” mode), the application is no more able to record the track, leading to skipped parts of the path. Hopefully, you can prevent this behavior by disabling the doze mode for the application from your system's battery optimisation settings:

Settings > Battery > Battery Optimization

Under “All apps”, select “AlpineQuest” and choose “Don't optimize”. More information is available here.

The track recorder service stops
In addition of being closed by the system as seen before, some “device/memory cleaner/booster” applications automatically kill background processes. If you use such applications, be sure to add the track recorder service in the exclude list of your cleaning application so it doesn't get killed.

Loss of the GPS signal
A common issue when recording a track is the loss of the GPS signal, leading to a missing part in the recorded track (seen as a straight line longer than usual). It usually happens because the device doesn't have a good enough access to the sky, for example when the device is placed in a deep pocket or in a bag. The GPS signal emitted by GPS satellites is weak and get easily lost when going through any material. If you have checked “Warn me if the GPS signal is lost or too weak option, the application will play a song when this happens.

Device gets hot
Tracking a path requires frequent GPS location updates and some devices (mainly old or low-cost ones, but not always) doesn't support the GPS being turned on for long hours. Common symptoms in this case can be:

  • The device becomes more hot than usual;
  • The GPS doesn't report satellites anymore for some time, the location fix is lost, leading to a missing track part;
  • The track recorder service is simply closed, the record is stopped.

If you encounter one of these symptoms, you can try to:

  • Reduce the tracking frequency, a location per 10 seconds is a recommended setting for hours long tracks;
  • Use an economy tracking frequency (starting at 1 location / 20 seconds), in which the GPS is completely turned off between update. Be sure to leave your device in view of the sky so the GPS can quickly retrieve a location for each update;
  • Turn off the use of barometric elevations to leave the pressure sensor turned off (this one can also be the source of problems when continuously used for long time).
