What is Real Time GPS Tracker?
- Real Time GPS Tracker is an application for android phones enabling you to share your current location on Google Maps. The application is absolutely
free and very easy to use.
Where can I get Real Time GPS Tracker?

How can I see my location?
- Launch the app on your phone and push the start-button. Choose username and password and wait until your phone receives
the GPS signal (you need clear view of the sky).
- Login to this website using the same username and password you have chosen in the previous step. You should see your location on Google Maps now.
How can other users see my location?
- The easiest way is to use the sharing function of the app. You can send a message to your friends. They just need to click the link in the message
to see your location on Google Maps. Optionally you can upload a photo which is used to show your location on the map.
Can I record tracks lasting several hours or even days?
The web portal always shows your latest track, comprising a maximum of 1000 location updates. Older location updates are deleted periodically.
you plan to record longer trips and you want to keep the complete track you will need the Track
Loading feature. As long as this feature is active the server won't delete any of your trackpoints. Moreover you can download all of them and you
can display tracks on the map even if they contain more than 1000 trackpoints. More information about Track Loading is available here.
Note: As soon as Track Loading expires the server will start again to delete your
trackpoints. If you want to keep them you have to download them before.
Can I start/stop the tracker via text messaging (SMS)?
Yes, if you have configured a keyword in the settings you can start and stop the tracker by sending a text message (SMS) to your phone. Please note
that the tracker will only start/stop if the text message contains a specific phrase which consists of two parts:
- The first part is the keyword configured in your settings. If your keyword is "track123" this part looks like this: rttpwd=trackme123
- The second part depends on the command to be executed:
- When starting the tracker, this part is "rttcmd=startservice"
- When stopping the tracker, this part is "rttcmd=stopservice"
Example: If you set your keyword to "track123" following text messages will be valid:
- To start the service, send "rttpwd=track123 rttcmd=startservice"
- To stop the service, send "rttpwd=track123 rttcmd=stopservice"
- To start GPS (if service is already running), send "rttpwd=track123 rttcmd=startgps"
- To stop GPS (and keep service running), send "rttpwd=track123 rttcmd=stopgps"
Please note that starting the tracker remotely doesn't necessarily mean that it will send the phone's current location. For example, if data
connection is switched off or if the phone is inside a building where no GPS signal is received, the tracker will not be able to send the track data.
Why do my tracks disappear sometimes?
- Real Time GPS Tracker displays the most recent track points on the map. If you stop moving all sent track points will refer to the same location and
the track will become shorter and shorter. As soon as you continue moving the track will grow again.
Are there more features?
You can send not only your location but also messages. The viewers in the portal can see your last sent message (if it's not too old). They can also
send messages to your phone.
Another feature is Track Loading which means you can view
your location data from the past. However, this is a non-free feature. If you are interested to test this feature 24 hours for free please contact me
via the forum on my homepage.
Is there a password recovery service available?
- Password recovery is only possible if you have entered your email address in the web portal settings. Please contact greenalp support to get receive
a new password.
Can I integrate the map into my own web site?
For now greenalp.com does allow to embed the map into external sites, so the answer is yes. However, there is no guarantee that this feature will be
available forever. More information...
