Use trackr! to let people know where you are and where you have been. All you need is the Internet, a GPS receiver and your mobile phone (or a mobile phone with an internal GPS receiver). Download the application to your mobile phone, create a friendslist and let your friends know where you are!

  1. share your current location and track history with your friends
  2. see on your mobile phone or on the trackr! website where your friends are
  3. view what tracks you or your friends have traveled: distance, average speed, etc.
  4. receive a warning when someone enters and/or leaves a certain area (geo-fencing)
  5. include a map with your current position on your own website/blog
  6. use the Quick Access Code to immediately show others where you are at that moment
  7. trackr! is FREE for personal use

About trackr!

trackr! uses GPS and Google Maps. It consists of two parts: the website trackr! and the software on your mobile phone.

What do I need?
To use trackr! you need a mobile phone with a data plan (for example GPRS or UMTS). You also need a GPS receiver (as a seperate device or builtin).

trackr! currently works on the following mobile phone types:

  1. Windows Mobile 5 and 6 (PocketPC and Smartphone).
  2. phones with support for MIDP2.0 ( E50, N73, N95, etc.).

Getting started
First download the application for your mobile phone (see the step-by-step description). After installing and starting the application on your mobile phone your friends (approved by you earlier) will be able to see where you are on the website. Of course only as long as you want them to see you. Your location is determined using GPS.

Your friends will be able to see where you are if they are logged in to the website. You can also give someone a quick access code. If they enter the quick access code on the trackr! homepage, they can immediately see your position without creating an account or logging in.

Obviously you can also see where your friends are if they use trackr! as well.

Of course you are always in control and you can switch off the application whenever you want to prevent others from tracking you.

Are there any costs involved?
trackr! is FREE for personal use. The mobile data connection provider might bill you for data traffic.

The version of trackr! requires:

  1. The mobile phone has to support at least MIDP 2.0 and CLDC 1.1

Many current mobile phones e.g. , Motorola, Siemens, Sony Erricsson, etc support midlets using MIDP 2.0.

The trackr! client is currently still in development and regularly improved. We still would like to give you the opportunity to try trackr! in this early stage. So far users have reported success with the following devices:

  1. E50
  2. N73
  3. N80
  4. N95

Changes
version 0.1.9 - fixes ‘out of memory’ issue found on the N95, which crashed the application after a while.


Instructions
Installation
Install trackr! using the Application Installer (part of the PC Suite).

Starting
After installation, you can find trackr! using ‘Menu’ -> ‘Installations’ or ‘Menu’ -> ‘Applications’. After starting trackr! for the first time you will be asked to enter your username and password. These are equal to the username and password used to create an account on the trackr! website. You can also configure the interval used to send data to the server in the ‘Settings’ menu. As soon as the main screen opens, you can start a session using the ‘Start Session’ option in the menu.

Functionality
The current version only supports a part of the functionality of the Windows Mobile Version. Important things to know:

  1. Starting from version 0.1.2 it is possible to use the ‘offline’ mode as well (as opposed to ‘live’ mode). Live mode means that each time after a configurable number of seconds positioning information is sent to the server. This allows other to follow you in a near realtime way. In ‘offline’ mode data will not be sent directly (e.g. using GPRS) but stored on the mobile phone. This data can be submitted lateron.

    Please note: when starting a live session, data will be visible on the website in the ‘My live position’, ‘Position of friends’ and ‘trackr! on your site’ sections. For tracks to show up in the ‘Saved tracks’ section you have to first send these from the mobile phone using the ‘Saved Tracks’ menu item (even when using the live mode!).

  2. The application is not ’signed’ yet. This causes a warning message to show up on your mobile phone during installation. Also, after starting the first session, two warnings will appear. One is asking permission to setup an (GPRS/UMTS) Internet connection and one for access to GPS data.
  3. You can exit the application using the red ‘End Call’ button on your mobile phone.
  4. Using the ‘menu’ button you can return to the mobile phone menu while trackr! remains running in the background (and will still process and send positioning data). You can continue to use your mobile phone and start and receive calls. To return to the trackr! application, push the ‘menu’ button for a few seconds. A list of background applications will appear. Choose the trackr! icon to return to trackr!.
