In order to help you get started with the DLR MovingLab, we have provided a few introductory videos here: simply follow this link or visit us on YouTube.

Firstly, you will need a mobile telephone with an android operating system (at least version 4.4) or iOS operating system (at least version 9) as well as a mobile phone contract with data volume.

When the DLR MovingLab app is first started, a hardware test takes place and provides a corresponding report.
Please contact us if your mobile phone does not fulfil the requirements.

If this is the case, please get in touch with us as quickly as possible.

Use of the DLR MovingLab app is completely free of charge and free of advertising.

You can find the DLR MovingLab app in the Google PlayStore or in Apple’s AppStore.

For accounts with an e-mail address, a function is available in the login view to reset the password in both the app as well as the web portal.
If you do not use an e-mail address to log in, please contact us. Use the contact information in the Quick Guide for this.

The app uses approx. 30 MB of memory on your device.

Typical use requires approx. 2.5 MB of data volume per day.

In sleep mode, our test devices with enabled tracking used up about 10% of the battery per hour. We recommend that the mobile phone is charged at night so that you can start the day with a full battery.

There are currently display problems if the app is being used with enabled dark mode. Disable dark mode on your smartphone and restart the app. If text and entries are still not displayed, please contact us directly. We are working on further improving the app and ensuring compatibility with dark mode in future.

Yes, all other mobile phone functions can still be used. However, the use of additional functions uses up more battery. Tests with a wide range of mobile phones showed that, depending on the age and capacity of the battery, up to 18% of the battery could potentially be used per hour.

Studies have shown that standard cases for mobile phones disrupt the reception of location information (GPS) as well as transmission and reception performance. As the function of the app is significantly dependent on the quality of location data, certain accessories may lead to adverse effects on the functions of the app. Therefore, in case of problems, the app should be used without attachments and accessories.

Data are anonymised and stored in Germany in accordance with the Federal Data Protection Act (BDSG) and the EU General Data Protection Regulation (GDPR) and used solely for scientific purposes.
Further information on our privacy policy is available in the app as well as on the web portal.

The duration varies from one survey campaign to the next.

The more stages you correct, the better the system gets to know you and the more precise the results become. Therefore you should correct all wrongly recognised stages wherever possible.

In the app: enable tracking at the start of your trip (top right). A message simultaneously appears stating that your trip is being recorded. As soon as you have reached your destination, stop the tracking. After the software has processed the data from the sensors you will see your trip in the overview. Depending on the situation, this can take several minutes. If no trip appears, even after waiting for some time, please contact us directly.

Android: Ensure that you have given the app full access to the GPS sensors on your smartphone, also when the app is active in the background. In your smartphone’s location settings, select “High accuracy” and disable the energy saving mode if it was enabled.

iOS: Ensure that you have given the app full access to the GPS sensors on your smartphone.

GPS logger: ensure that the GPS logger is enabled and has enough power (see status LED). If the GPS logger signals that it is ready for use but is still not generating any trips, first switch off the GPS logger and then switch it on again after approx. 10 seconds. It may take several minutes for the recorded trips to be displayed. If no trip appears, even after waiting for some time, please contact us directly.

Please note that the recognition of trips and modes of transport are fundamentally dependent on the quality of the sensor data. In difficult situations (e.g. in a tunnel), the data may be incomplete or erroneous.

Correct wrongly recognised stages! Stages with the same mode of transport and trip purpose will be automatically combined.
In the case of a disproportionately high number of stages, you can report your trip in order to inform us of the problem.

We are currently working on a function which divides the stages into two or more.
In the case of a disproportionately low number of stages, you can report your trip in order to inform us of the problem.

If you forgot to enable tracking you have the option to manually enter the trip using the "+" in the app or using "Add trip" in the web portal.
Please note that manually entered trips are not divided into stages.

The LED’s colour and flash frequency provides information on the status of the GPS logger:

In the web portal, identify the last position the GPS logger was recognised at and try to find it there. If this is not successful, please contact us immediately.

The data are saved at DLR, but continue to remain connected with your account so that you will also be able to access them in the future. Users who are given the GPS logger after you will not be able to access any of your data.

The GPS logger records 2–3 days of data without being charged. To be on the safe side, it is best to charge it once a day.

Please fully charge the battery and try to switch the GPS logger on again. If this is not successful, please contact us immediately.

The GPS logger is not sealed against water.

Please note that deleting your account is permanent. As an alternative, you have the possibility of disabling your account. You can re-enable and use a disabled account again at any time. In addition, we are only able to continue using your survey data for our research in this way. If you are sure that you really wish to delete or disable your account, please send us an email stating which you desire with a short reason. If you request a deletion, we will delete your account and all the data connected to it within two working days.
