The Quotas app allows panellists of our measurements to enter their data in a more convenient way. Advantages of the App compared to the data entry via our website are: • You do not have to look for the correct letter number in your list anymore. Just easily scan the bar code and the corresponding letter will open up. • If you use QR code scanner you do not have to enter the corresponding identification code. • Fast availability of all test item specific questions adjusted to your smartphone. The Quotas-App is currently available for the following measurements: • PostNord Danmark measurement • Post Norge measurement • UPU GMS measurement • Deutsche Post AG Brieflaufzeitenstudie We are continuously working on further upgrades to make the App available for more measurements and to extend its functionality. In case you are interested to join our measurements kindly go to www.brieflaufzeiten.de (participation in measurements within Germany) or www.world-mail-panel.com (participation in international measurements).
