I usually don't use any tracking applications; there is a unique platform where I enter the tracking number of not my product and get information about it. As for me, it is the most convenient option because you are not faced with a lot of unnecessary advertising and other things that can distract you. After all, you enter a tracking number into the platform https://www.sendungsverfolgungpost.de/de/ , and you get immediate information about the whereabouts of your parcel. If you notice anything amiss or that your package is taking a long time at any location, you can immediately contact the seller.
