Organic Maps is a fantastic alternative to Google maps, especially if you want to go biking or hiking. They use Openstreetmap.
For one, the DB Navigator app is a real multitool about most things public transport, even if you are not taking high-speed trains. You can use it instead of most local official apps.
Not Germany specific, but if you need an eSim for mobile phone service while you’re here visiting, I would recommend Airalo. Really good prices for a temporary SIM (e.g. $10 USD for 3GB) and no need to go through the hassle of registering and activating a SIM card.
I still hold on to my German sim, so that's not a problem. And unfortunately eSIMs are banned in China since you can just download any random one and bypass the great firewall, so our phones are restricted to physical ones :-/
Wife, huh? Congrats :)
Haha, thanks! And sorry for the late reply, somehow the comment notifications don't work properly here...
