CIRCLE WITH A DOT

@argentum @Kishi @mattblaze @jernej__s @malwarejake don't make the review to bad or hard. Give the app half the stars or points or whatever and note the review function brought you here. After that mention the usual problems of, e.g. package pickup boxes with bluetooth and their apps ...

@Asterix_Archiv also Goscinny bei Tolkien? Tolkien wiederum hat sich am Motiv der Einherjer aus der Edda oder der wilden Jagd bedient.

@bagder would guess SQLite or libz. they are used a lot, and are also present in devices without network connection

@Larvitz sure - for me would the dead phone break more processes, e.g. calling or texting updates for an appointment - thus phone must not run out of power.
Not sure if it's already on your list: https://bahn.bingo/, it's also a great starter for smalltalk, when one has not managed to catch a single seat and has to interact with fellow travelers

@Larvitz I would add the recommendation - screenshots of the QR Codes of any card that might be controlled - Apps may stop working because of no network connection and the urgency to re-download something when opening the control view ... in my experience DB Navigator is happy to fail, especially when the ticket is booked with a Bahncard.

Instead of printing I add the calendar entries for the trip to my calendar and attach the PDFs.

but I also have a powerbank for emergencies in my bag.
