Installed audio app
Catalogue, integrated maps and GPS can be useful when the setup is already finished.

Berlin audio field test
Will the format still work outside?
Move through four real moments. Change your preparation, battery and trip scope to see where an app, browser route or MP3 backup creates the least friction.
Current moment
Before leaving the hotel
This is the cheapest moment to install, sign in, download files and save the first stop. Any format can work if the preparation happens here.
Best move
Open the route once and save the offline files while the connection is stable.
Format under pressure
Scores describe this scene, not every audio product.
No-app browser route
Fast opening for one chosen route, with map links and a backup saved before the walk.
Scene fit0
Downloaded MP3 backup
The most dependable audio layer offline, but less useful for finding the next stop by itself.

What I would do
Prepare the browser route and save the backup.
For one Berlin walk, the browser is the quickest front door. The MP3 is the fallback if signal or battery changes later.
