Added an old phone with offline Wikipedia and maps to my 3 days survival box

As a small follow-up to my 3-day survival box post, I had some extra time this week and finally prepped an old phone I had lying around. I loaded it with offline Wikipedia using Kiwix, which turned out to be surprisingly easy. It has a built-in option to download the full Wikipedia or just specific sections, so in a few minutes (took few hours to fully download) I suddenly had a full offline encyclopaedia in my “pocket”.

I also added an offline map app and downloaded the regions around where I live, where I work and the surrounding countries. The phone has no SIM and no accounts, so it is basically just a tiny library and map device now. Since I was not using it anyway this feels like a nice little upgrade to my kit without spending anything.

Anyone else doing this kind of digital prepping with old phones or tablets? What apps or files do you consider must-haves for offline use? I’m also thinking about adding a movie or series to it to keep the kids occupied for example.
