I find myself checking out pretty often and just making myself feel bad about the state of the world, or killing half an hour on stupid games that I could 100% live without. This is probably pretty common, and I’m wondering what other people have found as a way to do more productive things with their phones in the downtime.
I make GPX traces for OpenStreetMap. I also make annotations and even small edits for the same project. Listen to music and YouTube videos (don’t really watch a lot), check my messaging apps, etc. I actually try a lot of stuff from Fdroid.
