How much mobile data does this app use? Can I pre-download assets for my region?

[Swarkin]

I'm very limited by data (less than a GB) and would like to know whether this app has some low-data mode or even fully-offline mode while I'm outside?

You can turn off automatic uploads in the app settings and download the data manually for a specific region via the ≡ button (zoom level must be high enough, though, so you might have to do this multiple times). Then you can use the app completely offline.

Is it possible to download data for my entire city? Scrolling around and pressing download is a bit annoying

Is it possible to download data for my entire city?

via manual downloads

though typically just small part of city will provide quests for multihour walk

Scrolling around and pressing download is a bit annoying

you can zoom out just a bit before download is no longer possible (note that weaker devices + dense area can result in really long processing)

I'm very limited by data (less than a GB)

Note that app will refetch data if it is old. But it will work fine in offline mode if data was preloaded

(few years ago I was in such situation and SC worked fine, ot should still work)

You can turn off automatic uploads in the app settings

Remember to make manual uploads in such case!

Yes, but not at once; only with scrolling around and pressing download 😉

is a bit annoying

Yes, but the download area is limited to not overload the server and the phone which needs to process all the data.

There is a feature request to download along a GPX track (#473, #1757) that would mitigate that, and also a (abandoned?) work-in-progress PR (#5369). It sequentially downloads multiple areas along the track.

Thanks for the info all!

Relatedly, SCEE (StreetComplete "Expert Edition" fork) does already implement downloads along the GPX tracks. It also allows to disable automatic downloads (in case you might prefer that to completely disabling your mobile data for all apps)

I did some experiments with Street complete. If you pre-download the data it uses very little when you are walking around. See the last post get #3556
