Plenty of such on Taobao. I guess you can find them on aliexpress

Oh god in Germany 100Mbps/45Mbps costs 40€/month! Electricity is like 0.5€/kWh! There isn’t any charity shop! I envy you!

The wife (or whoever does the cooking and shopping) is actually so organized that he/she uses an app to plan everything?! My wife wouldn’t even have her windows desktop tidy.

Sorry off topic. I haven’t found one that’s impactful for the whole family. The most important might be the photo backup app (currently synology photos, might be immich later on), but I just configure it for my wife so that she forgets about it and the backup runs silently in the background. I recently retired an old synology nas to my parents and configured it for them too.
