Vespucci app can be used to do it directly on phone.
Vespucci vs StreetComplete are quite interesting, in many aspects they are complete opposites.

I try to maintain all restaurants etc in Denmark by comparing OSM POIs to public health inspection reports. see: https://digitalfrihed.dk/restaurants/all.html
So today there are 243 restaurants, cafes and fast food places in OSM that do not have a valid inspection report (the pink ones on my map). I think that many are just closed temporarily because of Covid and therefore have not been inspected and the inspection report just timed out. Probably some that have an inspection report will never open again, but I will soon find out. Many of them are cafeterias for employees in larger companies and will likely open again.
Many restaurants are open for takeaway, also many that did not do takeaway before the lockdown.
I have lately been doing speedlimits, mostly from Mapillary. But I have also done some surveying on bicycle.
