Well, that was an interesting day. But only if you find lightmeters interesting.
I asked my friends on Facebook if any of them had a lightmeter, and one of them is posting me a Sverdlovsk-4. I've had one in the past, and it was excellent. Incident, and a sort of spot meter with a little viewfinder.
I then went through all (two) of the digital compacts in my house. I found the old Minolta Z10 remembers that you selected spot metering between power cycles, but my Canon A720is doesn't. The Minolta reads a bit lower than I would expect it to though.
Re: the lightmeter app, I don't have a smartphone for everyday use. I try not to be too contactable when I am away from work.
