I don't have that app on my smart phone (I don't have a smart phone).
The old "one man's trash is another's treasure" is apparently still true, but by the time I discard something I generally value it negatively (i.e. a nuisance). Either something I can't fix, or is not worth fixing. The wall oven was so old repair parts were not available, while the 50 years newer technology is so much nicer. ;D
Down here in the deep south the old school way to recycle unwanted household goods is to have a "tag sale". The family hosting a tag sale puts up flyers on telephone poles around the neighborhood with date and address of the "tag sale", usually on a saturday. The more aggressive shoppers will show up at dawn to cherry pick through the treasure. Sometimes a couple families get together to assemble a critical mass of junk to sell. The name "tag sale" comes from the practice of putting price tags on the old junk, piled out in the yard and on the driveway, while price haggling is probably common.
Generally if I am going to discard something of actual value I will try to give it to a neighbor. I gave one neighborhood kid an old treadmill I paid $3,000 for new, a few decades ago, since I can no longer run. I also gave away a still serviceable Schwinn air-dyne exercise bike ($700 new) I no longer use to a different neighbor (he doesn't use it either). There are collection bins for old clothes and I have donated my share of old clothes that I no longer wear. Just a couple weeks ago I wore a tie and jacket, for the first time this century (surprising a few people who never saw me wear one). The better tie I tried to wear that day had been chewed on by moths***. For some reason the moths only ate the red thread/yarn.
Right now I have a different neighbor trying to give me an old mattress and box spring he is discarding this month. It will surely get picked up by local scavengers. In fact years ago when I was cleaning nasty mold out of my house I replaced my bed, and discarded the old one. I was appalled that somebody picked it up... while it looked in pretty good shape (close inspection revealed small evidence of mold).
Within the last year a flea market has opened up in town, inside an empty building vacated by a lawn equipment company that moved out. I haven't been even a little interested to check out their fleas even though I drive by it on my bike route.

*** Imported brown rice can often have live moth eggs in it. I have learned that stashing the rice in the freezer for a week or two before using will kill the eggs. Took me a while to learn that trick but now I keep an extra bag of rice in the freezer. And swap out with fresh rice each time I buy more. No new moths for several years, but too late to save that tie.
PS: When I moved down south from CT back in the mid '80s I hired a dumpster to hold the accumulated crepitus I had accumulated (I am a pack rat). They didn't have a half sized dumpster to rent me so gave me a full size dumpster for the price of the half. I filled it up with junk, and had an overflow pile almost that large again sitting next to it, that they collected too. These days I try to be more disciplined about discarding stuff routinely.
