I’ve often wondered what the world would be like if a person could read the mind of every member of the opposite sex they encountered during the day. You’d know which ones thought you were cute, which ones would love to go to bed with you, etc. And without a moral compass, we’ be a rutting nightmare.
These apps kind of simulate that. Its not good.
Or it turns out you can just ask. Most “successful” dater I ever knew basically asked every girl in high school out, most turned him down, but even if you only have a hit rate of 5% spread across the entire female student body he got a lot of action.
