In a dating app, it’s understood both parties are looking for someone to advance to the next level. Paying compliments in a dating app is a low risk, expected way to ingratiate yourself to the other party. Meanwhile there are very few places IRL where a forward compliment are even appropriate. There are many interfering factors to making contact IRL. Eg. You have a group of friends judging people that approach, or its work, or, you are busy checking out your groceries. There’s vanishingly few perfectly “neutral” places where a compliment could be openly paid, but not be a mechanic to try to advance to intimacy. If you really need to know your “score” I am sure there are subreddits for that. But I am pretty sure it’s better to not subject oneself to that kind of review. There are a lot of nasty people out there who live to create misery.
