This app isn't just a meme, it can really help you get to know people in this overly-sensitive world.
Don't you dare call someone you like?
Afraid of hurting their feelings?
Not good at reading body language?
Want to get attention?
With this app, you simply walk up to your target and ask them to rate you like a dating app. If they want to communicate with you, they swipe right, if they had rather you leave them alone, they swipe left.
It's a cheap and simple app, nothing more than the pictures suggest, but it can be useful if you don't want to hurt the other person's feelings.
