'Slow dating' is the trend of getting to know one person at a time, going on a few dates before sleeping together, and not constantly swiping for someone new on apps. A backlash against the rapid pace of swipe-dating apps like Tinder. Some dating apps (Hinge, Thursday) market themselves around it. If your teen is into slow dating, they are taking a more deliberate approach. Healthy and emotionally mature; nothing concerning.
