Tinder could be useful. It all depends on what you want out of the dates.
There are apps that the locals refer to as 約炮神器 (hookup tool), and other apps that focus on people looking for serious relationships.
Usually, guys would have to pay for a subscription for those serious dating ups, and they tend to try to filter out escorts and other fake accounts. People still manage to fool the system, but those accounts would have their Line IDs written on their photos, so it’s super obvious.
