In Thailand, one popular social networking app that is often used to make new friends is called "Tinder." While Tinder is primarily known as a dating app, it is also used by many people in Thailand to meet new friends and expand their social circles. Users can set their preferences to look for either potential romantic partners or simply new friends.
Additionally, other general social networking apps like Facebook and Instagram are widely used in Thailand, and you can also use them to connect with people and make new friends. Facebook groups and events, in particular, can be helpful in finding like-minded individuals and social gatherings in your area.
As with any social networking platform, it's essential to exercise caution and be mindful of privacy and safety when interacting with new people online. Always meet in public places and inform someone you trust about your plans if you decide to meet someone you've connected with on any social networking app.
