I can give you some general insights on the three apps you mentioned: Tinder, Bumble, and Boo.
Tinder: Tinder is primarily known as a dating app, but it has also been used for making friends. It allows users to swipe right to indicate interest in someone or left to pass. If both users swipe right on each other, they can start chatting. While some people have successfully made friends on Tinder, its primary focus remains on dating and casual relationships.
Bumble: Bumble is similar to Tinder but has a unique feature that differentiates it - it puts women in control. In heterosexual matches, only women can initiate the conversation after a mutual swipe right. Bumble also has a "BFF" mode, specifically designed for making friends. Users can switch to this mode and look for platonic connections rather than romantic ones.
Boo: "Boo" is a popular nickname for the app "MeetMe." MeetMe is a social networking app that allows users to meet new people nearby. It's not exclusively designed for dating, so users can find both friends and potential romantic interests.
The effectiveness of these apps for making friends can vary depending on factors like location, user demographics, and personal preferences. If you are specifically looking for friends, Bumble's BFF mode may be the most suitable option, as it's explicitly designed for that purpose. However, it's always a good idea to try out different apps and see which one works best for you based on your experiences and the types of people you come across. Keep in mind that regardless of the app you choose, online interactions should always be approached with safety and caution.
