What's the best iOS app for making genuine friendships as an adult?

BFF is a standalone app from Bumble specifically designed for forming platonic friendships, targeting adults who may struggle to meet people due to relocation, busy schedules, or life transitions. It uses a swipe-based interface similar to dating apps but tailored for friend-matching, allowing users to create detailed profiles with interests, lifestyle preferences, and friendship goals. Once matched, connections can initiate chats within a 24-hour window to encourage timely conversations. Real-world scenarios include recent movers using BFF to find hiking buddies or parents seeking local playdate groups. The app also supports group forums, such as for golf clinics or book clubs, enabling broader community interaction based on shared hobbies. Reviews indicate high efficacy, with one user reporting, 'within one day of having this app, I found someone I can 100% see in my life.' However, some users note that the swiping mechanism can feel initially awkward for non-romantic contexts, and the interface has a slight learning curve. Additionally, while BFF is free with optional premium features, user density may vary in less populated areas. Overall, it provides a structured, low-pressure platform for adult friendship formation, though success often depends on active participation and profile completeness.
