Boo World has a clear appeal: if you're someone who cares about MBTI compatibility, it gives you a way to filter potential connections by personality type right from the start. But MBTI type is a fairly narrow filter. Two people with the same four-letter type can have very different values, life stages, and communication styles. For users who want matches based on more than a label, here's what else is available.
Boo World
Boo World is a social and connection app centered on MBTI personality types. Users enter their type, browse others by type, and connect for both friendship and dating. It has an active user base among personality-type enthusiasts and works well as a discovery tool for that audience. The limitation is that MBTI compatibility is a starting point, not a full picture of whether two people will actually click. If you find that the connections you make through Boo don't go anywhere meaningful, the issue is often that type alone can't predict values alignment or communication fit.
Bumble BFF
Bumble BFF is the most widely used dedicated friendship mode in the market. It operates as a swipe-based app, which means large user volume and easy onboarding. The trade-off is similar to any swipe app: high volume, lower signal on depth of compatibility. It's a strong starting point if you want options and are comfortable filtering yourself, and it works well in large cities where the user base is dense.
Friended
Friended is a friendship app that leans into interest-based community features alongside one-on-one matching. Users can join topic-specific rooms as well as match directly with individuals. The community layer makes it more forgiving for people who aren't comfortable jumping straight into one-on-one conversations. It's a reasonable option if you're trying to find people who share a specific hobby or interest before moving toward individual friendship.
Meetup
Meetup is worth mentioning because it solves a different part of the problem than individual matching apps do. Rather than pairing you with one person, it places you in a recurring group around a shared interest. The repeated contact that Meetup enables, seeing the same people week after week in a low-pressure context, is one of the most reliable mechanisms for adult friendship formation. If you're open to the slower pace of group-based connection, it's still one of the best tools available.

Introvrs matches you on who you are, not your photos. Free during early access.
Introvrs
For users who came to Boo World because they wanted compatibility beyond surface-level interests, Introvrs takes a different approach entirely. It doesn't use MBTI as a matching criterion. Instead, it assesses your values, your life stage, and your way of thinking through a confidential AI-powered onboarding conversation at bestie.introvrs.com.
Introvrs then sends one match at a time, with evidence-based reasoning for why you were paired: what you have in common, what you've both been through, and what kind of friendship you're both after. You're not running through the same surface-level questions with someone you have nothing real in common with. You already know why this person is worth your time.
This is the right tool for depth-seeking users who want one well-reasoned connection over a stack of undifferentiated profiles. Learn more about how AI-assisted friend matching works. Free during early access at introvrs.com.
FAQs
What is the Boo World app?
Boo World is a social and dating app that uses MBTI personality types as a compatibility framework. It lets users filter and discover connections based on their four-letter MBTI type. It's positioned toward personality-type enthusiasts and has both friendship and dating modes.
Is Boo good for making friends?
Boo can work for making friends, particularly for users who are interested in MBTI and enjoy that framing for compatibility. The limitation is that MBTI type alone is a fairly narrow filter. People with the same MBTI type can have very different values, life stages, and communication styles. If you want compatibility based on who you actually are rather than a four-letter code, you may find the matches less useful.
What are the best alternatives to Boo World?
The best Boo World alternatives for adult friendship in 2026 include Bumble BFF (large user base, broad appeal), Friended (community and interest-based), Meetup (activity and group-based), and Introvrs (one match at a time, full values and life-stage compatibility assessment, evidence-based pairing).
How is Introvrs different from Boo?
Boo World matches people based on MBTI compatibility. Introvrs doesn't use MBTI as a matching criterion. Introvrs assesses your values, your life stage, and your way of thinking through a confidential AI-powered onboarding conversation, then sends one match at a time with evidence-based reasoning for why you were paired. The goal is depth, not type-based browsing.
