About the app
01
Psychological Compatibility Tests
Upon registration, every user takes a short Big Five test. It identifies the most important personality traits and the tendency to behave in similar ways across different situations. We use these traits to calculate compatibility.
Later on Twinby, users can also take MBTI personality type and Jung attachment style tests. These tests make matches more accurate. Every few years, we expand the set of available tests.
02
Feed with Potential Partners
After registration, users get access to a feed of other profiles. They can set partner criteria using filters, give likes and superlikes. A distinctive feature of the profiles in the feed is the compatibility percentage, which can even be 100%.
03
Compatibility
Swipes on Twinby are intentional, not just based on photos. Compatibility levels are calculated from completed tests and shown immediately in the feed. After a match, you can instantly see where the couple is highly aligned and where more attention is needed.
Over time, accumulated analytics allow us to further optimize recommendations.
