How it works
Tap your type and the other person's type, add names if you like, and hit Check compatibility. The score counts up, then the result card opens with the strengths of the pairing, the likely friction points and two practical tips. Below it, every one of the 16 types is ranked against yours; tap any row to switch to that pairing.
How the score is built
Each letter pair is compared separately. Sharing the same way of taking in information (S or N) adds the most, because it shapes how easily two people follow each other's conversation. Opposite energy (E/I) and opposite lifestyle (J/P) add points as complements. Pairs that share S/N but flip both E/I and J/P get a bonus, and a handful of famous pairings, like ENFP with INFJ or ENFP with ISTJ, get their own write-up.
So ENFP and INFJ land in the 90s, while ENFP and ISTJ, which differ on all four letters, land in the 50s.
Compare with a friend
Send the result with Share. Your friend sees your pairing first, then taps Check my type with... to see how they score with you, and the page shows both numbers side by side. Save image turns the result into a card sized for group chats and stories.
Keep it light
MBTI sorts tendencies into 16 types; it is not a scientific predictor of relationships, and this score follows our own simple rules. Low-scoring pairs make great couples and friends all the time. Use the friction points as conversation starters. For other fun matches, try the name compatibility test or the zodiac sign finder.
