This product is not for everyone. It is most useful when you have enough real interaction to observe patterns, but still feel uncertain about what those patterns mean.
People in situationships, early dating stages, ambiguous reconnecting, emotionally uneven pursuit, or repeating communication loops often get the most value from it.
The best fit is someone willing to answer honestly, tolerate ambiguity, and use the result as a way to slow down and observe better rather than as an excuse to force a conclusion.
