Chemistry is founded on an algorithm created by Dr. Helen Fisher. The algorithm ensures that users’ personality type is discovered after taking the personality and hormone-based test upon registration. Users are matched with other users based on their personality types. Chemistry.com ensures that users do not have to go through the difficulties associated with finding a compatible partner. The dating site carries on the bulk of the scouting process by matching users based on compatibility and Chemistry and leaves them to take it up from there.
