The Scoop: Finding true compatibility can seem elusive to the average single person, but some online dating apps have used psychology to make things easier. So Syncd is a groundbreaking dating app that matches users based on Myers-Briggs personality testing. So Syncd launched in 2020 and gave singles in lockdown a smarter way to match and date online. This science-driven dating app has caught the eye of more than 30,000 users in the U.S. and the U.K., and it has already sparked many compatible dates and meaningful relationships.

Compatibility is a key part of a successful relationship, but it’s not always easy for singles to pin down who is good fit for them. Some swiping apps only add more confusion and chaos to the system by highlighting profile pictures over in-depth bios and encouraging superficial choices in the online dating world.

Launched in 2020, So Syncd aims to do better by its users and provide science-based compatibility recommendations. This dating app is based on the Myers-Briggs personality test.

So Syncd is a new dating app that is taking online dating in a new direction.

The test outlines personality types based on the psychological principles of human behavior developed by Carl Jung in the 1910s. The Jungian Archetypes explored the idea of the unconscious mind and how it influences behaviors.

In the 1960s, psychologist Isabel Briggs Myers and her mother Katharine Briggs created a four-factored personality breakdown that made Jung’s theories more accessible to the general public. These 16 personality types have become part of the vernacular to such a degree that it’s not unusual to see people proclaim themselves an INFJ or ESTP in a dating profile.

Now, So Syncd has taken the next logical step and used the Myers-Briggs theory to inform and inspire its potential matches. Sisters Louella and Jessica Anderson co-founded the app as a solution for relationship-oriented singles. The app leads its users to romances and friendships that made sense on a psychological level.

Louella said she did a lot of research on the Myers-Briggs personality types and applied them to her own life to see if they held up. “Without even realizing it, I had been in a long-term relationship with someone who was my ideal personality type match,” Louella said. “It made so much sense.”

By harnessing the wisdom of the Myers-Briggs test, So Syncd can help single people better understand themselves and choose a compatible partner who will be in sync with them in a relationship.

Inspired by a Year of Research and Travel

The idea for the So Syncd app was sparked by a breakup, a soul-searching journey, and a girls night out. It all started when Jessica, who was working as an investment banker in London, decided to move to Sydney to be with her Australian banker. Eventually, she changed jobs and the relationship ended.

Jessica decided to use this as an opportunity to travel. She spent a year seeing the world and giving a lot of thought to the mysteries of the heart and why certain relationships work while others don’t.

Sisters Jessica and Louella were inspired to create So Syncd to improve the quality of AI matchmaking.

“Because I had this breakup, I started analyzing it from a personality perspective. That’s what sparked my interest of applying personality types to dating,” she said. “Over that year, I obsessively read things about it and talked to people I met while traveling, observed relationships. I did a deep dive into personality types and love.”

Jessica returned to London with new insights, but no idea what to do with them. Until one night she shared drinks with her sister and exchanged dating app horror stories. The sisters realized online dating wasn’t working for them or their friends, and they talked about the factors that really mattered in a relationship.

By the end of the night, their business was born, and they began working on So Syncd.

So Syncd is a unique app where mutual matches are the result of rigorous testing and proven psychological principles. The So Syncd blog explains how the personality types are organized based on four major dichotomies: extraverted versus introverted, sensing vs intuitive, thinking vs feeling, and judging versus perceiving.

Some of these personality types mesh well together — the thinking person can benefit from the heartfelt insights of a feeling person and vice versa. While other combinations may spell trouble. For instance, when two judging personality types (meaning structured, not judgmental) pair up, the relationship can lack spontaneity.

“It just works,” Jessica said of the So Syncd matchmaking system. “Some personality types really do just work out better for romantic partners.”

The So Syncd app launched in 2020 just before the COVID-19 pandemic hit. Despite the lockdowns and uncertainty of its early days, So Syncd managed to make a solid opening campaign and help a lot of singles hit things off. To date, the app claims responsibility for over 300 love stories, including a French woman and British man who met on the app and recently got married.

“That was the most exciting moment by far,” Louella said. “We’d been in touch with the couple, and they kept us updated. They’re almost friends.”

Users Take a Short Test to Find Their Type

So Syncd started in the U.K., but it is rapidly taking hold of the American dating scene as well. The majority of its users are young singles living in New York and California. The app seems to attract many serious relationship seekers, and it doesn’t have a bias toward one gender or another. In fact, Jessica told us the gender split is exactly 50-50.

“It’s quite rare to have that on dating app. It’s usually two-thirds men,” Jessica said.

The So Syncd app matches users based on personality types rather than looks.

Downloading So Syncd is totally free, and the signup process takes less than 10 minutes from start to finish. The longest part of the process is the five-minute personality quiz, which is the app’s take on the Myers-Briggs test. Be sure to be honest in your responses to the multiple-choice questions because those answers are the basis for every match made in the app.

“You get a profile and take the test to learn your strengths and weaknesses and how you are in a relationship,” Jessica explained. “Then, you’ll get your ideal date recommendations.”

The personality test results separate singles into distinct categories that include idealists, rationals, guardians, or explorers. The spectrum of personality helps individuals know themselves and know what to look for in a good match.

Once the profile and personality testing is complete, users will be able to see the photos, personality types, and other information about potential matches. So Syncd calculates a compatibility percentage based on the personality quiz results and profile information.

App users can only send messages to someone they have matched with, but So Syncd offers unlimited matches and unlimited messaging for free.

“We don’t want our users bombarded with low-quality likes and bad matches,” Jessica said. “Users give us feedback that they haven’t had this many good matches on any other dating app, and that’s exactly what we want to hear.”

So Syncd Creates Connections for Friendship and Romance

Louella said she really appreciates and enjoys working with her sister, even though, interestingly enough, they aren’t a perfect match on the Myers-Briggs test.

“We’re the opposite personality types and have complementary skill sets,” she said. “But working with my sister has been really great. We completely trust each other and can be honest with each other. We’ve had a lifetime of practice.”

Looking to the future, the sisters have big plans for expanding So Syncd and promoting a quality-driven way to make a date. Or make a friend. The sisters have gotten a lot of feedback from users saying they’d like to use the Myers-Briggs test to form friendships, so the next development project in the works is a feature that will specifically search for and match potential besties in platonic relationships.

“We talked to a lot of members and all would love to use the app to meet friends as well as dates,” Jessica said. “Some do already. We want to separate that out and make it a bit clearer for people.”
