“I was blown away the first few times we talked on the phone,” said one half of a newly formed Los Angeles couple, who asked to remain anonymous, “We clicked right away on so many levels!”

The couple, who are 25 and 26, had never used dating apps and weren’t keen on the idea - until they stumbled upon So Syncd, and both felt curious about the way the app connected people using personality types.

Based on the Myers-Briggs personality type indicator, the app lets you take a free five-minute test before assigning you a personality description - you can then choose to search for other personality types, if you are familiar with Myers-Briggs, or else let the app choose for you.

The Los Angeles couple both already knew their Myers-Briggs personality types - INFJ and INFP, or “So Thoughtful” and “So Unique” according to the So Syncd app - which gave them a 90 per cent compatibility rating.


Sparks certainly flew when they got talking, bonding over their shared passion for learning, and both priding themselves on knowing “a lot of random things". Within days of their match the pair were FaceTimeing every day - sometimes multiple times a day - so they already knew each other pretty well when they first met in person a month later.

She said: “It was just so affirming to experience each others’ company in person after a lot of suspense. We have some different interests and preferences, but the same values and a similar way of seeing the world. Two days later he officially asked me to be his girlfriend.”

Jule, an 18 year old student from Hamburg in Germany, met Christoph, a 22 year old IT apprentice from Bonn, also in Germany, just days after she spotted the app on an Instagram ad in October. Despite having the same personality type - INTP, or “so logical” - the pair were an 88 per cent match on So Syncd.

Both self-proclaimed introverts, they were shocked to end up talking for eight hours straight on their first Zoom date: “It was the middle of the night and it was like five minutes passing by,” said Jule, adding that meeting in person for the first time after only talking on Zoom was incredibly strange.

She said: “I got off the train, and at first I thought I was being scammed, and I’d have to sleep in the train station. Then I saw him - he didn’t say anything, he just hugged me - he squeezed me a lot, it felt like suffocating - but it was amazing.”

“Yeah, I kind of f*** that up,” laughed Christoph, “I was very nervous, I’m not much of a talker, so I just  hugged her very, VERY hard.”

So are personality types really the best indicator of whether people are a match?

Definitely, according to Londoner Jess Alderson, the 30-year-old co-founder of So Syncd.

She said: “Our overall thesis is that we pair couples with just the right amount of similarities to form a strong connection, but just the right amount of differences to create a spark.”

She added: “If you’re too similar it can just be a bit boring and you don’t really learn from each other, you don’t push each other out of your comfort zone, you don’t grow - but then if you’re too different it’s quite hard to find things to connect over.”

Say goodbye to awful Tinder matches

Jess came up with the idea for So Syncd with her sister Lou, 27, whilst they were out for drinks one evening discussing a series of terrible dates their friends and family had been on - it suddenly occurred to her that she knew a better way of matching people.

Jess had been interested in personality types for years, but had never thought to apply them to relationships until a bad breakup left her questioning how something so good could have ended up so bad.

She took a year out to travel, during which she spoke to many people about their personality types and their relationships, trying to figure out patterns in what she saw - three years later, these chats would become the basis of her market research for So Syncd.

The sisters spent the majority of 2019 building the app alongside their day jobs. In the process Lou discovered she had already been in a long-term relationship with her perfect personality match - 100 per cent compatibility - for years without even realising it. The app was eventually launched in lockdown this year - perfect timing, according to Jess.

She said: “People are just so in need of meaningful connections and a lot of people are just very lonely, particularly if you live by yourself. It’s been really nice to be able to help people - now we get messages from people pretty much most days, saying things like ‘you helped me find my soulmate'.”

Jess said it helps that people on the app tend to be looking for a similar thing: “If you’re going to spend the time to do a personality test, it’s not like you’re looking for a short term hookup.”

The formula isn’t set in stone, she added: “We would never say a personality mismatch could never work out - that’s not what we want to do, we don’t want to stop people dating because of a personality type - we really just want to increase people's odds of finding love, that’s what it comes down to.”

So Syncd has a growing user-base of 30,000 people, which Jess puts down to word of mouth about their high success rate - she was excited to share the news of the app’s first confirmed wedding.

As well as continuing to grow their user base, the sisters have other ambitions for the app’s future - not content with drawing the line at romance, they hope the high quality of connections it promotes will translate well to their new friend-matching feature, in the pipeline for 2021.
