Kaytlin Neil is making headlines once again—and this time it’s not for a brutal knockout or a hard-fought decision victory. The PFL flyweight just posted something on social media that has the MMA world buzzing with intrigue. It’s sleek, modern, and promises to forever revolutionize the way fighters practice. While fans tried to figure out what she was talking about, one thing was certain: this was no ordinary fitness promotion. It was a glimpse into what the future of fight prep could look like.

Neil teased a new tech-driven tool with a simple caption: “FINALLY! 🤩 A mouthguard that tracks your workout stats. Comment ‘MOUTHGUARD’ and I’ll send you the link!” That’s right, it’s not a watch or a ring, but a smart mouthguard. And it’s not a gimmick. ORB Sport created the custom-molded mouthguard, which not only protects teeth but also gathers over 20 performance parameters via embedded sensors.

It monitors everything from heart rate zones and calories burnt to activity intensity and head impact data, which is synced in real time with a companion app. For someone like Neil, who’s been grinding through the flyweight ranks with a 7-5 record and a reputation for cardio-heavy, technical bouts, the appeal is obvious.

The option to access real-time data during training or study it in detail later is invaluable for athletes wanting to make the most of each session. Kaytlin Neil, an MMA fighter and fitness instructor, understands the importance of precision, and she’s made it clear that she wants her audience to benefit from it as well.

Combat sports have been using smart equipment for quite some time. UFC fighters have already embraced equipment such as punch trackers, smart gloves, and wearable rings to track everything from sleep to recovery. But the ORB mouthguard does something unique. It’s one of the few devices that can detect genuine in-fight hits while maintaining performance. That is the kind of innovation fighters and coaches have been looking for. But what do the fans think of it?

Kaytlin Neil’s new tech raises several questions on social media

Kaytlin Neil’s introduction of the new mouthguard technology to her followers sparked more than simply intrigue; it opened the floodgates. The fighter had been building up the excitement, and when the curtain eventually lifted, fans were treated to more than just a gadget reveal. It was a combination of MMA grit and sci-fi promise, all packed into something as simple as a mouthguard. Naturally, questions flooded in. Some were curious. Some were skeptics. Others, as one could expect, got a little weird. But everyone was talking about it for sure. One of the first waves of reaction came from fans trying to figure out what exactly this tech could and could not do.

“Funny but serious question: can it track how many hits you take to the face where the mouth guard is?” one fan asked, to which Neil honestly replied, “Unfortunately, no.” The product’s creator later clarified that, while it does not provide an exact hit count, users can observe “spikes on a graph” to detect effects. It’s not perfect, but it’s a step closer to understanding the invisible toll of a fight.

Then came an influx of fans who were just impressed. One described it as “wild tech for MMA,” while another joked about using it for cardio: “Gonna use this during cardio training with local birds.” Some older fans reminisced on the evolution, stating they were shocked at how far things had progressed. “Damn, I just had one made at the dentist back in my day; now we’ve got ones that track us. Wow,” the user wrote.

One fan joked, “I totally understood what you were saying with the guard in. It’s its own language,” while another said, “That’s some wild tech for mma.”

To them, it didn’t matter how many sensors the device had or whether it could withstand a crazy fight experiment. It was about seeing a sport they enjoyed gradually evolve into something smarter, sharper, and unquestionably more advanced.
