Consumers have spent two decades accepting wearables that log what happened. The90, RunSafePro, and Drexel's BioCoach team represent a harder shift: wearables that intervene while it is happening. The distinction matters commercially because it changes the product's relationship to time. A device that records is useful in retrospect. A device that responds in real time earns a place in daily behaviour.
The macro conditions that made this cohort possible are structural. Sensor miniaturisation has reached a point where UV detection fits inside a pendant necklace. Computer vision pipelines powerful enough to estimate 3D skeletal positions now run on consumer-grade video hardware. Mobile connectivity has normalised the idea of a device pushing a notification mid-activity. And pandemic-era data hardened the brief: at-home exercise injuries rose 48%, and a documented 92% of women runners reported feeling unsafe running alone. These are not soft consumer preferences. They are measurable gaps.
The90, founded by Stacy Salvi, who previously worked on the Fitbit acquisition by Google, launched The90 Gem in June 2026. The pendant necklace contains a sensor measuring live UVA and UVB radiation and syncs with a companion app that builds a personalised profile from skin type, sunscreen use, and clothing habits. The device then pushes timely reminders to reapply sunscreen throughout the day. Priced at USD 299, the product targets women as its first cohort, with plans to extend the line to men and children. The signal here is the conversion of a one-time morning ritual into an ongoing, responsive system.
RunSafePro launched on Kickstarter in June 2026 from the Netherlands, with a smart vest that keeps safety features running passively throughout a run. Rear radar detects approaching vehicles and alerts the wearer through lights and vibration. If a runner stops moving and fails to respond to an automated check-in, the vest dispatches GPS coordinates to up to 50 pre-selected emergency contacts. Early Kickstarter pricing started at USD 119, with a planned retail price of USD 175 and a companion app subscription from USD 0.99 per month. The vest is breathable, washable, and designed to pass as standard performance gear.
BioCoach, presented in June 2026 by researchers at Drexel University and Michigan State, applies computer vision and biomechanical modelling to at-home exercise. The system estimates 3D skeletal positions through a standard video feed, assesses joint angles and ranges of motion for movements like squats and push-ups, and delivers specific corrective cues via a language model, including the biomechanical rationale for each adjustment. Trained on a new dataset of over 2,400 annotated biomechanical notes, BioCoach outperformed feedback systems from major tech companies in accuracy tests. The team plans to adapt the prototype for consumer fitness and physical therapy applications.
For brands across sportswear, suncare, insurance, and physical therapy, the opening is in the data and subscription infrastructure beneath the hardware. The sensor earns access. The ongoing service earns revenue. Any brand with an existing reason to sit close to the body now has a credible architecture to build from.
