July 8, 2025 — In a landmark decision poised to transform hypertension management, Swiss medtech company Aktiia has received FDA clearance for its groundbreaking cuffless blood pressure monitor. The wearable device, worn like a standard fitness band, promises 24/7 blood pressure tracking without the need for traditional inflatable cuffs—a first for over-the-counter (OTC) use in the U.S.
The Aktiia monitor uses photoplethysmography (PPG) sensors—similar to those in smartwatches—to measure blood flow patterns at the wrist. Combined with proprietary algorithms calibrated via initial cuff-based readings, it generates clinical-grade BP data during daily activities and sleep. This continuous approach addresses a critical gap in hypertension care: "White-coat syndrome" (elevated readings in clinical settings) and sporadic measurements often miss dangerous fluctuations.
Dr. Elena Rodriguez, a cardiologist at Johns Hopkins, emphasizes the impact: "50% of hypertension cases go undetected. A cuffless device that passively monitors could save lives by catching nocturnal hypertension or medication inefficiencies early." Aktiia’s validation studies demonstrated accuracy within ±5 mmHg of invasive arterial line measurements—exceeding FDA thresholds.
Why This Matters
- Accessibility: No more squeezing cuffs during work meetings or midnight wake-ups.
- Data Depth: Trends over time reveal more than spot checks, aiding personalized treatment.
- Global Momentum: Following CE Mark approval in Europe (2021), U.S. clearance paves the way for insurance coverage.

The Road Ahead
Aktiia plans U.S. consumer availability by Q4 2025, priced at $199. Competitors like Samsung and Apple are racing to develop similar tech, but Aktiia’s FDA-first status gives it a critical edge. As wearable health tech shifts from fitness to medical legitimacy, Aktiia’s win signals a new era: one where managing chronic conditions becomes as effortless as checking the time.
"This isn’t just a gadget," says Aktiia CEO Otti Vollenwyder. "It’s a bridge to proactive healthcare—empowering people to own their heart health, silently and continuously." For 108 million U.S. adults with hypertension, that bridge can’t come soon enough.
