A UK-based digital health company has become the first globally to be certified for a blood pressure smartphone app that does not require a traditional cuff.

Lifelight's revolutionary mobile app uses only a smartphone camera to measure blood pressure accurately, a possible revolution in how we screen for and track cardiovascular disease.

Lifelight App Brings Clinical-Grade Blood Pressure Monitoring to Your Smartphone

By eliminating the need for in-person appointments, clunky equipment, and costly processes, Lifelight's solution cuts the barriers to cardiovascular screening dramatically. Its purpose is simple: make early diagnosis of high blood pressure quick, easy, and scalable—right from the phone in your pocket.

The innovation is timely. Two of the most expensive and widespread long-term conditions the NHS is facing are hypertension and cardiovascular disease. The app from Lifelight has the potential to support more preventative work, reducing system burden and individual health risk.

How It Works: AI + Smartphone Camera = Accurate Blood Pressure Readings

At its core is remote photoplethysmography (rPPG), a technique that tracks minuscule colour shifts across the face—"micro-blushes" caused by fluctuations in blood flow.

These minute fluctuations are detected by a smartphone camera before being processed through Lifelight's proprietary AI models to deliver clinically validated systolic and diastolic blood pressure measurements.

While rPPG technology itself is not new, Lifelight has innovated the technology with a clinically validated dataset of over 25,000 video recordings and blood pressure pairs. Their AI was also trained using data from a diverse patient population of 12,500 patients, and the system is protected by six patents.

Proven Impact: Already in Use by 100,000+ Across UK and Europe

Lifelight's app has already found widespread popularity, with over 100,000 users across the UK and Europe. It has been used in NHS pilot programs—such as the Hampshire and Isle of Wight Integrated Care Board—and integrated into well-known sites such as iPlato's myGP app.

The technology is also being piloted by insurers, digital healthcare operators, and virtual ward programs, specifically for managing chronic illness and remote screening.

CEO: “As Significant as the Smartphone Camera Was for Photography”

“This is a moment as significant as the smartphone camera was for photography. For the first time, we’ve put GP-level blood pressure monitoring into the smartphone in your pocket,”

 — Laurence Pearce, CEO, Lifelight

Pearce pointed to Lifelight's potential to eliminate unnecessary GP visits and free up clinicians from less urgent cases. With Health Secretary Wes Streeting valuing preventable care through the NHS on a scalable basis, Lifelight sees itself as a good match for national health policy aims.

Lifelight estimates that 15% of Europeans are walking around with undiagnosed high blood pressure, although 80% of cardiovascular disease is preventable.

Their application is compatible with 10-year-old phones, and thus it reaches 80% of all users globally. It does not require cuffs, wearables, or the need to train, and it can be especially valuable for people with obesity, mobility impairments, or difficulties using conventional blood pressure devices.

Being Compliant with NHS Aims for Prevention Health

With the NHS placing greater emphasis on preventative care and about to roll out a national cardiovascular screening program, such technologies as Lifelight are going to shape the future. With clinical-grade blood pressure readings offered at no charge, without delay, or complication, Lifelight can potentially mainstream early cardiovascular screening.

In a nutshell: Lifelight's cleared app is not just the world's first digital health app but potentially the template for scalable, preventative cardiovascular medicine—turning every smartphone into a medical-grade tool.
