How camera-based health insights drive better habits, outcomes, and retention

‍

In today’s digital health landscape, keeping users engaged remains one of the biggest challenges. Many apps see promising download numbers - only to experience a rapid drop in regular use. But this isn’t just a user behavior issue. It reflects a deeper disconnect: when technology doesn’t deliver clear, everyday value, people naturally stop using it.

It’s discouraging for developers who invest significant effort into building great tools only to see engagement fall short. And in healthcare, low engagement doesn’t just affect adoption metrics, it can mean missed opportunities to support clinicians and improve patient outcomes.

To truly empower people, we must move beyond quick, surface-level use. In this context, engagement is the foundation of meaningful, data-driven care. Without it, even the best digital tools struggle to make a lasting difference. When apps deliver real value, engagement sparks lasting habits and deep understanding over time. Without this bond, even brilliant health solutions become digital clutter. 

The solution: make health monitoring so simple, quick, and personal, it is a joy to use.

This is the exciting promise of AI health monitoring. It transforms familiar tech into a powerful tool for consistent, easy, and truly meaningful patient involvement. It's a vital step towards "Deep Medicine," where data empowers people, saves time and money, and strengthens human connections in healthcare, rather than replacing them.

When health checks take seconds, habits stick

At its core, AI health monitoring represents a meaningful shift in how we access and use health data. Accurate information is essential for clinical decisions, and this technology makes collecting it easier than ever - using nothing more than a smartphone camera.

Imagine being able to view real-time health indicators before a consultation even begins. No need to rely on patients remembering to use home devices. What once felt like science fiction is now possible - thanks to technology built on large, diverse datasets and validated for accuracy and consistency.

The real advantage lies in its simplicity. No wearables, no setup, no extra effort. Shen AI uses advanced AI to analyze subtle facial signals and deliver instant insights into vital signs, including:

- Blood Pressure 
- Heart Rate
- Breathing Rate
- Heart Rate Variability (HRV)
- Body Mass Index (BMI)
- Stress Index
- Vascular Age
- Cardiovascular Event Risk

And an ever-expanding suite of metrics, with ongoing additions like SpO2 and cholesterol risk.

Crucially, this method works for everyone. Shen AI’s technology is constantly updated across all skin tones and lighting conditions. It's a powerful step toward bringing smart, personalized health insights to everyone by using tech they already own. This smooth integration into daily life means healthcare for all, not just a few.

From data to habit

What turns an app into a lasting part of someone’s health routine? Often, it’s not just features - it’s the sense of agency it creates.

AI-powered health monitoring taps into an important need: to understand and take control of one’s own wellbeing. When people receive immediate, personalized feedback about their body - without needing extra hardware - they’re more likely to stay curious, engaged, and motivated.

This kind of feedback loop is simple but powerful: scan → result → insight → informed action. It builds habits organically, without the need for pushy reminders or intrusive nudges. Whether it’s watching stress levels respond to a mindfulness practice or seeing blood pressure improve with sustained effort, users can connect their choices to real, measurable progress.

That clarity fosters trust - and habit. Over time, it strengthens the relationship between the user and the platform, encouraging deeper, more consistent engagement. It’s not just about data collection; it’s about helping people feel supported, informed, and in control of their health journey. And when that happens, everyone benefits - from the user to the clinician to the entire care ecosystem.

Impact across the health ecosystem

The versatility of AI health monitoring means it integrates into and fundamentally redefines engagement across most healthcare applications, including:

Digital health platforms

‍Think of a blood pressure diary where users receive automated, daily scans without needing a cumbersome cuff. This would simplify managing chronic conditions like hypertension, diabetes, and many more, making it easier for patients to stick to their plans, providing continuous, high-quality data for clinicians, and enabling proactive, adaptive interventions. No more missed readings because a device was forgotten or too much trouble to use; the data is always there.

Wellness & stress management apps

‍Users can perform an immediate stress index check-in before a meditation session, gaining objective insight into their physiological state and validating the tangible effectiveness of their mindfulness practices. This moves beyond subjective feelings to objective biometric validation, helping users understand their body's response.

Employee health & corporate wellness programs

‍Daily scans before or after breaks can give employees real-time insights into their physiological well-being. When stress is detected early, it's easier to pivot and maintain a company culture that values health, happiness, and resilience. It helps employees feel seen and supported in their health, reducing burnout and improving overall happiness.

Fitness apps

‍Recovery tracking with Heart Rate Variability (HRV) allows athletes to improve their training regimens, prevent overtraining, and enhance performance based on real-time physiological readiness. No more guessing if your body is ready for another intense workout; the data simply tells you so you can make smarter training decisions.

Insurance apps

‍Think scan-based assessments integrated into incentive-based reward programs. As a policyholder, you could be rewarded for participating in preventive health initiatives. As an insurance company, it could help mitigate future claims and foster healthier populations at scale. It's a win-win: healthier members, smarter resource allocation, and a proactive approach to health.

Heartery: Scalable, engaging hypertension care

Heartery, a digital health app focused on hypertension care, faced a familiar challenge: how to keep users engaged long enough to make a real impact on their health.

With Shen AI, using just their smartphone camera, users can check their blood pressure, heart rate, and cardiovascular load in 30 seconds - no cuffs, no wearables, no friction. That ease of use helped Heartery deliver real impact from the start.

“Shen’s face scan is now our most-used feature, driving higher engagement and retention” says Leo Rosenbaum, co-founder of Heartery. “Users appreciate having real-time insights into their heart health without needing extra devices”. 

Since launch:

- Heartery reached 25,000 downloads and topped app store rankings for hypertension care in the UK, US, and Canada.

- They achieved a 30-day retention rate of 13%—3.5x higher than the average for health apps.

- Users report an average 2.5–3 mmHg drop in blood pressure after one month of regular use.

Heartery is showing how scalable digital health can deliver real results by putting effortless, accurate health tracking in users’ hands.

Making health monitoring simple and scalable 

The future of health monitoring isn’t coming, it’s already here. It’s device-free, smart, and built to meet people where they are.

By embedding AI health monitoring directly into smartphones and everyday devices, we make it easier than ever for users to check in on their health. No extra hardware. No complicated steps.
