Health becomes a habit. Habits keep users.

Most health features ask users to wear something, log something or wait for something. A face scan asks for 30 seconds and pays back immediately. That trade is why people come back.

Why choose Shen AI to boost engagement

Steps and sleep are passive. A face scan is an act, and it returns something new every day. Offer daily health checks and users open the app because the check-in is worth 30 seconds. Apps with Shen AI inside report up to 350% higher retention.

The first scan turns a sign-up into a believer. Blood pressure, heart rate and a wellness score from a selfie camera, live, in the session they signed up in. Partners describe the demo as a clear wow. Onboarding conversion follows.

Streaks only work when the thing you track changes. Wellness score, HRV, stress index and blood pressure move day to day and week to week. Users see progress, and progress is what keeps a habit alive.

A skipped scan, a drifting trend or a great week are all reasons to reach out. Trigger reminders, coach messages and rewards from what the data says. Silence when things are fine, which is what makes the nudge land when it matters.

Gate the scan or the trend history behind premium tiers. Personalize offers and wellness upsells with health insights. Show insurers and employers engagement data that proves the value of your program.

Science-backed health monitoring inside your app is a feature competitors cannot copy over a weekend. Clinically validated, CE-certified vital signs, all skin tones, any camera. Live in days.

The daily check-in loop

Engagement is a loop, not a feature. Shen AI supplies the moment worth returning for, the scan and the result. Your product wraps it in triggers, progress and rewards. Once a day, 30 seconds, and the loop closes on its own.

Steps 2 and 3 ship with the SDK, white-label, in your colours and 24 languages.
Steps 1, 4 and 5 are your reminders, streaks and nudges, built on the results the SDK returns.
Every pass through the loop adds a data point. Trends get richer, nudges get smarter.

  • Objective wellness data for programs and rewards
  • Continuous monitoring without wearables or clinic visits

Lift participation across the workforce

Most wellness programs stall on participation. A 30-second scan on any laptop or phone removes the excuse. Employees get a daily check, you get engagement and outcome data for the board.

  • No devices to buy or ship
  • Team challenges built on real health data
  • Lower absenteeism and turnover as measurable outcomes

Make adherence visible, weekly

Therapy programs live or die on persistence. A scan tied to the dosing day gives patients a reason to open the app and gives care teams vitals between visits. See how it works for GLP-1 programs.

  • A ritual tied to the dosing schedule
  • Vitals and symptom check-ins in one flow
  • Early warning when scans stop

Frequently asked questions

What product teams ask before adding AI health monitoring.

It gives users a reason to come back that pays off every time. The scan takes 30 seconds, needs no wearable and returns 30+ health markers with a score that moves. Apps that added Shen AI report up to 350% higher retention, and partners describe the scan as their most used feature.
