For a quick health check, the smartphone camera will soon suffice at DocMorris. After just 30 seconds, the app displays several vital signs, but similar methods still have weaknesses in measuring blood pressure.
The online pharmacy DocMorris is offering a new vital signs check in its app. You hold the smartphone about 30 seconds in front of your face. The camera is supposed to capture pulse, blood pressure, and respiration. According to DocMorris, a blood pressure cuff or other additional devices are not required.
The technology is provided by the German company Caire Health AI. It uses minimal changes in blood flow in the skin. With each heartbeat, the light reflection of the skin changes. The human eye does not perceive these differences, but the software can capture them via the smartphone camera and calculate various values from them.
AI Takes Over the Evaluation
An artificial intelligence (AI) evaluates the image data according to DocMorris directly. The app does not store the video recordings, according to the company. DocMorris does not specify which software version of Caire Health AI is used, so it is not possible to estimate how accurately the new function works based on other products from the provider.
The vital signs check is primarily intended to provide a quick and uncomplicated overview. Users need no additional equipment other than the smartphone and receive several values after a short time. However, noticeable results should be verified with an appropriate measuring device or by a doctor.
Study Shows Weaknesses in Blood Pressure Measurement
Researchers examined how accurately similar methods work in a study published in 2025 in the journal “Digital Health” with 562 adults. They did not test the DocMorris function but the similarly operating app Comestai. Initially, participants sat quietly for two minutes. Then the researchers filmed them for about one and a half minutes under consistent lighting.

For pulse, the app was on average about three beats per minute off from the value of the comparison device. Larger differences were seen in blood pressure. For the upper blood pressure value, the app deviated on average by about 14 millimeters of mercury (mmHg). This could result in high blood pressure going undetected or being falsely assumed. However, the study results cannot be directly applied to the new DocMorris check.
