Portable ECG & Warning Sign Detector

WIWE is more than just a portable ECG (electrocardiogram). Using powerful software, it is able to monitor and analyse your vital signs and flag any early warning signs of arrhythmia, stroke and sudden cardiac arrest (SCA) risk-assessment in just one minute. These results can then be sent directly to your GP or specialist for further analysis.

The credit card-sized device measures blood oxygen (SP02) and heart rate and then analyses that information via the free WIWE app (Available on iOS 8.1+ and Android 5.0+) in order to warn users of any potential warning signs. This allows potential at-risk individuals to monitor themselves without the need for medical professionals, providing safety and self-confidence.

It’s a sad truth that most cases of SCA result in death within minutes. By identifying warning signs effectively and quickly, WIWE hopes to change these shocking statistics for the better.

Smart Analysis

The WIWE uses a worldwide unique intelligent algorithm which evaluates the properties of the ECG wave to calculate if there is a risk of afib-related stroke and sudden cardiac arrest. If we know about it, we can change it!

ECG Recording

One of the main features of WIWE is ECG recording. Throughout the analysis, the outstanding noise filtering helps to get the best possible results. The evaluation calls your attention to any possible abnormalities detected in your ECG wave.

Pulse Oximeter (Sp02)

Healthy or sick? Blood oxygen level is a very important indicator, which can inflict moderate exhaustion, but there are many severe diseases caused by oxygen insufficiency. Stroke is he second leading cause of death worldwide.

WIWE Functions


Assessing ECG signals recorded in 60 seconds based on an accurate algorithm.


Assessing the regularity of heart rate or arrhythmia, which can lead to atrial fibrillation in some cases (and also can cause stroke).

Heart rate

Number of heartbeats in a minute also can describe the cardiac function.


Investigates ventricular re-polarisation heterogeneity, which describes the state of bio-electrical connections between heart muscle cells. Sharp deterioration may lead to severe ventricular arrhythmia’s, also sudden heart arrest or attack.

Oxygen saturation

Assessment of SpO2 takes place during the 60 second ECG recording. A low value may cause oxygen deficiency in the brain, muscle, major organs, cells, etc.


Plots ECG curve and alerts the user to any potential deviations.
Extensive information is available for review by a professional.

Ventricular Heterogeneity

Determines the electrical instability of cardiac muscle cells.
This can present warning signs of Sudden Cardiac Arrest.

Arrhythmia Examination

Examines fluctuation of heart rhythm, which can be an indicator of Stroke, Arrythmia and atrial fibrillation.
