STATEMENT

DISCLAIMER

Our application aims to support users in adopting a healthy lifestyle. However, it is not designed to function as a medical device or substitute for professional medical services. If you require medical assistance or diagnosis, we strongly recommend consulting your doctor or primary care physician. 

THE STATEMENT ABOUT HEALTH TESTS

• The tests within this application are intended to be used alongside professional guidance from a psychologist or therapist, as they are not standardized clinical assessments. Consequently, the calculated values and outcomes should not be interpreted as a means of diagnosis or as a comparison to the broader population. Rather, their purpose is to encourage individuals to engage in self-reflection. 

• It is recommended to take the test periodically. It is understandable that during challenging life circumstances such as divorce, workplace conflicts, or grief, your mental well-being may be reflected in lower test scores. 

• It is important to recognize that everyone experiences occasional difficult days where finding joy or inspiring thoughts can be challenging. Instead of fixating on unfavorable results, it is beneficial to view them as opportunities for growth and learning. 

BLOOD PRESSURE (BP) 

Blood pressure (BP) is the term used to describe the lateral pressure exerted on the walls of blood vessels per unit area during the flow of blood. It serves as the driving force that facilitates blood circulation within the blood vessels. Depending on the specific type of blood vessel, these pressures are referred to as arterial blood pressure, capillary blood pressure, and venous blood pressure. Typically, when we talk about blood pressure, we are referring to the arterial blood pressure within the systemic circulation.  Blood pressure below 140/90 mmHg is within the normal range.

BLOOD OXYGEN SATURATION(SAO2)

Blood oxygen saturation, refers to the ratio of oxygen-saturated hemoglobin in blood to total hemoglobin. The human body needs and regulates a very precise and specific balance of oxygen in the blood. The normal arterial oxygen saturation of the human body is 95-100%. If the level is below 90%, it is considered hypoxemia. Arterial oxygen levels below 80% may impair organ function, such as the brain and heart, and should be addressed promptly.

HOW DOES THE HEART RATE MONITOR WORK?

The application utilizes contact photoplethysmography, a technique that involves placing a finger on an integrated camera to detect variations in light absorption caused by pulsations in arterial blood volume. 

To simplify the explanation, our software utilizes the built-in camera of your phone to measure the light reflected from your blood, enabling detection at any given moment. As your heart beats, there is an increase in blood flow, resulting in greater light absorption. Conversely, during the intervals between beats, there is a decrease in light absorption. By analyzing this recurring pattern, our program can effectively track and analyze the frequency of your heartbeats, providing you with precise pulse readings and results.

HOW DO WE EVALUATE YOUR HEART RATE LEVEL?

The heart rate monitor records your data locally and presents it based on the mode and time of detection once your heart rate has been measured. 

• The standard for evaluating heart rate may vary depending on the circumstances. When assessing your heart rate, we adhere to the American Heart Association's recommended range of 60 to 100 beats per minute for an adult's resting heart rate. 

• Based on the evaluation criteria for heart rate in different scenarios, we will offer you some recommendations. However, it is important to note that the information provided is a general guideline and applies only to common conditions. Factors such as gender, physical fitness level, organ health, and individual variations can differ significantly. If you decide to follow the suggested training and adjustment techniques, please be mindful of the potential risks and consult with a healthcare professional before initiating any new activities. 

We strive to offer you informative guidance by gathering information from diverse sources and consulting with medical professionals to promote your well-being. Our aim is to provide you with reliable and helpful references to support your health.
