Smartphones can be used as tools for primary self-diagnostics.

Smartphones can become an important diagnostic and self-diagnostic tool, including through improvements to built-in cameras and the development of new apps.
As the price of a smartphone decreases and its capabilities improve, it becomes a valuable tool in diagnosing a growing number of diseases and illnesses around the world.

The main advantage of the smartphone is that it has huge computing power, high screen resolution, excellent cameras, and, most importantly, it is connected and available worldwide.

The ability to record data at the point of care, take pictures that can be analyzed with AI or by experts who cannot be everywhere at the same time, increases the ability to implement universal health care across the entire spectrum of health care professions.

Smartphones have great potential in screening patients and diagnosing dangerous conditions:

Eyesight :
The App can simulate what the world looks like for a person with poor eyesight. A phone camera can also mimic what the world looks like for the test person, helping parents clearly understand why their child may need treatment.

The lungs:
For example, a microphone can be used to diagnose asthma or other lung diseases.

Blood:
A camera flash can be used to determine hemoglobin levels in the blood.

Osteoporosis:
Smartphones are also available to diagnose osteoporosis, an age-related decrease in bone density. For example, you can use a phone's motion sensor to detect vibrations created by the bones. If the density of the bones drops, the frequency of oscillation will change and the sensor will lock the bone.

Urine:
AssayMe is a personal Wellness & Health Assistant that enables patients to monitor the health and prevent medical problems through a simple, at-home, self-administered urine test, as well it`s a comprehensive tool for Telehealth.

The examples show that smartphones can be used as tools for primary self-diagnostics.

In addition to direct diagnosis, smartphones can serve as monitoring tools for people with chronic diseases: to remind about taking medication, regulate the physical activity, measure some important indications of the body. This will reduce the cost of medical care, as patients will not have to go to medical staff to make simple measurements all the time.

Today's smartphones have approximately the same computing power as some medical devices. Internet and cloud technology support provides smartphones with access to an extensive database that also assists in diagnosis. This means that a mobile device can become a serious assistant to the doctor and quickly identify certain patient conditions.

As a personal medical diagnostician, a smartphone is in the near future. Mobile technologies will significantly improve people's lives with chronic diseases, as well as improve the diagnosis of some dangerous conditions.
