Health Data 1.0.1

This comprehensive yet straightforward application serves as an effective tool for recording and monitoring various health metrics and symptoms. Its user-friendly interface displays results in clear tables, concise graphs, and calendars, facilitating easy interpretation for users of all levels of health literacy.

Distinct from similar applications, this app uniquely combines the ability to log both quantitative data—such as blood test results—and subjective symptoms within a single platform. Users can customize their tracking parameters (additional features available via in-app purchase) and modify them as needed, providing flexibility tailored to individual health management needs.

Originally developed by a British family physician for his own patients, the app addresses common challenges faced when presenting symptoms that persist over weeks or months. Systematic documentation of symptom frequency, severity, and context can significantly enhance diagnostic accuracy, reducing unnecessary investigations and expediting medical decision-making. It supports chronic disease management by enabling users to monitor vital parameters such as blood glucose and blood pressure, as well as related laboratory markers like cholesterol and renal function tests. Additionally, it accommodates patients with conditions requiring regular blood test surveillance, such as gout or those on anticoagulants tracking INR levels. Many participants also utilize it as a lifestyle tool, tracking weight, BMI, and waist circumference.

The design philosophy emphasizes simplicity: users select the parameters they wish to track and proceed without unnecessary complexity. The app provides essential data representations—clear graphs and diagrams—that are often more impactful in clinical assessments than extensive statistical details.

Technical features include: - Ability to add remarks via typing or speech - Flagging of remarks within graphs for easy reference - Adjustment of past entries to correct timing - Deletion of erroneous data points - Customization of normal range values and measurement units to match laboratory standards - Alarm clock functionality with scheduled alerts - Notifications when measurements fall outside preset normal ranges - A quick-dial feature for contacting healthcare providers when certain thresholds are repeatedly exceeded - Visual distinction of abnormal values through red highlighting - Easy removal of incorrect entries from logs - Scrollable and stretchable line graphs for enhanced data visualization over time

With optional in-app purchases, users can extend functionality to: - Simultaneously record two numeric tests and two symptoms alongside blood pressure measurements - Define personalized tests and symptoms tailored to individual health conditions
