健康管理簿 - 健康と運動の記録 is a free Android app developed by ひろん. It falls under the Lifestyle category with a subcategory of Health & Fitness. The app allows users to define custom recording items and record, display on a calendar, list, and graph their health and exercise data.

Users can define various types of recording items such as numerical values, text, selection options, start time/end time, and even photos. When recording numerical values and start/end times, the app can generate graphs based on the recorded data.

The app comes with default recording icons, including weight/height (which automatically calculates BMI), blood pressure (which automatically calculates pulse pressure and average blood pressure), body temperature, and exercise duration.

For recording start/end times, users can utilize a timer or stopwatch.

The app also provides a "One-Tap Recording" widget that allows users to quickly record data from the home screen. Additionally, there is a "Today's Schedule" widget that displays the planned activities for the day and allows for one-tap recording. When the timer or stopwatch is running, the current value is displayed on the home screen.
