About this app

BladderCare is a symptom recording app designed for participants in clinical studies related to overactive bladder and bladder cancer.

With a single button press, you can record moments of sudden urge to urinate that are difficult to hold (urinary urgency) and conveniently keep records of your urination diary and medication administration.

※ This app is a symptom recording tool for research purposes and is not a medical device intended for the diagnosis, treatment, or prevention of any disease.

※ Only participants who have been provided with a study number by the research team can use this app.

■ Key Features

[One-Touch Recording of Urgency]

· When you feel an urgent urge to urinate and it becomes difficult to hold, press the "Urgency Detected" button, and the time will be automatically saved.

· You can also record immediately upon opening the app via the home screen widget.

· Subsequently, the urination diary records whether urination occurred, the intensity of the urinary urgency (weak, moderate, severe), the presence of incontinence, and the time it took for the urinary urgency to pass. · If you are unable to write immediately, you can write it later, and you will be notified of any uncompleted urination logs.

· For urgent urinations where you were unable to press the button, you can enter them retrospectively based on what you remember.

· Depending on your study settings, a designated audio track may play during urgent urination records.

[Earbud Heart Rate Recording]

· When wearing the dedicated wireless earbuds, your heart rate from 10 seconds before pressing the urgent urination button until you select whether to urinate is saved in the record.

· Heart rate is not saved during normal use.

· You can check the earbud connection status, left and right battery levels, and today's wearing (measurement) time on the home screen.

· If the connection is poor, please follow the troubleshooting guide within the app.

[General Urinary & Medication Injection Recording]

· If you urinate without urgent urination, the time is recorded as "General Urinary."

· The time of medication injection is recorded, and the time until the first urination is managed together.

[View Records]

· You can view records saved so far by date and edit or delete details.

[Notifications]

· You can receive notifications for completing the urination log and for medication injections.

· You can set it so that notifications are not sent during nighttime hours (22:00–07:00).

■ Personal Information and Data Transmission

· Records are identified only by the study number. Directly identifiable information, such as names or contact details, is not transmitted.

· Raw signals from the earbuds' optical sensors and accelerometer are not transmitted outside the smartphone. Only the record content and heart rate data at 1-second intervals are transmitted to the study server via encrypted communication (HTTPS).

· Records that could not be transmitted due to a lack of internet connection remain on the smartphone and will be re-transmitted the next time the app is launched.

■ App Permissions

· Nearby Devices (Bluetooth): Search for and connect to earbuds

· Location: Required for searching for Bluetooth devices (Location information is not stored or transmitted)

· Notifications: Notifications for writing urination logs and medication injections

■ Precautions for Use

· If symptoms worsen or adverse reactions occur, please contact the research team or your attending medical staff immediately.

· Do not judge your health status based solely on the information recorded in the app.
