By using our application, you will be able to:

  • See your weekly progress in terms of number of voidings.
  • Track and check your symptoms by filling in a bladder diary.
  • Distract your mind whenever you feel the urge to urinate.
  • Get more information about the treatment and the condition.
  • Locate the nearest favourite location that might offer free toilet access.

Study Structure and Data Collection

The study lasts for minimum 4 weeks but ideally 6 weeks, during which participants are asked to interact with the application freely as with any other app on their phone. Our only request is to fill in three questionnaires and a bladder diary. The bladder diary is required to be filled in for three consecutive days during the first, third and last week of the study. Notifications will be sent throughout the study to indicate when you should complete the questionnaires. 

Ideally, the study should start on a morning.

What we collect:

The application collects the following data: WIFI networks, environmental sensors (light, magnetic field, accelerometer and microphone) data, app usage (the number of accesses per feature and duration) and health data (Overactive Bladder symptoms). The data collected and provided will be automatically uploaded to a server. We collect only basic demographic data such as age, gender, employment status, level of education, family status and level of technical ability. We do not provide any participant number but we collect your IMEI (International Mobile station Equipment Identity) number to link the sensor data collected with the app usage. Optionally, participants will be asked to provide an email address to receive a £20 gift voucher, if they complete the minimum 4 weeks.

What we do not collect:
We do not ask any additional personal information such as name and even though we collect the IMEI number, we will not use it to track back any person. The application does not collect any other personal information such as photos, messages, contacts, etc. 

We also offer the possibility of taking part in the study without offering us any information about yourself (no need to complete the questionnaires). We will still collect all the other data mentioned above (WiFi, sensors, app usage and bladder diary) and unfortunately, will not be able to offer you the £20 voucher as a Thank you. Regardless of your preference, please click on this LINK and follow the instructions in order to install the application. If you wish to uninstall the application at any point they are free to do so without any consequences and we will delete any material that involves their contribution.

We are also more than happy to assit you if you are not sure how to install the application. Please note that only recent Android Operating System smartphones (e.g., Samsung, Sony Xperia, LG, Huawei) not older than three years are compatible for this study.
