V5.0 Release Notes


The “Pandemic SelfDefense” (abbr. as PSD) version 5.0 is a brand new release. The app has been renamed “Pandemic SelfDefense” because it’s development is based on Google Flutter technology; an open-source UI software development kit. Flutter has a plugin system to communicate with Android and iOS for non-UI tasks. In other words, the Pandemic SelfDefense has great potential to be expanded and support iPhone users. In this 5.0 release, we have updated the following features:

  • The app has been enhanced for consistency, availability, high reliability.
  • The response rate to geo-location request has been optimized to be in near real-time. 
  • The geo-locator can respond to user’s location change request in near real-time. The geo-locator pin on the world’s map allows instant user access to the detail information of the vaccination/test centers published by the U.S. Centers for Disease Control and Prevention (CDC).
  • Self symptom assessment function is more interactive and user-friendly.
  • User’s historical records of the social distance nudges and social pods is more reliably displayed.
  • Bluetooth activation checkand permission checkon android device have been enabled.

  • The app has been enhanced with optimization of the operational runtime time. The app response rate and data transfer rate (to obtain the nearby test center locations) has been significantly improved with robustness and accuracy. The identification of the nearby test centers now returns very reliable results.

V2.0 Release Notes


The iSensor Lab is pleased to announce its first public release (version 2.0) of the android mobile application; CV19 SelfDefense, developed in Android Studio. The CV19 SelfDefense mobile app is a research project funded by Florida State University Collaborative Collision Seed Grants (CC-045704, 5/11/2020 – 8/18/2020 and CC-046280, 9/1/2021-6/30/2022). Interested users may download this version to an android phone, register an account with the iSensor server, and login to their personal account with a dashboard of features and tools to begin utilizing the services provided that help users to defend themselves during the Coronavirus pandemic. Dashboard features include the following:

  • News Updates: Users will receive an RSS feed of recent postings from the Google News, Centers for Disease Control and Prevention (CDC) and Department of Health and Human Services (HHS).
  • Vaccination Center Locator: Users can identify nearby test centers based on user’s current geo-location. The app has adopted CDC vaccination center database and has now 56,410 COVID vaccination/test centers across 50 states and Puerto Rico in the current database.
  • Symptoms Checker: Users can assess development of their own symptoms based on CDC guidelines.
  • Social Distance ‘Nudge’: Adopting Bluetooth technology, users can scan the surrounding areas – via automated or manual scan – to get “nudges” (phone vibration and notification of other nearby devices). This feature also helps users to identify and remember contacts and safe devices of close interactions, and thus create a ‘safe social pod‘ when necessary. Automated scanning for social distance nudge occurs every minute.
  • Quarantine Monitor: This feature helps users to monitor and keep track of personal whereabouts during a self-quarantine period of 14 days. Multiple home locations – where users feel safe – can be added to assist users’ memory. A summary report will be generated at the end of the quarantine period.
  • Account Profile: Users can change passwords, login and logout of the app from the negation drawer by pulling from the left-hand side of the app.
  • Survey: User feedback survey is updated accordingly to the studies approved by FSU Office for Human Subjects Protection with IRB protocol STUDY00001550, MOD00000679, STUDY00001612 and MOD00001103.

We hope this tool can help users not only receive up-to-date information from the healthcare authorities, but also defend their personal health against Coronavirus and its sub-variants. Click here for the tutorial. We welcome your feedback.
