Nuclease: COVID-19 Tracker

🕒 2 min read

Introducing Nuclease, an Android app to keep track of global COVID-19 cases with a customizable watchlist!

Keep track of COVID-19 cases with a dedicated watchlist! This app serves as an reference app to enable one to be able to keep track of the cases around the world, selecting only the location(s) of interest.

Reasons for creating

Why was this app created? There are a few reasons, which include allowing individual ability to keep track of various cases of the countries that you are only interested in (as a reference), the available time due to the partial lockdown and just another Android application project as so much has changed since I last developed an app. (For example how Android Support library is replaced with AndroidX)

Note: Please read the disclaimer before using the application, and only proceed if you accept to the disclaimer!


This app was created within a week, so only the main features would only be included in the app. Additional features may be included in future updates, stay tune!

  • Global summary: Piechart display of global cases, which is segregated based on the case type.
