India said it will publicly release the source code of its contact tracing app, Aarogya Setu, in a relief to privacy and security experts who have been advocating for this ever since the app launched in early April. 

Ajay Prakash Sawhney, secretary in the ministry of electronics and information technology, made the announcement on Tuesday, slating it as “opening the heart” of Aarogya Setu’s Android app, which has amassed over 115 million users in fewer than 60 days, to allow engineers to inspect and tinker with the code.
