The iPhone Duo may already have its first killer app: a virtual Walkman

Bhargava initially built the app and demoed it at the Bitrig hackathon this weekend, where it won second place. Bitrig offers software that lets developers use AI to build native apps using Apple’s Swift programming language.

After the developer posted about the Duo-Man on X, it quickly attracted attention, topping 1.8 million views and nearly 10,000 likes. That attention has inspired Bhargava to take what was initially just a fun hackathon project and turn it into a real app.

When it arrives, the app will support Apple Music and local files and will even include a feature that would let you use your Apple Pencil to “roll” the cassette loop, we’re told. On X, Bhargava also said he plans to make the fast-forward and rewind experiences similar to the original Walkman. Spotify support may be added further down the road.

This is not Bhargava’s first app. The indie developer has published a dictionary and vocab builder, LookUp; a movie recommendations app, Movie Buzz; a time zone utility; and others.
