Solo dev's open-source Android agent Mika hits 7,900 stars in 11 days

A solo developer built Mika, a free, open-source AI assistant for Android. Given a one-sentence instruction, it reads the screen and taps, types and scrolls like a human, so it works in any app with any plugged-in model—unlike Siri, which is limited to apps with developer support.

It runs on a hidden background screen so you can keep using your phone, keeps all data on-device with no server, and hands logins, verification codes and payments back to the user—e.g., it finds a charger under $30 with 4.5 stars, adds it to cart, and stops before checkout. The repo gained 7,900 GitHub stars in 11 days.
