I found Claude app's hidden internal settings
A developer unpacked the Claude Android app to investigate its engineering, as Anthropic has not publicly shared much about it. They discovered a boolean named "is_ant" and a hidden internal settings menu. This menu is reportedly used by Anthropic engineers for testing, debugging, and configuring the app during its development phase. A full report on these findings is available.

Anthropic has written a lot about Claude and Claude Code, but there isn't much about the engineering behind the Android app. So I decided to unpack it and take a look myself.
One of the first things that stood out to me was a boolean called is_ant.
Following that, I found a hidden internal settings menu used by Anthropic engineers to test, debug, and configure the app during development.
