 ## Dev Tool (TestFlight)
 
-The **Couchers (Dev Tool)** variant is a [development build](https://docs.expo.dev/develop/development-builds/introduction/) — essentially "Expo Go, but with our own native modules." It bundles every native dependency in the project plus the Expo dev launcher, and points at the staging backend. Devs install it once from TestFlight and load JavaScript over the air, so they never need Xcode, CocoaPods, or a local native build for day-to-day JS/TS work. The "Dev Tool" name signals it's a developer utility, not another release flavor like staging or production.

 **When a new Dev Tool build is required:** only when the set of native dependencies changes (adding/removing a native package, changing `app.config.js`, or bumping the Expo SDK). Pure JS/TS changes never need a rebuild — they load over the air.
