Why we built mobile-first when everyone else chose web
Real device preview, QR testing, and a path to App Store — that's Saturn's bet.
Most AI app builders optimize for web dashboards. We started with Expo and React Native because the output people actually want is on their phone.
Saturn runs a real dev server in the cloud, streams logs, and gives you a QR code to test on device in seconds — not a iframe pretending to be mobile.
That same pipeline extends to App Store builds: .ipa and .aab export when you're ready to ship.
