Put the build on your phone the way you already do. Your coding agent taps through it and sends back what broke, with a screenshot.
UI test tools need a signed runner on the device, developer mode and a rebuild when the signature expires. Zeptap works from the screen and a Bluetooth pointer instead, so it drives any build: TestFlight, App Store or one you just ran from Xcode.
Push notifications, sign-in codes that arrive by SMS or email, permission prompts, the share sheet, widgets, and hand-offs to Settings, Mail or Messages and back. Your agent can leave your app to fetch the code and come back to finish signing in.
Claude Code changes the code, you rebuild, and it checks the result on the phone in the same session. Every action returns a screenshot once the screen settles, and on-device text recognition lets it confirm a label is really there.
Zeptap sees what's on the screen: screenshots and the text in them. It doesn't read your app's view hierarchy. For large regression suites across dozens of devices in CI, a device farm is still the better tool. Zeptap is for checking your real flows on your real phone while you build.
