Device Use
Your agent reads the console, checks sensors, and captures frames from the camera. When the hardware doesn’t expose what Breakover needs, it adds instrumentation to the code.
Introducing Device Use and Phone Use.
Your agent doesn’t just write the code. It uses both your board and your phone, and makes sure they work together.
Start from scratch or bring firmware, an app, or both.
Works with your existing Claude or Codex subscription.
Built with Millwright.
How it works
The hardest bugs aren’t in any one piece — they’re in the connections between them. The board reports it sent a packet; the app never shows it. Breakover tests them all at once, so your agent can see where it fails.
Your firmware and your app have to find each other and keep talking. Breakover makes sure they do.
Your agent reads the console, checks sensors, and captures frames from the camera. When the hardware doesn’t expose what Breakover needs, it adds instrumentation to the code.
Your agent installs the app, launches it, taps through the interface, and captures what it sees. Works in the iPhone Simulator, or on a local iPhone.
Breakover handles the signing keys, certificates, identifiers, profiles, and App Store Connect.
Firmware updates are handled automatically. If a device doesn’t come back healthy, Breakover rolls it back.
