About Rubber Duck
Rubber Duck is a pre-submission app-review scanner designed to help developers avoid rejections from the Apple App Store by catching common issues before submission. Developers upload their compiled app, and Rubber Duck runs automated scans followed by human QA, testing real device compatibility (including older iPhone models), verifying in-app purchase (IAP) flows, checking for missing metadata or placeholder content, detecting crashes on launch or during use, and ensuring privacy-policy and data-collection compliance. Within about four hours, users receive a detailed “Duck Report” listing every detected issue with severity ratings and exact repro steps, enabling them to fix problems before submitting to Apple. Scans are run in a secure, isolated sandbox; uploads are encrypted in transit and at rest; the compiled binary is the only thing analyzed (not source code); and builds are automatically deleted after 30 days (or sooner on request).
