Catch App Store rejection issues before Apple does.
Rubber Duck scans your iOS app before you submit it to the App Store. We combine automated checks with human testers on real devices to catch the issues Apple flags the most: crashes, incomplete build flows, missing privacy data, inconsistent metadata, broken onboarding, and more. Upload your IPA → we test → you get a clear actionable Duck Report.
Hi everyone! I'm the maker of Rubber Duck. After shipping iOS apps, I realized how unpredictable App Store review can be. Even great apps get rejected for:
Missing metadata
Small UI issues
Broken flows on certain iPhone models
Forgotten privacy entries
One-off crashes Apple found
Each rejection set the launch back days. So I built Rubber Duck to be the “review before the review.” It combines automated checks with human testers using real iPhones like an App Store reviewer, but faster and kinder.
Excited to hear what you think and how we can make this even more useful!
