Rubber Duck is a pre-submission testing service for iOS apps that combines automated checks with human testers on real devices. Instead of waiting for Apple’s App Store review to flag issues, you upload your IPA file or provide your App Store link, and Rubber Duck runs a full scan in about 4 hours. The result is a clear, actionable Duck Report with video replays of every crash, layout problem, or performance bottleneck — so you can fix problems before Apple or users ever see them.
Rubber Duck downloads your live app directly from the App Store or accepts an uploaded IPA. Human testers explore every flow on real iPhones and iPads, exactly as your users would — no emulators, no scripts to write.
When a crash, broken onboarding, or missing privacy data is found, you get a detailed report with video recordings showing exactly where and how the issue occurred. Each finding includes clear steps to reproduce and fix it.
Choose a schedule that matches your release cycle: a single one-off scan, 3 scans per month, 10 scans per month with priority queue, or a daily scan with nightly regression testing. All plans include real device testing and a basic report.
If you follow the report’s recommendations and still get rejected for something Rubber Duck missed, they re-scan for free and update their detection systems. The Pre-Flight scan itself has a 0% rejection rate for issues it covers.
“Don’t wait for a rejection letter — catch issues before Apple or users reject it.”
Rubber Duck turns the typical 24–48 hour App Store review cycle into a proactive 4-hour pre-check. While manual QA can take days and often misses the specific criteria Apple enforces, Rubber Duck’s combination of automated checks and human testers on real devices targets the exact issues Apple flags most: crashes, incomplete build flows, missing privacy data, inconsistent metadata, and broken onboarding. The result is a clear, video-backed report that lets you fix problems before they ever reach Apple’s reviewers.
You’re shipping an iOS app update and want to avoid the 40% rejection rate that comes with submitting blind. Rubber Duck is especially useful if you don’t have a dedicated QA team, need results in hours instead of days, or want a cost-effective way to catch the specific issues Apple’s review team cares about most.
