Overview
Rubber Duck is a specialized iOS app testing service that scans your app before you submit it to the App Store. It combines automated checks with human testers on real devices to catch common rejection issues like crashes, incomplete build flows, missing privacy data, inconsistent metadata, and broken onboarding. You upload your IPA or provide an App Store link, and within about 4 hours you receive a detailed Duck Report with video replays and actionable steps.
Hero Widget is a free, embeddable widget that displays your MRR (Monthly Recurring Revenue) and user count metrics in real-time on your website. It integrates with popular payment platforms like Stripe, Lemonsqueezy, Paddle, Gumroad, and Whop, and can be added with a simple iframe code. It's designed to build trust with visitors by transparently showing your growth.
