ZunoTales
Overview
ZunoTales is an AI-powered storytelling platform designed to help children learn through personalized stories, interactive experiences, and engaging educational content. The client had a clear vision but was unable to launch their iOS app due to technical and compliance challenges related to Apple's ecosystem.
Problem Statement
The client approached us when their iOS application was stuck and unable to go live on the App Store. Key challenges included In-App Purchases (IAP) not implemented correctly, no setup for auto-renewable subscriptions, repeated App Store rejections due to guideline violations, missing Sign in with Apple (a mandatory Apple requirement), and confusion with App Store Connect configuration. These issues prevented the app from being approved and published.
Native Authentication Implementation
We implemented a secure and seamless authentication system including Sign in with Apple (required for App Store compliance), Google Login integration, and email-based signup and login with a complete backend authentication flow. This ensured a smooth onboarding experience and full compliance with Apple's policies.
Subscription & In-App Purchase Setup
To simplify subscription management, we integrated RevenueCat and configured the full IAP system — including auto-renewable subscription setup, product creation in App Store Connect, pricing tiers and subscription groups, purchase validation and lifecycle management, and sandbox testing and debugging. This provided a stable and scalable monetization system ready for growth.
App Store Compliance & Submission
We resolved all technical and compliance issues by fixing rejected builds, correcting App Store configuration, and ensuring full adherence to Apple guidelines. We then handled the complete submission process including App Store listing optimization, metadata and descriptions setup, screenshot alignment, and direct communication with the Apple review team — providing continuous support until the app was approved and published.
Product Experience
ZunoTales delivers a seamless and engaging user experience with personalized story generation, AI-powered illustrations, voice narration for stories, interactive learning experiences, and a dedicated onboarding flow for parents and educators.
Results
The iOS app was successfully launched on the App Store with a fully functional subscription system and zero compliance issues after our fixes. Improved onboarding and user experience was delivered within the client's budget.
Business Impact
After launch, the client was able to start generating revenue through subscriptions, focus on content and user growth, avoid technical complexities of the Apple ecosystem, and build a scalable product for future expansion.
