Brillio | Kids Video, Games and Audio Learning App - SwiftUI

Brillio – Kids Video, Games and Audio Learning App for iOS

Brillio is a complete, App Store-ready kids entertainment and learning platform. It streams videos, songs, bedtime stories and audio books from a Firebase-powered content library, plays them in a kid-friendly player, downloads content for offline playback, and ships with three fully playable mini-games (spelling, arcade and math). The paid part of the library is unlocked with an auto-renewable premium subscription, and every purchase or internet action is protected by a 4-digit parental lock code.

Demo Instructions

• There is NO login and NO demo account – the app signs in anonymously on first launch.
• On first launch the app asks you to create a 4-digit parental code. Enter any 4 digits twice to reach the content.
• Configuration is required before the content grid fills up: the app loads its videos, songs, stories and books from YOUR OWN Firebase project (free tier works). Create a Firebase project, enable Anonymous Auth + Firestore + RemoteConfig, and drop the downloaded GoogleService-Info.plist into the project. Full step-by-step instructions with the exact Firestore collection structure are in documentation.html (section: Firebase Setup).
• The premium subscription button requires a configured In-App Purchase product in App Store Connect (free to set up with an Apple Developer account). Instructions in documentation.html (section: Subscription Setup). Without it, browsing and all free features still work.
• Everything else – games, downloads screen, settings, parental lock – works out of the box.

Development Disclosure

Portions of this template’s source code were developed with AI-assisted tools. All code has been reviewed, tested and verified by the author before publication.

Important Cost Disclosures

• Firebase (Auth, Firestore, RemoteConfig, Analytics): the free Spark plan covers modest usage, but exceeding Firebase’s free-tier quotas requires upgrading to the Blaze pay-as-you-go plan, and Google will charge you real money for the overage. Monitor usage and set budget alerts in the Google Cloud console. Pricing: firebase.google.com/pricing
• PostHog (analytics): integrated for product analytics; PostHog’s free tier is limited by monthly event volume and exceeding it incurs per-event charges. Remove the SDK or self-host if you don’t want it. Pricing: posthog.com/pricing
• In-App Purchases and subscriptions: creating, testing and shipping the auto-renewable subscription requires an active Apple Developer Program membership, which costs USD $99 per year.

Please Note

This is a source code template, not a compiled app. Basic Xcode knowledge is required to build and customize it. Content is served from your own Firebase project and you add your own kid-safe media – no copyrighted content is bundled. The subscription requires a configured In-App Purchase product in App Store Connect.
