• An ecosystem of 137 service modules: From adaptive decoding pipelines to frame-perfect animations, each piece ensures smooth and efficient performance.

• Frame Precision Decoding: Supports real-time playback of up to 9 animated cards without contention, optimized using staggered frame decoding and the Web Animations API.

AI as a Co-Creator -

While AI contributed significantly to the development of Hero Forge, every aspect, architectural design, optimization, and pixel-level polish - was human-directed. The app represents a balance, using AI as a tool for amplification while maintaining creative control and a high-quality vision.

Whether you're excited about the seamless live wallpapers, dynamic collectible experiences, or the robust tech under the hood, I'd love to hear your feedback—especially on performance and the live wallpaper functionality.

Dive into the future of mobile wallpapers with Hero Forge!

I hand-curate 1000+ AI-generated fantasy wallpapers for a free collectible card game - here's what that actually looks like

There's a misconception that AI art = press button, get result. Here's what it actually took to build Hero Forge, a collectible card game where every card is a unique 4K animated wallpaper:

The process for each card:

Write and refine the prompt — sometimes 10-20 iterations before the concept even works

Generate and re-generate — most outputs get rejected. I'm looking for specific composition, color, and mood

For animated cards: manually edit the video, adjust the loop point, re-render until the loop is seamless

Quality check everything — every single card in the app has been individually reviewed

Multiply that by 1,000+ cards across Characters, Artifacts, Pets, and Banners, with rarity tiers from Common to Legendary.

The app itself is a full collectible experience — build your collection, set any card as a live wallpaper, sync across devices with Google Drive. All free, solo-developed.

I have gotten alot of pushback about using AI Art. I get it, I'm pushing some limits here, and it can be a bit scary. Thing is, I am an artist. I have been working in game developement for a long time, both on the art and coding sides of things. I can tell you, making this app is extremely artistic, and having such an incredible tool like AI for that proper clean assitance is incredible. But let me make it clear, AI made this possible, but did not take away any of the human effort needed to make it happen. This app has been an entire year of every night griding.

Hero Forge - AI 4K Live Wallpapers

Hero Forge - Free AI 4K Live Wallpaper App for Android

Live Wallpaper Collectable Card Game!

Hey everyone! I built Hero Forge, a free collectible card game-style app that uses AI-powered 4K wallpapers and animated live wallpapers. Each and every wallpaper loops near seamlessly. I have manually edited all 1000+ animated wallpapers (and have re-rendered all of them many times over to perfection).

What makes it different:

• CCG-style collecting: Characters, Artifacts, Pets, and Banners — with rarity tiers (Common through Legendary)

• AI-generated art: Every card features unique fantasy/sci-fi artwork

• Animated live wallpapers: Set any card as a live wallpaper directly from the app

• Cloud sync via Google Drive — your collection carries across devices

• 100% free, no paywalls

Play Store: https://play.google.com/store/apps/details?id=com.heroforge.app

Custom prompt engineering — each image is carefully prompted and iterated on, not randomly generated

Curated selection — every image is re-rendered dozens of times to find the perfect result. Most generations get rejected

Video production — animations are manually edited, looped, and re-rendered multiple times to get smooth, seamless playback

Quality control — every card in the app has been individually reviewed and selected from many attempts

Take a look at the app itself beyond just the wallpapers. This is a fully-featured collectible card system with animated previews, rarity tiers, cloud sync, theme customization, multi-language support, and a ton of polish under the hood. All built by one person. The Tech Behind Hero Forge,

Hero Forge is a solo-developed app built from the ground up with React 19 + TypeScript + Vite, deployed as both a Progressive Web App (Firebase Hosting) and a native Android app via Capacitor TWA (Trusted Web Activity).

Under the Hood:

The codebase sits at ~19,700 TypeScript files across:

137 service modules (everything from adaptive timeouts to video frame extraction)

64 components with full animation systems

video decoder pipeline — plays up to 9 animated cards simultaneously without decoder contention, using per-card frame-staggered play() calls

Web Animations API integration for smooth glow wind-down effects on library cards

Frame budget scheduler and media decode queue for consistent 60fps on mid-range Android devices

Offline-first architecture with IndexedDB, service workers, and Google Drive cloud sync

11-language i18n system with type-safe translation keys,

The AI Development Part,

Yes, AI assisted in the development process too. But "vibe coding" doesn't mean "hands-off." Every architectural decision, every performance optimization, every pixel-level polish pass was human-directed. The AI is a force multiplier — the vision, quality bar, and creative direction are all mine.

Would love any feedback — especially on performance and the live wallpaper feature!
