💡 Inspiration

Creating short-form videos often requires complex, heavy desktop tools or slow cloud-based mobile apps. We wanted to build a super-fast, responsive iOS video editor that respects user privacy while enabling effortless auto-captioning and professional-looking layered effects directly on iPhone.

🎬 What LayerClip Does

LayerClip is a native iOS video editing app optimized for speed and creative flexibility:

• Instant On-Device Auto-Captioning: Speech-to-text processing runs 100% locally on the device using Apple’s speech frameworks. No cloud uploads, zero wait time, and complete privacy.
• Native Multi-Layer Editing: Built directly with UIKit for buttery-smooth timeline navigation and real-time previews without frame drops.
• High-Res 4K Export: Deliver crisp, watermark-free videos ready for TikTok, Instagram Reels, and YouTube Shorts.

💰 RevenueCat Integration & Business Model

LayerClip integrates the RevenueCat iOS SDK to manage in-app purchases and subscriptions seamlessly:

• Monthly Subscription ($2.99 / mo): Flexible access for ongoing creators.
• Annual Subscription ($24.99 / yr): Features an introductory 7-Day Free Trial so users (and judges!) can experience Pro features risk-free.
