Hey Product Hunt! 👋 After building desktop video editing tools with Quick Sub 2, I wanted to bring that same precision overlay editing directly to mobile — without compromising on control or performance. Most mobile video editors either hide your elements behind clumsy templates or lack true frame-accurate timing. That’s why I built Quick Sub Mobile — a native, high-performance iOS app built entirely in SwiftUI that gives creators desktop-class overlay precision right on their iPhone or iPad.
🎨 What makes Quick Sub Mobile special:
・ Resizable Precision Timeline: Enjoy frame-accurate control over exactly when captions, shapes, or icons appear and disappear.
・ 4 Versatile Layer Types: Combine professional text captions, geometric shapes (circles & rectangles), and thousands of native SF Symbols to polish your content.
・ Built for Creators & Experimentation: Includes a full, robust Undo/Redo system so you can iterate freely, plus full project management to work across multiple videos seamlessly.
・ Pure Native SwiftUI Performance: Fast, fluid, and optimized specifically for touch-first workflows in the iOS ecosystem.
Whether you're adding crisp subtitles, highlighting key details with shapes, or dropping in SF Symbol icons, Quick Sub Mobile is built to make precision overlay editing simple and fast.
I’d love to hear your thoughts, feedback, or feature ideas. Thanks for checking it out! 🙏
