Mobile-optimized YouTube Downloader for Long Videos

The user explicitly states a pain point: existing YouTube downloaders struggle with long videos (8+ hours) and high quality (720p+) on mobile devices. This highlights a specific, underserved niche within content consumption. A SaaS offering could be a robust, mobile-first web application or a native app designed specifically to handle large video files efficiently, providing reliable downloads for long-form content like podcasts, lectures, or documentaries. Features could include background downloading, queue management, and multiple quality options. Monetization could be via a freemium model (e.g., limited video length/quality for free, premium subscription for unlimited downloads, faster speeds, and ad-free experience) or a one-time purchase for the app.
