Dull – An iOS app that filters out short-form content (Reels, Shorts) from social media platforms (Instagram, YouTube, Facebook, X)

Dull addresses a significant user pain point: the addictive nature of short-form content on major social media platforms. This product targets individuals seeking to reclaim control over their digital consumption without abandoning essential platform functionalities like direct messaging. The technical approach, relying on CSS/JS injection and MutationObserver, highlights the inherent challenge of maintaining such a solution against constantly evolving platform DOMs. This 'cat-and-mouse' dynamic represents a substantial operational overhead. While not a B2B SaaS, it reflects a broader trend of users seeking tools to mitigate the negative impacts of platform design. The market implication is a niche but potentially high-demand consumer utility, demonstrating a clear need for user-centric control over content feeds, a need that platforms themselves are unlikely to address.
