Fluid Friction is a mobile app for adding pauses to social media scrolling and blocking selected short video feeds. It can switch off Instagram Reels, YouTube Shorts, TikTok’s For You feed, Snapchat Spotlight, and Facebook Reels while leaving other parts of those apps, such as messages, Stories, search, subscriptions, and selected videos, available where supported. The app adds haptic resistance to scrolling: users drag through a simulated wave, and the feed moves after passing a threshold. It also offers tools for limiting app use, including a nighttime phone lock, and provides 92 themes that change the appearance of the scrolling effect. On iPhone and iPad, supported social apps open within Fluid Friction’s browser to apply its feed controls. Fluid Friction is available for Android and iOS. The website states that the app and its friction tools are free, with no trial, advertisements, or payment card required. It also states that users can delete their data. Typical use involves choosing which feeds to block or tools to enable, then using the selected apps with the added scrolling resistance or restrictions.
