# Aimless Scrolling

> Understand the feed. Take back your attention.

Aimless Scrolling is a free, ad-free reference operated by ai51 UG (haftungsbeschraenkt). It explains, in plain language, how social media apps engineer aimless scrolling, doomscrolling, and zombie scrolling — the For You feed, autoplay, infinite scroll, variable rewards — and gives sourced, practical ways to understand the habit and scroll less. Health and psychology claims cite primary research; anything time-sensitive states its date.

- [TikTok Settings That Slow the Feed Down](https://aimlessscrolling.com/how-tiktok-keeps-you-scrolling/tiktok-settings-that-slow-the-feed/): Use TikTok's own settings to slow the feed: daily screen-time limits, break reminders, muted notifications, and "not interested" to reshape recommendations.
- [Why TikTok Feels Faster Than Everything Else](https://aimlessscrolling.com/how-tiktok-keeps-you-scrolling/why-tiktok-feels-faster-than-other-apps/): TikTok feels faster because short clips, instant autoplay, single-item focus, and quick feedback shrink the gap between wanting and getting a reward.

- [Notifications and the Pull to Open the App](https://aimlessscrolling.com/how-instagram-reels-keeps-you-scrolling/instagram-notifications-and-the-pull-to-open/): Likes, comments, tags, and bundled "suggested" alerts are external triggers that restart the scroll.
