Spool vs Dull: Both apps let you use social media through a filtered browser without Reels and Shorts. Dull offers a wider control toolkit across five platforms; Spool combines filters across Instagram, YouTube, X, and Snapchat with a 5-second voice check-in, AI trigger analysis, and friend accountability. Choose Dull for browser customization; Spool for filtering plus behavior change.
Dull and Spool now overlap more than most screen-time comparisons. Neither requires you to choose between the full native app and no access at all. Both let you open social platforms through an in-app browser and remove the features that start an unintended scroll. The difference is what each app builds around that filtered experience.

The core similarity: filter the surface, not the whole app
Both products recognize that "block Instagram" is often the wrong job. The person may want Instagram for one intentional task but not want Reels, Stories, Explore, or suggested content waiting beside it. Dull and Spool solve that by loading the web platform inside a controlled browser and hiding selected surfaces.
That makes both meaningfully different from traditional app blockers. A blocker controls whether the app opens. A filtered browser controls what is present after it opens.
Where Dull is stronger
Dull is the more mature filtering toolkit. Its current site documents five supported platforms, platform-by-platform removed and kept lists, daily limits, quiet hours, friction gates, grayscale, on-device usage statistics, a 24-hour commitment delay, and a PIN. It also publishes precise technical explanations of how its browser filters work.
If your goal is to design several different versions of social media—strict during work, looser on weekends, grayscale at night—Dull's control surface is the more expansive one.
Where Spool is different
Spool treats content filtering as one layer, not the entire intervention. Its second layer is a 5-second voice check-in before a selected native app opens. You say why you are reaching for the app; Spool then turns those statements into a record of triggers and patterns.
This matters when removing the feed does not remove the urge. A filtered Instagram can prevent a Reels spiral, but it cannot explain why you tried to open Instagram 30 times while avoiding a deadline. Spool's spoken data is built for that question.
Instagram DMs reveal the product philosophy
Dull preserves Instagram DMs by default because it defines messaging as utility. Spool lets the user hide DMs too, because a communication surface can still be a trigger for some people. Neither choice is universally right. Dull makes a stronger default judgment about what should stay; Spool gives the user a separate switch.
Who should choose which?
Choose Dull if: you want extensive browser customization, five supported platforms, grayscale, time limits, commitment controls, and detailed local usage stats.
Choose Spool if: you want Instagram, YouTube, X, and Snapchat filters plus an active voice intervention, AI analysis of your stated reasons, and friend accountability.
Either can be the right answer: the deciding question is whether your main problem is the content surface itself or the emotional habit that keeps sending you back. Dull goes deeper on the surface. Spool works on both.
Frequently asked questions
Can Spool and Dull both remove Instagram Reels?
Yes. Both provide a filtered Instagram web experience rather than modifying the native Instagram app.
Does Dull support Snapchat?
Dull's current platform page says Snapchat is not supported in its present version. Spool Focus Web can hide Spotlight, Stories, and Discover from its Snapchat web experience.
Is Dull or Spool better for understanding why I scroll?
Spool. Dull shows behavioral usage data; Spool captures the spoken reason at the moment of the app open and analyzes those reasons for recurring triggers.
