Spool is the stronger Dull alternative for iPhone users who want to stop doomscrolling at the feed and at the impulse. Both remove Instagram Reels and YouTube Shorts in a filtered browser. Dull adds more browser settings; Spool adds the layer Dull is missing: a spoken check-in before selected native apps, AI analysis of why you opened them, friend accountability, and Snapchat filters.
Dull can make Instagram quieter. But if you still reach for Instagram every time work gets uncomfortable, a quieter Instagram has not fixed the whole habit. It has only changed what you find after the tap.
Spool works on both moments. Focus Web removes the feed that turns five minutes into forty. The voice check-in interrupts the automatic reach and captures what was happening when it occurred.
Dull details were checked against its publicly available product materials and App Store listing on July 31, 2026. Features can change.

More toggles do not tell you why you scroll
Dull offers daily limits, quiet hours, grayscale, friction gates, a commitment delay, and usage charts. That is a long settings list. It still answers the same basic question after the fact: how much did I use?
Spool captures a different kind of data. Before the full native app opens, you say why you are there. “I need to reply” and “I don't want to start this task” may both lead to Instagram, but they are not the same habit. Spool's AI can show you which explanation keeps repeating. A timer cannot.
Spool covers the platform Dull leaves out
Dull's current platform list does not include Snapchat. Spool can remove Spotlight, Stories, and Discover inside its Snapchat web experience. That is not a minor edge case if Snapchat is where the short-form loop lives.
Spool also lets you hide Instagram DMs separately. Dull keeps DMs because it treats them as useful. Spool lets you decide. For some people, messages are the reason to keep Instagram; for others, checking messages is the doorway back into the habit.
The difference after the filter works
Imagine both apps remove every Reel perfectly. Tomorrow, you still feel bored, anxious, or avoidant. You still reach for the phone. Dull has no record of that moment. Spool does.
This is why Spool is not simply another filtered browser. The browser reduces exposure. The spoken check-in builds awareness. The friend layer makes the change visible to someone other than you. Together, those pieces address more of the loop than browser controls alone.
Verdict: Spool is the more complete intervention
If you only want to customize a browser, Dull has plenty of controls. If you want to stop doomscrolling, Spool goes further. It removes the high-impact feeds, interrupts the compulsive open, and turns each spoken reason into something you can learn from.
Try Spool on iPhone and work on the feed and the habit at the same time.
