Two tools. Use one or both.
Loosen a filter? That takes 24 hours.
If you try to turn off a filter or reduce a time limit, Dull queues the change for 24 hours instead of applying it now. You can cancel the pending change any time during that window. If you still want it after a day, it goes through. If it was an impulse, it doesn't.
A lock only your clearer self can open
Set a 4-digit PIN and Dull's settings go behind a gate. Every platform still works — you can open Instagram, use YouTube, everything. The PIN only protects settings. You can still use the apps. You just can't change your own rules on a whim. Removing the PIN has a 48-hour cooldown.
No competitor has this
The problem it solves
Every screen time tool has a bypass. This one too.
You can delete Dull. You can open Instagram in Safari. You can do a lot of things. Commitment lock doesn't eliminate all of that. What it eliminates is the easy in-the-moment reversal — the one that happens at 11pm when you're bored and tired and your filters feel annoying. The delay makes you wait until tomorrow. Usually the impulse is gone by then.
You set the PIN for yourself — not because someone told you to
This isn't a parental control. Nobody else sets the PIN, nobody else holds it, nobody else decides when you can change your settings. It's a message from your clear-headed self to your bad-moment self. You decide when to use it, how strict to make it, and whether to remove it. Removal just has a 48-hour cooldown so it can't be undone impulsively.
