one sec alternatives for people who want content filtering

one sec adds a pause before apps open. The research is solid — Max Planck Institute found a 57% reduction in app opens. But the pause ends. The app opens. Reels are still there.

If your problem is what you find inside social media, not the opening itself, these are the alternatives worth looking at.

To be direct: one sec is excellent at what it does. 100,000+ five-star reviews. Research from the Max Planck Institute backing a 57% reduction in app opens. Works with any app via iOS Shortcuts. Free for one app. Available on Android.

If your main problem is the compulsive, automatic picking-up of the phone and opening apps without thinking — one sec is the right tool. It interrupts the habit loop before it begins.

The gap: once you complete the pause and the app opens, the full app is there. Reels, Shorts, the For You feed, everything. one sec changes when and how often you go in — not what you find when you do.

02
UNDOOMED Content filter, free tier

UNDOOMED is an in-app filtered browser for iOS and Android. Same content-filtering approach as Dull — removes Reels, Shorts, algorithmic feeds. Supports 6 platforms (adding Reddit and LinkedIn vs Dull's 4). Has a free tier. Pro plan $17.99/year.

No grayscale, no quiet hours, no friction gates, no commitment delay. Uses wellness-oriented framing ("Clarity Score").

Free (limited) $17.99/yr (Pro) $29.99 lifetime

Best for: one sec users switching to content filtering who want a free tier to try first, need Reddit or LinkedIn, or are on Android.

03
Opal Hard blocker

Opal takes the opposite approach to one sec: instead of a pause, it installs a hard block. When a session is running, the app cannot be opened at all. Deep Focus is unbypassable. 4 million+ users. $99.99/year.

Like one sec, Opal does not filter content — it controls access. When the block ends, the Reels are still there. Opal is for users who want a complete stop, not a filter.

Free (limited) $99.99/yr

Best for: one sec users who want something harder than a pause — a complete block during certain windows.

Problem 1 Compulsive opening

You pick up your phone automatically. Instagram is open before you decided to go there. The behavior is reflexive, not deliberate.

→ one sec

Many people have both problems. Using one sec and Dull together costs $29.98/year ($14.99 each) and handles both stages.

Does Dull add a pause like one sec does?
Dull has friction gates — a small challenge you complete before opening any platform. This is similar in intent to one sec's pause but different in implementation. It is optional and configurable.
Can I use one sec and Dull at the same time?
Yes. It is a common combination. one sec intercepts the impulsive reach for the phone. Dull handles the content once you decide to actually use social media. Combined annual cost: $29.98.
Is Dull on Android?
No. Dull is iOS only. UNDOOMED is the closest Android-compatible alternative with the same content-filtering approach.
Does Dull work with the regular Instagram app?
Dull replaces the Instagram app on your home screen. It opens the real Instagram mobile site in a filtered browser — you sign in with your actual Instagram account. Your DMs, posts, and followed accounts are all there. Reels are not.

Instagram without Reels. YouTube without Shorts.

The part that kept you there for 40 minutes. Gone.
