one sec Alternative · April 2026
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.
Dull is an iOS app that opens Instagram, YouTube, Facebook, and X in a filtered browser. Reels, Shorts, and algorithmic feeds are removed before the page loads — not time-gated, removed. Your DMs, the people you follow, your search history, and saved content all still work.
In addition to content filtering: grayscale mode, daily time limits per platform, quiet hours (e.g., no Instagram after 10pm), friction gates (a challenge before opening any platform), and usage tracking. On-device — no VPN, no external data.
The key difference from one sec: one sec intercepts the impulse to open an app. Dull changes what the app contains. They target different stages of the behavior. Using both is a common setup.
Best for: one sec users who want to go further — not just slow down impulsive opens, but change what social media looks like once they are inside.
Try Dull free for 7 daysUNDOOMED 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").
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.
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.
Best for: one sec users who want something harder than a pause — a complete block during certain windows.
You pick up your phone automatically. Instagram is open before you decided to go there. The behavior is reflexive, not deliberate.
→ one secYou open Instagram with a purpose — checking DMs, looking up a post. 40 minutes later you are watching Reels. The session length is the problem, not the opening.
→ DullMany people have both problems. Using one sec and Dull together costs $29.98/year ($14.99 each) and handles both stages.
