Screen Limiter vs one sec
Last updated November 2026
These solve opposite halves of the same problem. one sec interrupts the moment before an app opens — the tap you never consciously decided to make. Screen Limiter does nothing at the door and instead rations the minutes once you are inside. If you are choosing between them, the question is which half keeps failing.
What one sec does
- A breathing pause before the app. You open Instagram, a short animation asks you to wait, and only then does the feed appear. It is built with Shortcuts automations rather than a shield, so it interrupts rather than blocks.
- Evidence. one sec is the only app in this category with a peer-reviewed study behind it, and it reports a substantial drop in app openings.
- Re-intervention. If you do fall into a session, it can eject you after a set time and make you go through the pause again.
- Cheap to try. Free for one app, with a modest Pro upgrade.
What Screen Limiter does
- A budget, not a pause. Five minutes an hour (or another window) that blocks the app when spent and comes back on its own.
- Nothing at the door. Opening the app is normal until the allowance runs out. Screen Limiter does not try to interrupt the decision; it limits the consequence.
- Strictness you choose. Easy lets you wave the block away, Normal allows five stops a day, Hard allows one with an eight-second hold.
- No account and no analytics. Nothing leaves the phone.
| Screen Limiter | one sec | |
|---|---|---|
| Intervention point | After the minutes are spent | Before the app opens |
| Allowance | 5–30 min per 30 / 60 / 120 min window | None — a pause per open |
| Mechanism | System shield (Screen Time frameworks) | Shortcuts automation pause, plus optional block sessions |
| Account | None | None by default |
| Price | Free (payments off) | Free for one app + Pro |
From one sec's App Store listing and FAQ, November 2026.
Which problem do you have?
- "I pick up the phone and I am in the app before I decide to be." That is the reflex. one sec is the better tool, and no budget will fix it, because the budget only matters after the app is already open.
- "I decide to check one thing and surface forty minutes later." That is a long sit. A budget with a hard stop at the end is the better tool, because a pause at the door does nothing once you are through it.
- Both. They stack without fighting: one sec interrupts the open, Screen Limiter caps the session. Some people run both.
Where Screen Limiter is the weaker app. If your habit is opening apps dozens of times a day for seconds at a time, an allowance barely registers — you may never reach the limit. Screen Limiter counts minutes, not pickups, and it has nothing to say about the reflex itself.
FAQ
Does one sec block apps?
Its primary mechanic is a pause before opening, driven by a Shortcuts automation. It also offers block sessions and a re-intervention timer. It does not ration minutes the way a budget app does.
Can Screen Limiter add a pause before opening?
No. Screen Limiter has no pre-open interruption; the first change you notice is the shield, after the allowance is spent.
Which is better for ADHD?
Neither app should be treated as a treatment. Mechanically, a reflex habit tends to respond to a pause at the door, and a long-session habit to a budget. one sec is the app with published research behind it, which is worth weighing.
If it is the long sit, not the tap
Screen Limiter gives the app a few minutes at a time and shields it when they are gone, then hands the minutes back at the next window.
