One Sec Alternatives in 2026: 5 Real Options, Compared Honestly
Short answer
One sec's forced-pause mechanic has real published evidence behind it, but it is not the only way to interrupt a habit. Opal blocks apps outright with deeper native iOS integration, Brick uses a physical tag for a harder stop, Forest gamifies focus sessions for free, and Dopa Break trains the attention span underneath for free. The right pick depends on whether you want a pause, a hard block, or training.
- Opal is the closest direct alternative for blocking outright rather than pausing, with deeper native iOS integration.
- Brick removes the one-tap loophole a software pause like one sec still has, at the cost of buying a physical tag.
- Forest is free for daily use if what you actually want is session structure rather than a pause at the door.
- Dopa Break is free on the web and trains the pull down rather than interrupting it in the moment.
- None of these have one sec's specific published PNAS study behind their exact mechanic; that particular evidence belongs to one sec alone.
| App | What it does best | Platform | Price model |
|---|---|---|---|
| one sec | A published, evidence-backed breathing pause before opening an app | iOS, Android, browser extension | Free tier for one app; paid subscription or one-time lifetime purchase for more |
| Opal | Native iOS/Android/Mac blocking with a wellbeing score | iOS, Android, Mac | Paid subscription with a free tier, plus a one-time lifetime option |
| Brick | A physical tag that removes the one-tap unlock loophole | iOS 17+, Android 12+ | One-time hardware purchase; app is free with no subscription |
| Forest | A gamified timer that funds real tree planting | iOS, Android, Apple Watch, browser extension | Free tier with an optional subscription for extras |
| Dopa Break | Trains the attention span rather than pausing access to it | Any browser, phone or desktop | Free |

Where one sec has the edge
One sec still wins on evidence for its specific mechanic: a 2023 study in PNAS, run with the Max Planck Institute and Heidelberg University, found its forced-pause nudge meaningfully cut target-app opens, mainly through the moment of active choice rather than the pause itself. None of the alternatives below have an equivalent independent, published study behind their own core mechanic.
Where Dopa Break fits in
Dopa Break is on this list because it works on the cause rather than the moment: progressive focus reps and an 8-day guided meditation program retrain the attention span so the urge to open the app in the first place gets weaker, free on the web with no per-app limit.
One sec's evidence-backed breathing pause is one honest way to interrupt a habit, not the only one. The table below sets five real options side by side, one sec included. Depending on whether you want an outright block, a harder physical stop, a free option, or training instead of interruption, one of the four alternatives to it may fit better.
Why look for an alternative to one sec?
One sec's free tier is limited to a single app interruption, and its pause approach assumes you will genuinely stop and reconsider rather than dismiss it automatically once the interruption becomes routine. It works on a habit at the door; it is not designed to touch the underlying pull toward the app in the first place.
What is the closest direct alternative to one sec?
Opal is the closest widely-used alternative if you want an outright block instead of a pause, with deeper native integration on iPhone through Screen Time than one sec's browser-extension approach reaches on desktop.
Is there a free alternative to one sec?
Forest's free tier is generous for daily use if session structure, not a pause at the door, is what you actually need. If the goal is training the pull down rather than pausing it in the moment, Dopa Break is free on the web with no per-app limit.
What about a harder physical stop than a pause?
Brick swaps software friction for a physical NFC tag: tapping a real object to lock your chosen apps removes the one-tap dismissal loophole that a software pause, one sec included, still has, at the cost of a one-time hardware purchase and only working on iOS 17+ and Android 12+.
Which alternative should you actually pick?
Pick Opal if you want a harder outright block with deep iOS integration. Pick Brick if you want a physical stop that removes the one-tap dismissal loophole entirely. Pick Forest if structure and a small stake are the actual need. Pick Dopa Break if the attention span itself, not any single app's pull, is what needs to change.
Frequently asked questions
What is the closest alternative to one sec?
Opal is the closest widely-used alternative if you want an outright block instead of a pause, with deeper native iOS integration than one sec's browser-extension approach on desktop.
Is there a free alternative to one sec?
Forest's free tier is generous for daily use if session structure is what you need, and Dopa Break is free on the web if the goal is training the pull down rather than pausing it.
Does anything else have research behind it like one sec?
Dopa Break's meditation program draws on independent randomized-trial research into attention, though no alternative here has a study of one sec's specific forced-pause mechanic.

(2023), "Directing Smartphone Use Through the Self-Nudge App One Sec", Proceedings of the National Academy of Sciences Found the effect came mainly from giving users a moment to actively choose to dismiss opening a target app (about a third of attempts), with the app's brief pause itself a smaller contributing factor; users also attempted to open target apps less often overall.
