Dopa Break vs One Sec: A Forced Pause or Trained Focus?
Short answer
One sec and Dopa Break work on different moments of the same habit. One sec interrupts you as you try to open a chosen app, with a breathing pause and a moment to choose. Dopa Break trains the attention span that makes you reach for that app in the first place. One sec is the faster fix for a single app; Dopa Break is the slower fix for focus itself.
- A 2023 study published in PNAS found one sec's effect came mainly from the moment of active choice to dismiss an app, not the breathing pause alone, and meaningfully cut how often people opened target apps.
- One sec interrupts a single habit at the door; Dopa Break trains the attention span behind every habit, not just the ones you have set a rule for.
- One sec's free tier covers one app interruption; a paid subscription or one-time lifetime purchase unlocks the rest. Dopa Break is free on the web with no per-app limit.
- One sec runs on iOS, Android and as a browser extension, covering phone and desktop; Dopa Break runs in any browser too, on any device.
- Pairing one sec on your worst one or two apps with daily Dopa Break training addresses both the trigger and the pull behind it.
| one sec | Dopa Break | |
|---|---|---|
| Main job | Interrupt opening a chosen app with a breathing pause | Train attention span and recover after scrolling |
| Works after uninstalling | No, the pause disappears with the app | Training effects carry over |
| Price model | Free tier limited to one app; paid subscription or one-time lifetime purchase for the rest | Free |
| Platform | iOS, Android and a browser extension (Chrome, Safari, Firefox, Edge) | Any browser, phone or desktop |
| Evidence it points to | Published 2023 PNAS study with Max Planck Institute and Heidelberg University | Meditation and implementation-intention research cited in-app |

Where one sec has the edge
One sec is genuinely better than Dopa Break at interrupting one specific habit at the exact moment it happens, and it has real published evidence behind that mechanic: a 2023 study in the Proceedings of the National Academy of Sciences, run with the Max Planck Institute and Heidelberg University, found its nudge meaningfully cut how often people opened target apps, mainly through the moment of active choice rather than the pause itself. If the job is stopping yourself opening one app fifteen times a day, one sec has both the mechanic and the study to back it.
Where Dopa Break fits in
Dopa Break is for the attention span itself, not one app: progressive daily focus reps and an 8-day guided meditation program retrain the underlying stamina so sitting with a single task stops feeling unbearable, on the web with no card required and no per-app limit like one sec's free tier.
One sec and Dopa Break both take the habit seriously, but at different points. One sec puts a breathing pause between you and a chosen app, right as you try to open it. Dopa Break trains the attention span that generates the reach for the phone in the first place, so the urge itself gets weaker over time.
What does one sec actually do?
Pick an app, and one sec inserts a short interruption before it opens: a breathing exercise, and sometimes a mirror reflection or a prompt to state why you are opening it. The point is not to block you outright but to force one real moment of active choice. It runs on iOS, Android and as a desktop browser extension across Chrome, Safari, Firefox and Edge.
What did the PNAS study on one sec actually find?
A 2023 study published in the Proceedings of the National Academy of Sciences, run in cooperation with the Max Planck Institute and Heidelberg University, found real, measured effects: people meaningfully reduced how often they opened target apps. The researchers traced most of that effect to the moment of active choice to dismiss the app rather than to the breathing pause itself, which is a more specific and more honest finding than "breathing calms you down." (One sec's own marketing separately advertises a 57% figure across its research portfolio; that number is the company's, not a figure reported in the PNAS paper itself, so it is left out here.)
What does Dopa Break do differently?
Dopa Break does not sit at the door of any one app. It trains the attention span with progressive daily focus reps and an 8-day guided meditation program, so the underlying pull toward any distracting app weakens, not just the one or two you have set an interruption for.
Should you use one sec, Dopa Break, or both?
If one or two specific apps are the whole problem, one sec's evidence-backed nudge is a strong, fast answer. If the problem generalizes (every app pulls, not just one) training the attention span behind all of them is the piece one sec cannot reach. Using both, one sec on the worst offenders and Dopa Break daily, is a common and reasonable combination.
Frequently asked questions
Does the one sec breathing pause really work?
A 2023 study published in PNAS, run with the Max Planck Institute and Heidelberg University, found real effects: people meaningfully opened target apps less often, driven mainly by the moment of active choice rather than the breathing pause alone. (One sec's own marketing separately advertises a 57% figure; that number comes from the company, not the PNAS paper.)
Is one sec free?
One sec's free tier covers one app interruption; unlocking the rest needs a paid subscription or one-time lifetime purchase. Dopa Break is free on the web with no per-app limit.
Can one sec and Dopa Break be used together?
Yes. Many people use one sec to interrupt their worst one or two apps and Dopa Break to train the attention span behind all of them.

- Gruning, J., Riedel, F. & Lorenz-Spreen, P. (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.
