one sec—tiempo pantalla y foco
Limitar apps y websites
Gratis · Compras dentro de la app
¡La fuerza de voluntad no es suficiente contra los algoritmos de las redes sociales!
Por eso creé one sec.
one sec añade un pequeño retraso al abrir apps que distraen, para que resulten menos atractivas con el tiempo.
Y realmente funciona: lo hemos demostrado en estudios científicos con el Instituto Max-Planck, con el gobierno alemán y danés, y en muchas otras colaboraciones científicas.
one sec tiene efectos increíbles en tu tiempo de pantalla:
¡el uso de apps disminuye 57 % en promedio!
…lee nuestras reseñas en el App Store o pruébalo tú mismo si no me crees (de verdad deberías probarlo).
¿En qué se diferencia one sec de los límites de Tiempo de uso o de los bloqueadores de apps?
• one sec retrasa el acceso a apps que distraen en lugar de bloquearlas por completo.
• Así resolvemos el problema del tiempo de pantalla desde la raíz, a largo plazo.
• one sec siempre está activo y hace que abrir redes sociales sea solo un poco más molesto…
por lo que terminarás usándolas solo cuando realmente tengas una razón.
¿Qué apps puedo usar con one sec?
Puedes usar one sec con cualquier app que quieras usar menos o de forma más consciente.
Usos populares:
• redes sociales
• juegos
• streaming de video
• apps de citas
• trading de acciones o criptomonedas
• contenido para adultos
Usar one sec con una app es completamente gratis.
Para más apps necesitas one sec pro.
¿Qué pasa si me quedo atrapado haciendo scroll?
one sec incluye un freno de emergencia contra el doomscrolling, llamado Re-Intervention.
Después de un tiempo (por ejemplo 5 minutos) saldrás automáticamente de la app y tendrás que pasar otra vez por una intervención.
¿Dónde puedo aprender más sobre la investigación científica?
→ https://one-sec.app/research
¿Puedo usar one sec también con sitios web?
Sí. one sec también ofrece una extensión gratuita de Safari.
¿Cómo funciona técnicamente?
one sec usa Automatizaciones de Atajos para mostrar una animación de respiración profunda cuando abres una app configurada.
Esto interrumpe los hábitos automáticos de redes sociales y añade un pequeño retraso al abrirlas.
Integraciones
Structured — bloquea apps durante tareas sin terminar
LENGO — aprende vocabulario para desbloquear redes sociales
Desarrollé one sec para mí en 2020.
Funcionó tan bien que decidí publicarlo en el App Store.
Especialmente para personas con TDAH, one sec puede ayudar mucho a recuperar el control y mejorar la concentración.

Works great in Safari, and my usage of distracting websites has decreased.

It let me take control of my screen time again!

It’s a great app to help you stay away of apps and I like that the blocking is great but there should be a way to stop the blocking when it’s an emergency:(

6.1 20 oct
Small & important bug fixes for an ongoing research project inside one sec.
6.0.2 29 sep
Here’s the most impactful update we’ve ever shipped for one sec:
With one sec 6.0 and the new big iOS update you no longer have to set up Shortcuts automations manually!
Simply tap on “Add Intervention” to automatically import the automation.
This makes one sec’s setup a one-step process, instead of a technical 10-step process.
And this was by far the biggest complaint we’ve heard over the years for you, our users.
Besides that, with this update one sec becomes better in every aspect:
- Big accessibility improvements (especially voice over)
- Bug fixes and performance improvements
- Liquid Glass design improvements
I’m really proud that we’re able to ship such a significant improvement for one sec alongside the big iOS update.
And I’m especially grateful that I got to work on this amazing update with the best team I could dream of!
Hope you’ll enjoy this update as much as we did working on it this summer :)

5.2.7 3 jul
This is a small update with big impact:
If you’re running iOS 26.5 (or newer) you will no longer have to do the notification dance when going through Re-Interventions or Delayed Interventions.
When you press the “Intervention” button, the breathing exercise (or other intervention of your choice) will simply show up.
On top of that, we’ve made small improvements to the Structured integration & the block tab in general.
Hope you’re enjoying our little updates over the past few weeks!
If you like one sec, it would help a lot if you could leave us a nice review on the App Store. Thank you!
– Frederik
5.2.6 2 jun
This is probably one of the most impactful bug fix updates yet for one sec:
- With this update, one sec implements a series of improvements with apps connected via screen time: if you’re using iOS 26.5 (or newer) there should now be way fewer glitches and issues. This is really a big step forward. I’d like to thank Apple for the great collaboration making that happen. Looking forward to more screen time bug fixes in the future :)
- On top of that, this update addresses an issue where apps shielded by delayed interventions could be accidentally unlocked even before the next full hour hast started. Sorry about the trouble!
- After our last performance focused update, this one also implements a series of smaller bug fixes and addresses UI glitches (especially inside interventions).
- Implements improvements for an ongoing research project.
- Fixes issues regarding the Shortcuts app lock feature.
- Fixes an issue where blocked websites were not exposed in the block preview.
- Improves layout for Dynamic Island timer, especially for longer intentions.
- Fixes an issue where the start / end time stamps of Focus Filters were not displayed correctly in the block tab.
5.2.5 20 may
- Performance improvements for one sec’s interventions.
- New research infrastructure powering future studies within one sec.
- Localization improvements.
- Dynamic Island improvements.
- Adds new math intervention.
- Improved random text intervention.
5.2.4 12 may
- Performance improvements for one sec’s interventions.
- New research infrastructure powering future studies within one sec.
- Localization improvements.
- Dynamic Island improvements.

5.2.3 6 may
This is a smaller update which includes a bunch of bug fixes and UI improvements:

- Improves one sec’s Safari extension, especially the Re-Intervention.

PS: We are super busy working on the next big update for one sec :)
5.2.2 26 abr
Version 5.2 is a big update for one sec — but instead of adding headlining new features, this release focuses on improving what’s already there and making everything more reliable.

- Fixed an issue where 23-hour blocks could not be started.
- Journaling Intervention redesigned for iOS 26, plus many bug fixes.
- Journal entries now reliably sync via iCloud with our companion app Reflective.

- Many additional bug fixes and improvements throughout the app.
I really hope you like this update and the continuous improvements we’re making to one sec.

5.0.3 24/09/2025
We’re celebrating one sec’s 5th birthday this month.
It’s hard to believe that it’s been 5 years already since I started working on one sec.
I’m grateful every day I get to work on such an impactful app with the best team I could wish for!
This summer, we’ve been working extremely hard on a large list of new features, improvements and bug-fixes and we can’t wait to get it into your hands.
We decided to call this update:
one sec 5.0
This update brings…
…an all-new block tab: upcoming & past blocks at a glance (no matter if they are triggered by a Schedule, a manual Block, Good Morning Countdown, Focus Filter, a Structured task…).
…an all-new tips tab with hands-on tips to get the most out of one sec & your new life.
…a new conversational reflection intervention using the new on-device LLM helping you to reflect even more on why you open apps.
…a much improved ”Good Morning Countdown“ that now integrates with the new no-mercy alarm clock app “Awake”.
…many many design refinements and bug fixes throughout one sec.
If you like one sec & our continuous work on it, please take a moment to write a review on the App Store.
Thank you very much for your support!
