About this app
one sec forces you to take a deep breath whenever you open distracting apps.
Itās as simple as effective: You will reduce your social media usage just by becoming aware of it. one sec is the focus app that tackles the problem of unconscious social media use at its root. It is designed to change your habits on a long-term basis.
one sec works so great because it is fully automated ā and forces you to reflect on your actions ā while they happen.
š¤³ Balanced social media use
App usage drops by 57% on average thanks to one sec ā proven by science!
š§āš» Productivity
Having two more weeks per year not spent on social media ā to work on your projects & to recharge!
š Mental health
High social media usage is often related to depression and anxiety symptoms.
ā”ļø ADHD relief
Users praise one sec as the āholy grail for ADHD reliefā.
š Sports
Studies have shown that reduced social media use leads to increased sport activity.
š Quit smoking
Studies have shown that reduced social media use leads to reduced smoking behavior.
š° Save money
Prevent impulse purchases with one sec.
š Sleep better
Prevent scrolling mindlessly before you go to bed and right after waking up.
With one sec, youāll notice both a short-term and long-term effect on your social media usage:
1. Unconscious phone habits are prevented right away (āWhy did I even want to open that app?ā) and
2. Long-term habits change because these apps appear less appealing to your brain (their ādopamine on demandā effect fades away).
one sec is also available for your desktop web browser: https://tutorials.one-sec.app/browser-extension-installation
We have made one sec free to use with one app!
If you would like to use one sec with multiple apps, please upgrade to one sec pro. Youāll also get access to lots of additional features and customization options.
This effect has been confirmed in a study with the University of Heidelberg and Max Planck Institute where we detected a reduction of social media usage by 57% thanks to one sec. Read our peer-reviewed paper: https://www.pnas.org/doi/10.1073/pnas.2213114120

A great app. You can trial it on one app and I liked it so much I paid for the pro version. It's made me aware of just how much time I was wasting on games. I can still play, but I get messages asking me if I really want to access a game and reminding me when I've reached the time I allocated to play. That intervention often makes me decide to stop playing. The android version doesn't have as many options as the IOS version, which was released first, but the developer is working on that.

Amazing and super simple app for its purpose. Only being able to test one app using the free version is quite limiting, and for a full purchase price of Ā£30 (or a monthly subscription) it's quite difficult to assess the utility of the app using only one restriction, but it's hard to complain about something that's free.

The app is becoming more and more glitchy, I was using one app, but the intervention would come on for another app. The intervention will load when you try to do something within an app before the timer has run out, or atleast it seems that way as it seem very coincidental that the timer always runs out when I click to view a comment or any kind of action within an app rather than just at random. But I've found I've just tolerated the interventions rather than changed my behaviour.
