About one sec | app blocker, focus
one sec forces you to take a deep breath whenever you open distracting apps.
It’s 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 – and forces you to reflect on your actions – while they happen.
🤳 Balanced social media use
App usage drops by 57% on average thanks to one sec – proven by science!
🧑💻 Productivity
Having two more weeks per year not spent on social media – to work on your projects & to recharge!
🙏 Mental health
High social media usage is often related to depression and anxiety symptoms.
⚡️ ADHD relief
Users praise one sec as the “holy grail for ADHD relief”.
🏃 Sports
Studies have shown that reduced social media use leads to increased sport activity.
🚭 Quit smoking
Studies have shown that reduced social media use leads to reduced smoking behavior.
💰 Save money
Prevent impulse purchases with one sec.
🛌 Sleep better
Prevent scrolling mindlessly before you go to bed and right after waking up.
With one sec, you‘ll notice both a short-term and long-term effect on your social media usage:
1. Unconscious phone habits are prevented right away (“Why did I even want to open that app?”) and
2. Long-term habits change because these apps appear less appealing to your brain (their “dopamine on demand” 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. You’ll 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
