This is the universal build of one sec 2.4.4. It contains native libraries for every CPU architecture (arm64-v8a, armeabi-v7a, x86, x86_64), so it installs on any Android device. The trade-off is size — it's larger than per-architecture variants. Pick this one if you're unsure which CPU your phone has, or if you plan to share the APK with multiple devices.

App Description
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:

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:

Frequently Asked Questions about one sec APK
This is the universal variant — a single APK that contains native libraries for every CPU architecture. It installs on any Android device but is larger than per-architecture variants.
Yes — the APK's signature has been cryptographically verified against the publisher's signing key. The SHA-256 hash is shown in the File Information panel so you can independently confirm the file matches the original release.
Android 29 (API level 35) or newer. Older devices will refuse the install.
Install a free app like 'CPU-Z' or 'Droid Hardware Info' from the Play Store and look at the ABI / Instruction Set row. Most phones made after 2017 are arm64-v8a; if in doubt, download the universal variant.
All variants are functionally identical — same features, same version. They differ only in which CPU architectures the native code is compiled for, and (sometimes) which screen densities the included graphics target. Pick the one that matches your device for the smallest install size, or pick 'Universal' if you're unsure.
