Originally, we launched one sec on iOS when Frederik, our founder built one sec to cure his own phone addiction.

With millions of happy users, we are confident that the app can help you cure yours, too.

To help more people, we launched one sec on Android in 2023. Soon, the same simple concept was proven effective there, too.

With almost all of the great features of the iOS app, and more coming with every update.
