What's New in one sec | screen time + focus

5.2.9

August 1, 2026

- Fixes an issue where the “Last use” label in the intervention was displayed using a wrong text color. - Fixes an issue where the corner radius of the breathing animation was not correct. - Fixes an issue where the about page was not laid out correctly on iOS 15. - Manual block durations can now be configured up to 200 hours. - Scheduled blocking more clearly indicates that websites are supported; “Apps” is renamed to “Blocked.” - Corrected app counts in blocking configurations by avoiding duplicate-counting apps. - Unlocking one sec settings now enforces at least a “long” intervention duration. - Fixed a crash when editing interventions while healthy alternatives are visible. - Fixed the breathing transition layout during iPad rotation. - Fixed a potential Follow the Dot crash on future iOS versions. - Improved the “last 24 hours” usage text color for different intervention backgrounds. - Fixed the Safari extension typo: “one sec is no set up” → “not set up.”

Great app on iOS but experience between Mac and iOS needs to be more so the same

Like how its genuinely difficult to get around on iOS but way too easy to get around on Mac, especially through just disabling the extension or (if a website is blocked), clicking reload without content blockers. Frustrating how there’s no blocking schedule available on Mac for free but is available on iOS as blocking is the main thing that stops me ruining my sleep schedule through social media apps. Better integration fully with screen time on Mac would be better than an extension (or alongside an extension). Still an awesome utility and has definitely decreased my screen time 3-fold easily

Most effective screen time app

I’ve used and paid for subscriptions, apps like opal etc. This app is by far the most effective, it doesn’t use simulator type methods to get you hooked on not using apps, but enables you to think consciously about your choice and doesn’t force you to stay away if you actually WANT to use it.

Cool App

Kinda problematic they allow you to strict-block without setting an app, which combined with some of the other features, can be sort of a phone breaking feature. But the Detox feature is great!

I tell all my friends about this!

one sec has been almost life-changing. It used to be one of my most opened apps because it interrupted all the times I tried to doomscroll! I love this app and it was so helpful. Setting it up, takes a little bit of work, but it was so worth it! My screen time has gone down significantly, and I have so much better boundaries on my screen usage. Every time the topic of looking at your phone too much comes up in conversation, I always recommend this app!

FAQ

What does this app do?

This app introduces intentional friction to distracting apps and websites, making them less appealing for long-term use. It works by delaying access to these apps instead of completely blocking them, which is a key psychological difference that helps users build sustainable habits and reduce overall screen time.

How does it differ from standard screen time limits?

Unlike traditional screen time limits or app blockers that completely prevent access, this app adds a slight delay or interruption when you try to open a distracting app. This subtle friction is designed to break unconscious habits and encourage more intentional usage, leading to a significant reduction in app usage over time.

Is this app free to use?

The app offers a free version that allows you to set up limitations for one app of your choice. For access to more features and to set up limitations for multiple apps, a premium version is available through various subscription options, including annual, monthly, and lifetime unlocks.

What kind of apps can I use this with?

You can configure this app with any application you wish to use less or more intentionally. Popular use cases include social media platforms, games, video streaming services, dating apps, stock trading apps, and adult content sites. A free Safari extension is also available to interrupt access to websites.

What happens if I get stuck scrolling?

The app includes a feature called 'Re-Intervention' which acts as a 'Doom Scroll Emergency Brake.' After a set period of time, such as five minutes, you will be automatically removed from the social media app. You will then need to go through the intervention process again to unlock more time, helping you regain control.
