Willpower is not enough against social media algorithms! That’s why I made one sec: one sec adds friction to distracting apps to make them less appealing…long-term! And it works really well: we have proven in scientific studies with the Max-Planck Institute, with the German and Danish government, and in dozens more scientific collaborations: one sec has incredible effects on your screen time: app usage drops by 57% on average! …just read our App Store reviews or try it for yourself if you don’t believe me (…you should really try it)! How is one sec different from Screen Time limits or app blockers? - one sec DELAYS access to distracting apps instead of blocking apps completely – that’s an important difference psychologically. - This way, we solve the screen time problem at its roots: long-term & sustainably! - one sec is always on, and makes using social media just slightly more annoying…so you’ll end up using it only when you actually have a reason! Which apps can I use with one sec? - You can set up one sec with any app you’d like to use less / more intentional. - Most popular use-cases are: social media, games, video streaming, dating, stock/coin trading, adult content. - Using one sec with one app of your choice if completely free, for more you’ll need to purchase one sec pro (we also need to finance development of our app!). What if I get stuck scrolling? - No worries, one sec offers a Doom Scroll Emergency Brake: We call it Re-Intervention. - After a set time (e.g. 5 minutes) you’ll be kicked out of social media, and you’ll have to go through an intervention again to unlock more time. Where can I learn more about the scientific background of one sec? → https://one-sec.app/research Can I use one sec to interrupt access to websites as well? → Yes, one sec offers a free Safari extension as well. How does one sec work technically? - one sec uses Shortcuts Automation to toggle a deep breath animation whenever you open one of the configured apps (Instagram, Twitter, YouTube…). - This breaks unconscious social media habits short-term (literally, as soon as you have set it up) and even helps long-term by adding more friction when opening these apps. Integrations: - Structured: one sec blocks apps during unfinished tasks. - LENGO: learn vocabulary to unlock social media. I developed one sec for myself in 2020…and it worked so well I decided to upload it to the App Store. Especially for people with ADHD one sec is a great tool to gain back control for incredible focus and concentration. – Frederik Legal information: Available Subscription Options: one sec pro (annual / monthly / lifetime unlock) one sec can contribute mindful moments to the Health App via HealthKit.

It’s so simple and effective .I have learned that i have muscle memory to open social media app when i got bored. Even though i hid it in the folder far away. I still manage to master the swipe pattern to quickly open the app.This really help me stop that loop.

If you’ve ever opened Instagram for “just a second” and somehow ended up 45 minutes deep into random reels, OneSec might just be the thing you didn’t know you needed.OneSec is a productivity app designed to slow down your phone habits. Its main feature is a delay that pops in every time you try to open a blocked app. Instead of instantly launching TikTok or instagram, you’re forced to sit through a short pause, sometimes with a breathing exercise or a simple puzzle. It sounds small, but that tiny moment of friction is surprisingly powerful. It breaks the loop of brainless scroll cycle and actually makes you stop and think: do I actually want to open this right now?Most of the time, my honest answer is no.What really stood out to me was two specific features. The first is scheduled blocks. You can set certain apps to be fully off-limits during specific hours. I blocked all social media during work hours and the difference was pretty noticeable almost immediately. I stopped jumping between tasks every five minutes and actually got stuff done. My focus felt way more steady throughout the day, which really surprised me because I didn’t expect one small change to matter that much.The second is the intentional app-switching interrupt, which re-triggers the delay every 10 minutes even while you’re already inside an app. So even if you slip into a scroll session, it keeps reminding you and asking if you really meant to be there. That feature alone is what makes OneSec different from just setting a screen time limit. It doesn’t just cut you off — it keeps checking in.The app isn’t perfect. Setting everything up takes some time. you’ll probably block something you didn’t mean to, miss a site you should’ve blocked, and have to go back fix it a few times. There was also one moment where I needed to buy something and realized I’d blocked the whole browser. A little annoying. But OneSec does let you set up an emergency unlock, like a long delay to temporarily get access back, which helped me out more than once. Once you get the settings right though, it pretty much runs itself.Overall the small annoying stuff are really nothing compared to what you get back. I felt less anxious, more focused, and just more present during the day. Not because I suddenly became a more disciplined person but because the app quietly took away the easiest escape route. It’s kind of hard to explain until you actually try it, but losing that constant easy access to scrolling makes your day feel a lot calmer.If you’re someone who picks up your phone without even thinking about it, OneSec is genuinely worth trying. It won’t fix everything, but it gives your brain a fighting chance.

Hi I love your app. It had help me concentrate and focus but there is a glitch that made it so that after the scheduled time it won’t immediately disable the block.

Version 5.2 is a big update for one sec — but instead of adding headlining new features, this release focuses on improving what’s already there and making everything more reliable. - Re-Interventions now work with websites via our Safari extension. - Fixed an issue where 23-hour blocks could not be started. - Journaling Intervention redesigned for iOS 26, plus many bug fixes. - Journal entries now reliably sync via iCloud with our companion app Reflective. - Conversational Reflection is now faster and more reliable. - Fixed an issue where the Block Live Activity didn’t start when launching a block via the widget. - Bug fixes for the Intention Picker. - During strict blocks, screen time permissions can no longer be re-authenticated and apps cannot be reassigned (to prevent cheating). - The widget now refreshes regularly to always show up-to-date usage data. - Many additional bug fixes and improvements throughout the app. I really hope you like this update and the continuous improvements we’re making to one sec. If you do, leaving a quick review on the App Store would help us a lot. Thanks for your support! Frederik
