Stop opening social media on autopilot. one sec adds a short pause before distracting apps so you can choose what deserves your attention. This principle works really well: we have gained scientific evidence in numerous research 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 is 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. one sec is covered by U.S. Patent 12,468,828 B2.

OFF has been conceived as a digital tool to help you build healthier digital habits. It allows you to set focus sessions to block the device for a pre-set time, allowing you to study or complete an important task without distractions. It also helps limit scrolling on apps like TikTok, Instagram, or Twitter, where we often end up spending more time than intended; you will also be able to set the maximum number of hours you want to spend on a specific app or on your phone overall; and create schedules to limit usage — for example, during work hours, before going to sleep, or when you wake up in the morning. Beyond the blocking features, users can also access screentime statistics to help them understand better their phone usage, adapting the features to their needs. Additionally, something that makes OFF different to the rest of apps is the strictness in the skipage of the blocks. We don't want you to skip the blockage easily and we want you to commit to your own set limits. Enjoy the most advanced blockage options at zero cost.

Verdict
The clearest difference is ratings volume: one sec | screen time + focus at 24K against OFF's 3. one sec | screen time + focus also leads on device support (4 vs 1) and iOS requirement (15.0 vs 17.0). OFF's advantage is review sentiment (100% vs 76%). On price, rating, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. one sec | screen time + focus sells 6 in-app purchases, starting at $6.99 per month and OFF sells 12 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
OFF holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: one sec | screen time + focus has 24K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 76% of one sec | screen time + focus's written reviews are positive against 100% of OFF's.
one sec | screen time + focus ships an update every 2 weeks, OFF every 3 weeks. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
