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.

Predy is a study timer and planner that helps you start studying, stay consistent, and make your progress visible. Use a study timer, Pomodoro, stopwatch, or manual entry to track learning time and build a routine that lasts. In Predy, goals are organized as projects, with tasks and work logs contained within them. Tasks can be managed by project, priority, deadline, and estimated time, preventing work from becoming scattered. Because all work logs are tied to projects, progress accumulates automatically, making it easy to see where you stand. Estimating required time in advance also helps users realistically understand what it will take to reach deadlines, reducing failed plans. The first problem Predy tackles is “not being able to start.” Work tracking supports Timer, Pomodoro, Stopwatch, and manual entry, allowing flexible use depending on the task and mental state. StudyWithMe mode further lowers the barrier by creating a focus-friendly atmosphere with immersive visuals and ambient sounds. On days when starting feels hardest, AutoPilot is especially effective. With one tap, a 2-minute timer begins alongside a simple starter action, such as tidying your desk. After that, you naturally move into a focused 20-minute session. This uses behavioral activation—you don’t start because you’re motivated; you get motivated because you started—minimizing resistance and building momentum naturally. Predy is also designed to make you want to continue. Daily login and task completion bonuses grow with streaks, while rankings visualize productivity through multiple metrics such as project completions, focus level, efficiency, total work time, and consecutive days. Even “just one minute today” feels meaningful, often leading to longer sessions. Consistency is supported not by grit, but by structure. Progress is clearly visible through analytics that show work volume and time for today, this week, and this month. Seeing effort accumulate creates a sense of achievement and naturally leads to “Maybe I’ll do a little more.” Predy’s core differentiator is Prediction. Before working, users estimate how long a task will take and compare it with the actual result. Feedback at project completion helps clarify why estimates were off. Repeating this process improves planning accuracy, reducing deadline overruns. Predy doesn’t just manage tasks—it trains how to plan. Predy isn’t only for your best days. It’s for people who tried task management apps many times and couldn’t keep going. By lowering the barrier to starting, creating reasons to continue, and leaving visible proof of effort, Predy helps users try again. From “I have to push myself” to “I’ve already moved forward.” Predy is designed to make that state part of everyday life.

Verdict

The call

The clearest difference is ads: one sec | screen time + focus at none against Predy's shown. one sec | screen time + focus also leads on ratings volume (24K vs 1) and iOS requirement (15.0 vs 17.0). Predy's advantage is update cadence (every 2 days vs fortnightly). On price, rating, review sentiment and in-app purchases there is nothing between them.
