Neuroscience is the key to your productivity and now there’s an app for that. No, it’s not a To-Do List, a supportive affirmation or an alarm that reminds you to get back to work. It’s a tool that allows you to uncover when you are most likely to get things done. Peak Time is the long-kept secret of successful entrepreneurs and dynamic over-achievers. It’s your body’s “magic hour”—the time of day when you’re 2-100x times more productive than any other time of day. • Some people call it a “flow state”. I call it awesome. It’s when you can plow through 50 emails in 30 minutes… • Write 2,000 words without batting an eye… • Handle an important sales call while driving through rush-hour traffic with a crying toddler in the back seat… You get the point. And all it takes to reach insane levels of productivity is a few taps of your finger. Yup, you read that right. How it works • Download and open the Peak Time App • Select either right or left hand • When prompted, start tapping the “Start Session” button as quickly as you can • Stop when indicated • Allow the screen to reload to “Start Session” and then start tapping again as quickly as possible, taking care to use the same hand • Stop when indicated • Select the opposite hand—if you chose “Left” first, now choose “Right”, if you chose “Right” first, now chose “Left” • Repeat steps 3 through 6 again. Repeat this process several times throughout the day, for no less than a full week. At the conclusion of the week, look at the statistical map of your results and discover your Peak Time!

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.
