one sec

Distracting apps made less appealing – scientifically

Every time you try to open your favorite apps, wait. Take a deep breath in, and let it out slowly. one sec gives you the chance to pause and think twice – before you get sucked into an endless loophole designed to draw you in for hours again.

The effectiveness of one sec has been confirmed in a peer-reviewed scientific study with the Max-Planck Institute and Heidelberg University.

Gain back control over your time

You just wanted to check that one message – and ended up scrolling on Instagram for 30 minutes? Social media is designed to keep you hooked to spend as much time as possible. Time that could be spent so much better – with your family and friends, getting work done or for your hobbies and wellbeing.

On average, an online user spends 17 hours per week on social media.1

Studies show that heavy social media use is associated with an increase of psychological distress, depression, and anxiety.2

The majority of young adults meet the criteria for problematic internet use.3

Science-based approach

Recommended by psychologists5

Our social media habits are the outcome of psychological mechanisms that apps trigger in our brains. They use the system of instant gratification which releases dopamine whenever we perceive a like or a message on our phone.

one sec’s approach is to break those habits. By making you wait longer for social media to open, your brain loses interest in those (destructive) short-term dopamine hits.

A focus app for more than short-term productivity

Many apps and tools block social media for a limited amount of time to help you focus. This might increase your productivity for the moment, but the real problem – your habitual urge to check apps and websites to get that dopamine boost – stays.

How it works

Automated second thought

Realize and question every single attempt to use social media.

one sec works fully automated and is triggered by every attempt to open the app or website of your choice. You will be forced to take a deep breath and then decide: Do you really want to spend time there? Or was it just an impulse out of boredom or stress?

Block social media apps that distract you the most

Configure one sec to get triggered whenever you open Facebook, Instagram, Twitter, WhatsApp, TikTok or any other app on your iPhone or Android device.

You can block websites as well

No matter if it’s a news site, your favorite forum or adult content – keep yourself from wasting time on any website. It’s the same effective technique and configuration only takes a few minutes.

Act intentionally

If configured, one sec forces you to set an intention for opening apps. By thinking about your planned actions in the app beforehand, you will spend less time doing anything else.

Get reminded about your intention

Keep catching yourself scrolling through social media feeds for ages – even though the plan was only to read that one message? This is over now.

one sec will send you a notification after one to five minutes to check if you‘re still following your intention. This helps you to reflect if you still need to have that particular app opened.

Focus Sessions

During Focus Sessions, one sec won‘t allow you to open any of the configured apps – and there‘s nothing you can do about it. Enjoy pure focus and finally get things done!

Watch your progress

one sec visualizes your progress in nice diagrams and comparisons.

See how much time you’ve saved already – watching your progress reflected in numbers is incredibly motivating!

Keep your focus.

Breathing Exercise

Forces you to take a deep breath before opening the target app.

Follow the Dot

Follow the dot with your finger for 10 seconds to unlock the target app.

Black Screen

Your screen turns black for 10 seconds before allowing you to continue to the target app.

Rotate Phone

Rotate your phone three times around its axis to unlock the target app.

Minimal Breathing Exercise

A simple version of the breathing exercise.


Look in your own eyes and tell yourself that you really want to open that app right now.

Healthy alternatives

Set up concrete, healthy alternatives to help you get away from your social media habits: looking at family photos, doing sports, calling a friend, drinking water, reading a book, or listening to music are all great alternatives that will be suggested right when you need them.

“Brilliant. Best mindfulness app in existence.”

“It’s exactly what I needed. A forced break from repetitive, mindless social media. Absolute pure genius. It takes a few minutes to set up but it is completely worth it.”
