Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About one sec | screen time + focus
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.

- 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.

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.

Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About one sec | app blocker, focus
Take a deep breath and stop scrolling! one sec is the screen time limit app with science behind it: 57% fewer app openings on average, confirmed in a peer-reviewed study in collaboration with Max-Planck-Institute.
Most social media use happens on autopilot. one sec interrupts it right at the root by breaking the dopamine loop behind every mindless scroll. This is effective in two ways:
1. Unconscious app openings are prevented right away (“Why did I even want to open that app?”).
2. Long-term habits change because your brain gets rewired: apps appear less appealing.
🔒 Privacy by design: one sec does not sell or analyze your data.
🛠️ FEATURES
- Breathing pause: take a deep breath before distracting apps open
- App blocker: block Instagram, TikTok, or any other app instantly or on a schedule
- App time limit: block apps and websites after a set amount of time
- YouTube Shorts blocker & Instagram Reels blocker: remove in-app features while keeping the rest of the app
- Focus times: schedule phone-free hours during work, study, family time or bedtime
- Porn blocker: block porn sites and lock the setting so you can't switch it off on a whim
- Screen time stats: track how often you reach for an app and how much time you’ve saved
- Desktop Browser extension: set up one sec on your desktop web browser to block websites
- …and more!
📊 WHAT RESEARCH SHOWS
- 57% fewer app openings on average, in a study with the Max Planck Institute for Human Development and Heidelberg University (published in PNAS)
- 36% less social media use among teens, in a field experiment by the Danish Competition and Consumer Authority
- Friction-based apps like one sec have the strongest evidence of all screen time tools, according to a University of Cambridge report.
- one sec is part of research projects with 30+ universities and federal institutions, like the University of Cambridge, LMU Munich and the German Federal Agency for Child and Youth Protection.
- one sec users save more than 3,000 years of scrolling every week.
