About one sec | screen time + focus

In contrast to Screen Time, one sec delays access to apps and websites instead of blocking them completely – this is fundamentally different than any other screen time tool you’ve tried before!

Have you tried a digital detox? And it did not work, because you fall back into your habits immediately?

Well here is the solution:

one sec solves our unhealthy phone relationship at its roots: by making distracting apps less appealing, our brains lose interest to open them all the time without proper intention.

The effectiveness of one sec has been confirmed in a peer-reviewed scientific study with the Max-Planck Institute and Heidelberg University: app usage drops by 57% on average! Long-term!

Fight the social media algorithms and win back control over your phone usage & your subconsciousness!

“one sec” uses Shortcuts Automation to toggle a deep breath animation whenever you open one of the configured apps (Instagram, Twitter, YouTube…). This breaks unconcious 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.

Did you really want to open Instagram? Or was it just because you're bored waiting for your bus?
This app helps you to reflect your actions, thoughts, and feelings; disrupting harmful social media habits with mindfulness.

On top of that, “one sec” also contributes your mindful moments to the Health App via HealthKit.

Especially for people with ADHD one sec is a great tool to gain back control for incredible focus and concentration.

Integrations and collabs:
- You can set up one sec to sync tasks with Structured, so you won't be able to access social media apps during ongoing unfinished tasks.
- You can set up one sec to learn a new language with LENGO, so every time you open social media, you have to answer a handful of vocabularies.

Available Subscription Options:
one sec pro (annual / monthly / lifetime unlock)

What's New in the Latest Version 3.8.2

Last updated on Mar 19, 2024

Old Versions

Another small, but important bug-fix update:

This update fixes an issue where on iOS 16 and earlier the “Closing Automation” and “Start Block Session” Shortcut would not work anymore.

This time it’s not my fault, it’s something that Apple has acknowledged in their release notes (including a workaround which I have now applied in this update, see FB13664020):
https://developer.apple.com/documentation/xcode-release-notes/xcode-15_3-release-notes

Sorry for the inconvenience!

Sorry about that!
This update should fix that.

And if you haven’t checked out the widgets so far:

one sec has three amazing widgets you should give a try (now that they work again ;) ):

1. The “Last Pickup” lock screen widget: shows which app you used last and how long ago.
2. Statistics Widget: Time spent + open attempts for the last 24hrs.
3. Block Session Widget: Start block sessions right from your Home Screen.

Sorry for the bug!

Fixes an issue where the "always type intention" option would end up in an endless loop when opening an app.

Sorry about the trouble!

3.5

May 19, 2023

May 18 is Global Accessibility Awareness Day!

In spirit of this day, I have been working on making one sec more accessible for everyone:

This update adds a new dyslexic font to one sec:

The dyslexic font is specifically designed to assist individuals with dyslexia in having a more comfortable and efficient reading experience.

By incorporating unique letter shapes, varied spacing, and other visual enhancements, this font aims to reduce common reading difficulties faced by those with dyslexia, such as letter-swapping or mirroring.

If enabled, all tutorials will be displayed using the dyslexic font, potentially making it easier for users with dyslexia to process and understand the content.

———

On top of that, this update contains a ton of smaller bug fixes and improvements.

And if you look closely, you can spot some hints on what will come with the next big update.

Also, of course, includes the improvements from the small update 3.4.1:

Journal with joy: join the journey with one sec’s new journaling intervention:

- If enabled, the journaling intervention will prompt you to write 25 words the first time you open social media in the morning (and in the evening). Otherwise, you’ll see the normal intervention.
- You can also directly start a new journal entry from the “Good Morning Countdown” or healthy alternatives.
- Like all data in one sec, your journal entries are stored on your device (and in your private iCloud container), I cannot access them.
- Journaling, and reflecting on your emotions and what you’re thankful for is a very healthy habit that sparks happiness (according to science)! I hope that one sec disrupting a bad habit can help to spark new, positive habits in your life. That’s why I created this feature.

◆ How to enable the new Journaling Intervention ◆

Go to one sec settings → "Healthy Habits" and you’ll be able to enable morning / evening journaling interventions. Force yourself to journal, reflect on your feelings the first time you open an app after waking up—and again in the evening before going to bed. You can also always add entries to your journal via the "Healthy Alternatives" within interventions.

◆ Journal Emotion Explorer ◆

On top of that, I’ve added an “emotion explorer” into the Journaling Intervention. I know it can be hard sometimes to figure out the (complex) emotions that we feel, and I believe structuring them can help a bit to navigate and identify the right ones.

◆ Journal Prompt Generator ◆

Depending on the context, the journal can optionally display prompts:

- Morning Reflection
- Evening Reflection
- Mid-Week Reflection
- Week Reflection
- Month Reflection

◆ Journal History ◆

You can see all journal entries in one sec → customize → Journaling → History. It’s such a cool thing to read the entries of your past self – even if it’s just two weeks ago.

…and there is even more:

◆ Sync with Structured: adding Colors! ◆

You can now adapt one sec’s intervention behavior based on the color of ongoing, unfinished tasks in Structured. Please make sure you have both the latest Structured & one sec version installed to make this work. You can find the new options in one sec → customize → Structured.

◆ Some small improvements and bug fixes ◆

- Fixes an issue where the one sec Safari Extension wouldn’t block apps during active block sessions while the intervention schedule was off.
- You can now allow BeReal to be opened once per day without intervention.
- You can now edit app-specific settings at the bottom of each app statistics.
- Fixes an issue where the Intention Picker wouldn’t be shown for the “Follow the Dot” intervention.
- Fixes an issue where the status bar and the outer progress indicator wouldn’t be visible for apps with a complete dark background (e.g. BeReal) during the “Follow the Dot” intervention.
- Fixes an issue where the iOS Safari Extension would state that it’s set up with one sec even through you’ve pressed cancel.

I really hope you enjoy these big + small improvements!
