Features
7.5

The core function that One Sec uses to make users more productive is a pause before opening the website. When I open websites I have defined, such as Twitter, a gray page with a countdown appears. During this period, I was reminded that I didn't want to spend so much time on Twitter and asked myself whether this was intentional or just a reflex out of boredom.
This worked very well for us in the test and there were no problems.


It is also possible to adjust the delay individually. If you only need the reminder but don't want to be disturbed too much, you can set the timer to just one second, or several seconds if you prefer.


Finally, a useful function is the analysis dashboard. This provides analyses of your surfing behavior, showing you at a glance how often you try to open these websites during the day. However, we would like to see more analysis options here.


All in all, the functions are kept very simple; further options for time tracking would be an advantage here so that you don't need additional extensions. These functions are already available in the mobile app. One Sec is a good addition to existing time management extensions.

It also offers an allow list and user-defined rules. This means that you can make adjustments to the rules or allow advertising on certain websites that you want to support.

Performance
9.5

In our test, we did not notice any delays or slowdowns due to the extension.
Regular updates are also released to improve performance and fix bugs.

9.0

A recent user complained in a review that it had YouTube problems that affected the performance and speed of the website. In our test, we did not notice any performance problems. The extension generally works quickly and reliably. There are also regular updates, so the problem may already have been solved.

Design
8.0

The user interface is clean and minimalist, and this also applies to the setup and settings. The extension offers an effective use of visual elements for taking a break by displaying a preset screen with a countdown. There would be potential for improvement here if the screen could be customized.

9.2

The design is very clear and well-organized. The display of the settings is significant for adblockers. Here, great importance has been attached to user-friendliness and highlighting the customizable settings.

Value for Money
9.2

The browser extension is completely free of charge. However, you only get a small number of functions. For anyone who only needs the basic function, this is unbeatable value for money.

OneSec also offers an app with additional functions. At $4.99/month or $49.99/year, it also has a good price-performance ratio.

9.2

The free browser extension offers numerous functions that worked perfectly in the test. Compared to competitors, you get many functions here that others offer for a fee.
If further functions are required that can also be used outside the web browser, AdGuard Adblocker also offers an app that is subject to a charge. We consider the current lifetime prices to be fair for the services offered.

Ease of Use
9.5

The installation process was quick and straightforward. This also includes the setup, which is very intuitive with clear step-by-step instructions. Everything is also well explained in the settings menu afterward, so everyone should be able to find their way around.

set up
9.5

Installation is quick and easy. What impressed us in comparison to other competitors was that AdGuard Adblocker clearly shows which functions it offers and explains them in the introduction, and you can activate them directly if you wish. The extension therefore attaches great importance to ensuring that every user recognizes and uses the options. With competitors, some functions were somewhat hidden in the settings.

Configure
Security & Privacy
9.5

Data usage is described transparently in the privacy policy, which places great value on user privacy.
This is also reflected in the fact that the features already work with minimal authorizations so that not much private data needs to be tracked.

8.0

Strong privacy protection by preventing tracking. Also features malware detection and blocking, although public complaints could raise concerns.
Overall, AdGuard provides transparency in its privacy policy and limits data collection. Some practices, such as filing public complaints and reviewing website visits, should be critically questioned.

Conclusion

One Sec is a tool that encourages mindful browsing by introducing a pause every time you want to access a distracting website.
Although it stands out for its simplicity and effectiveness, its limited functionality means that it should only be seen as a supplement in the area of time management. Overall, however, it is a valuable tool for anyone looking to improve their online productivity.

AdGuard Adblocker is, in our opinion, a very good ad-blocking tool compared to its competitors, offering a range of features in the free extension that you often have to pay for. In our test, all ads were blocked. Other ad blockers currently fail because of YouTube's advertising videos, but AdGuard currently seems to have this fully under control. Overall, it is the choice for a free browser extension with many features.

Finally, we would like to point out that our test is about the browser extension. If you work in different browsers and don't want to install a new extension in each one, or if you work a lot in apps that carry out advertising and tracking, AdGuard Adblocker offers an app for comprehensive security outside the browser.

The AdGuard app allows you to block advertising in other apps outside of your web browser, for example, and keep your data secure. Here is an overview of the additional functions:

Comparison

Currently, you have the opportunity to purchase the app as a lifetime plan. Here you can decide whether the app should be installed on 3 or 9 devices.
