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.

9.3

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

During our test, AdBlocker Ultimate did not experience any performance issues. Ad blocking worked flawlessly on all platforms tested, so there were no disruptions to websites caused by advertising.

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.

8.5

The user interface is clearly laid out and should be easy to use for every user. The settings page is also very clearly laid out. Only the constant reference in the extension pop-up to the paid Windows desktop version detracts somewhat from the design.

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.

9.5

The Web Extension is free of charge. Compared to other free providers, it offers a very high number of functions and options for customizable functions. We would therefore rate the price-performance ratio as very good.

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
9.0

AdBlocker Ultimate is easy to install and can be used immediately afterwards. Even beginners should find the extra functions easy to use, as they are described in detail. Great importance has been attached to the individual settings for each user.

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.

8.2

The tool offers the function of extra privacy protection by preventing tracking and thus increasing online security.
However, it is not entirely transparent in the policies whether the data collected by the extension is passed on to third parties.

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.

AdBlocker Ultimate is a great extension for blocking ads. Ads on various platforms are removed without the user noticing. Particularly noteworthy are the various options for customizing the settings. The user can control whether the extensions should only be responsible for blocking ads or whether they should also offer support in the areas of data protection and security. Compared to other ad blockers, the additional function of blocking cookie banners stood out, which we no longer want to do without.

Overall, we consider AdBlocker Ultimate with its wide range of additional functions to be a reliable option for anyone who wants to remove advertising from their online experience.
