Features Tooltivity's expert score for the 'Features' aspect of each extension. | 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.
| 9.3 Todoist offers comprehensive functions for task management. Tasks can be prioritized, labeled and filtered. ![]() Another good feature is that websites can be saved directly as tasks. This can be done via the taskbar button or by right-clicking. In this way, information on a website can be added directly as a task that you want to edit or read up on later. ![]() The extension can also be used to mark tasks directly as completed. Other features like collaborating on projects and tracking progress with personalized productivity trends add further value. Some of these advanced features of the application, such as customized templates and advanced reports, are available in the paid plans. Winner in this category |

Design Tooltivity's expert score for the 'Design' aspect of each extension. | 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. | 9.5 The design is clean and intuitive, making it easy to navigate immediately. The interface can also be visually customized to suit your needs, but these are not overdone. The option of color-coded priority levels and project labels also helps with organization.

Value for Money Tooltivity's expert score for the 'Value for Money' aspect of each extension. | 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. Winner in this category | 9.0 The functions of the Todoist extension are free of charge. The free functions of the Todoist application should also be sufficient for most users. For users who want to use functions such as reminders or additional view options, the price should also be reasonable. With an annual payment installment, $4 per month is reasonable in our view. |
Ease of Use Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 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. ![]() Winner in this category | 9.0 In our test, we had no problems with the installation and the first steps.

Conclusion A summary of our findings and final thoughts for each extension. | One Sec is a tool that encourages mindful browsing by introducing a pause every time you want to access a distracting website. | Todoist is a great option for task management. We really like its simplicity, which is likely why it has become so popular. While some modern tools may offer more features, Todoist is one of the best choices if you’re looking for a solid, beautifully designed to-do list. Still, we noticed some performance issues. The extension takes longer to load when working in environments with a bad internet connection. It’s not a dealbreaker, but something to be aware of, especially if you often work in places with poor internet. Overall, Todoist is a strong choice for anyone seeking an easy-to-use and powerful task manager, though its speed and offline capabilities could be improved. If you would like to test Todoist yourself, you can use our code to get the Pro version for 2 months free of charge. https://get.todoist.io/mgs7dk |
