    the strongest bypass protection of any website blocker
  • Flexible Scheduling
    Users can schedule focused work sessions and breaks with advanced customization options, which helps in maintaining a balanced work routine.

    built-in work/break cycles with floating timer window
  • User Metrics and Reports

  • Strong Security

Possible disadvantages of FocusMe

  • Cost
    FocusMe is a paid service with subscription plans, which might be a barrier for some users who are looking for a free solution.
  • Learning Curve
    The wide array of features can be overwhelming for new users, requiring a learning period to fully understand and utilize the software effectively.
  • Potential Over-Restriction
    Intensive blocking settings might inadvertently hinder necessary tasks or access to websites and apps needed for work.
  • Mobile Limitations
    The functionality on mobile platforms may not be as powerful or seamless as on desktop versions, potentially limiting its usefulness for mobile-heavy users.
  • Occasional Software Bugs
    Some users may experience technical glitches or bugs, particularly after updates, which can temporarily disrupt productivity efforts.

KnowCSS features and specs

  • Interactive CSS Learning
    KnowCSS provides an interactive way to learn and practice CSS properties and concepts, making it easier for beginners to understand how CSS works through hands-on experimentation.
  • Quick Reference Tool
    The site serves as a handy quick-reference tool for CSS properties, allowing developers to quickly look up syntax, values, and usage examples without digging through lengthy documentation.
  • Visual Demonstrations
    KnowCSS offers visual demonstrations of CSS properties, helping users see the immediate effect of different CSS values, which accelerates understanding of styling concepts.

    The platform is freely accessible, making it a cost-effective resource for students, self-taught developers, and anyone looking to improve their CSS skills without financial commitment.
  • Clean and Simple Interface
    The website features a clean, straightforward interface that is easy to navigate, allowing users to focus on learning CSS without being distracted by cluttered design or excessive advertisements.

Possible disadvantages of KnowCSS

  • Limited Depth of Content
    KnowCSS may not cover advanced CSS topics in sufficient depth, which means experienced developers may find the resource too basic for their needs and would need to supplement with other resources.
  • Limited Community and Support
    Compared to larger platforms like MDN Web Docs or CSS-Tricks, KnowCSS has a smaller community, meaning fewer discussions, forums, or peer support for troubleshooting issues.
  • Narrow Scope
    The site focuses specifically on CSS, so users looking for a comprehensive web development learning platform covering HTML, JavaScript, and other technologies will need to use additional resources.
  • Less Frequently Updated
    Smaller niche tools like KnowCSS may not be updated as frequently as major documentation sites, potentially missing coverage of the latest CSS features and specifications.
  • Limited Real-World Project Examples
    The platform may lack complex, real-world project examples that demonstrate how CSS properties work together in practical scenarios, which can leave a gap between learning individual properties and applying them in production.

FocusMe Reviews

  1. Started using FocusMe six years ago. I rely on it heavily.

    I have been using FocusMe software on all my PCs and phones for over six years. I have a paid license. I would really like to commend the developers of FocusMe. As someone who spends more than 8 hours a day at a computer, it is easy to let it take over your life, even to the point where I found myself watching, chatting and posting even when I didn't particularly want to. I wanted to take control, and FocusMe was a really good solution. FocusMe differed from other products because it handled the entire scope of the problem: 1) lock out stuff from my kids, 2) lock out some of the same stuff from me, 3) not interfere with special internet use (like GitHub, or work related youtube), and 4) to give a whole range of solutions for partial lockout, by time, location, overall usage, multiple password schemes, etc. They do a really good job protecting the software from anyone who might trying to hack around it. There really isn't anything like it.

    ๐Ÿ Competitors: Freedom.to, Stay Focused, SelfControl
    ๐Ÿ‘ Pros:    Easy to use|Easy user interface|Strong feature set|Highly customizable|Detailed reports|Cost effective|Great customer support
    ๐Ÿ‘Ž Cons:    Configuration is repetative|Needs tweeking to get rules right|Limited trial version
  2. The Best Application for Managing Digital Distractions

    Wow! Where should I start? I've been constantly searching in these two years for finding a complete solution that could really help me manage my digital distractions and focus on my daily life routines, most applications are either not effective enough, so easy to circumvent or very resource-intensive, then I found FocusMe!

    1) It has everything I was searching for, most applications are not effective enough, some are just browser extensions, have a few options and not customizable enough, with FocusMe I can easily create very flexible plans to:

    a) Destroy bad habits and create good ones. For example block Internet at a certain time of night to help me sleep at a certain time each night. This has helped my insomnia a lot and my sleep times are getting regulated now.

    b) Block unnecessary and possible harmful contents completely. For example, it may be a personal choice but I choose to block online adult contents for most weekdays, which has helped my brain to regulate my dopamine system tremendously.

    c) Time limit other contents during work days, Contents that are useful but can also easily waste a lot of your daily time if not careful enough, like emails, news, social media...

    2) Most other applications can be circumvented easily, if you have a little computer knowledge, most of these applications are useless, but FocueMe! OMG! It goes to great lengths to make sure you stick to your plan, when you create and start a plan, you can't cheat it! You can even create punishment if you try to bypass your plan, to restrict your access more which can prevent any kind of future cheatings. It is evident that FocusMe creators really love what they do and really pay attention to details, which is what distinguishes this from most other similar applications.

    3) Some other applications are very resource-intensive, you can see in windows task manager that they swallow all of your computer resources or even slow down your web surfing/loading experiences which makes them useless, because no one wants to have a slower computer just to have an application to control his/her daily habits, but when I use FocusMe, there are no computer/web surfing slow downs and also the resource consumption is minimal which also makes this software a great choice.

    4) Last but not least, FocusMe has a superb support system, you never feel alone on your path to more success and focus, they are always there for you answering your questions and always updating the software to newer greater versions.

    Let me emphasize this point: I don't know how I could live without this application and I wished I had found it sooner! Those that are searching for applications to help them live a healthier life know what I mean if they read my explanations above. It took me two years to find you, FocusMe! I would give you 10 stars if I could!

    After all these years, I finally feel in control of my life and my time, Thank you.

  3. FocusMe review

    It just all works properly unlike other softwares. I am very happy because if I have minor troubles, customer support is there the same day to help me fix it. A lot of good locking systems that so far I haven't been able to cheat.

    ๐Ÿ‘ Pros:    Great customer support
    ๐Ÿ‘Ž Cons:    Nothing, so far

  • Build/compile/package restore times KILL my productivity
    It's called FocusMe (https://focusme.com/). I came across some years ago when it was still a simple little app. You had to manually set it to block a site and enter in a time period. I had my daily working schedule that I use now set up and I wanted FocusMe to run on a schedule as well.

  • App to track writing progress?
    I don't know of any specific app that does what you want but you can mix it up across platforms. I track all my writing time with Toggl Track's free plan and I use Google Sheets for word count. If you're looking for distraction blockers I'd recommend Forest for your web browser if you want something free, but if you're willing to pay for something more powerful I recommend Freedom or the even more restrictive...
