Trello Reviews

  1. A handy tool for planning

    Trello excels as a task planning tool, and I appreciate its user-friendly interface, especially when using it on a smartphone. Its mobile app is incredibly convenient, allowing me to stay organized and connected on the go. I appreciate how it streamlines collaboration without unnecessary complexities.

  2. Been using it for over 5 years! Super effective!

    Incorporating Trello into my daily workflow has been a game-changer. It is an incredibly intuitive and versatile tool that has significantly boosted my productivity. What I particularly love about Trello is the visual aspect of its interface - the board and card system makes it easy to visualize my tasks and progress. The ability to create different boards for different projects or areas of work helps to keep everything organized and easy to manage. Adding, moving, and categorizing tasks are just a drag-and-drop away, making it straightforward and efficient. The flexibility to customize each card with due dates, labels, checklists, attachments, and even members has been beneficial in tracking the status of various tasks and deadlines.

    he collaborative features are another huge plus. Sharing boards and tasks with colleagues, and being able to comment directly on cards, makes team projects and communication a breeze. On the go, I have found the Trello mobile app to be just as user-friendly and functional as the desktop version, allowing me to stay on top of my tasks no matter where I am. Overall, Trello has proved to be an invaluable tool in managing my daily tasks and enhancing productivity. I highly recommend it to anyone looking to streamline their workflow.

    A Great Collaboration Tool, But There Are Better Options Out There

    I have been using Trello for a couple of years now and I must say, it's a great tool for organising tasks and collaborating with team members. It's simple to use, has a nice interface, and the mobile apps are great for on-the-go productivity.

    One of the best things about Trello is its flexibility. You can use it for almost any type of project, whether it's a personal to-do list or a complex team project. The ability to create multiple boards and add unlimited cards and lists makes it a great tool for keeping track of everything from the big picture to the minute details.

    However, while Trello is a good tool, I don't think it's the best option out there. For one thing, the free version is quite limited in terms of features and functionality. You'll have to upgrade to a paid plan to get access to things like integrations, power-ups, and more. Additionally, I've found that Trello can be a bit slow at times, especially when you have a lot of boards and cards.
