DropTask

There is a good reason a lot of people rely on post-it notes to organize their activities and remember certain events, as it is much easier to visualize your workflow when not simply viewing everything in text form.
DropTask is a cross-platform application that aims to provide you with a more intuitive method of managing your activities, as it enables you to sort them into categories and projects, as well as collaborate with others easily.

Add your tasks to a virtual canvas and visualize your workflow

The application’s most distinguishing feature is the canvas that can be used to organize activities quickly and efficiently. Once a task has been added, you can move it across the canvas freely, place it in a certain category and keep track of its status and importance at all times.
DropTask allows you to filter items based on keywords, assignees, importance, tags, assignments and more, making it very easy to find the tasks you are looking for.
It is also possible to map out your project using Kanban-style boards to represent the various stages, as well as view your tasks in a simple list.

Convenient service that can be accessed from a wide range of devices

It is important to note that a DropTask account needs to be created online in order to use the application, and you can then log in from the desktop program, OS X, Android and iOS apps, as well as the web interface.
Because your data is stored in the cloud, you can access your projects and tasks from any location and multiple devices, making it much easier to complete your assignments on the go.

Features a streamlined UI, but could be improved in certain respects

The user interface is essentially identical to that of the DropTask web app, and most users should find it to be quite intuitive. However, the program is launched in full-screen mode automatically, and it cannot be sent to the system tray.
Also, it is worth noting that performing certain actions, such as managing your profile, still requires you to access the service through your web browser.
Overall, DropTask is a modern task management solution that makes it easier for you to visualize your workflow and stay on track of your projects. It is quite versatile, as the service can be accessed from numerous devices, but the desktop application could use some small improvements.
