TickTick

TickTick is a complete virtual diary which you can use to comfortably organize all your daily tasks. With its elegant and comfortable interface, you can keep track of all your daily tasks: appointments, meetings, commitments, work, etc.

Writing anything down on TickTick is easy and convenient. It is also very easy to assign a specific date to any task, or to set a reminder so that you don't forget. Once you have completed a task, all you have to do is check it off.

In the configuration options of TickTick you can customize the appearance of the interface. By default you will see the blue theme, but you can choose from many other different colors. Other options include protecting the app with a pattern lock.

TickTick also has an option to create collaborative task lists. This is especially interesting if you share projects or activities with other people who also use the program.

TickTick is a good app for Windows that allows you to note down your pending tasks. Its main strengths include a simple, elegant interface and a good number of customization options. What's more, the fact that you can link the information with other Android or Mac devices gives this program the multiplatform factor that is also something to highlight.
