What is it about?

This is an application for your phone and it is not an official one. It is made by a group of developers who want to help their fellow developers to be more productive.

What does it do?

This application shows you the number of the week in your phone’s notification bar. It can be useful to you as a developer or a project manager.

You can see the number of the week or the day of the week and year in the notification bar.

You can choose between the system with Sunday or the ISO-8601 system with Monday as the start of the week number calculation.

It has 12 handcrafted icon styles, including clean system or fancy bright colors. Making sure you have the week number visible, not getting it blurred by other notifications.
