Simle Widget to show the number of current week. It works with both types of calendar (US where first day of week is Sunday and ISO where fist day of week is Monday).

Features:
- Show current week in up to two formats (US & ISO)
- Today Widget, no need to even open the app
- You are allowed to set the theme colour that affects both the widget and the app.
- Most simplest UI

This app will not connect to your calendar and fill it with useless data.
