If you have used the “Clockr” widget, you may be familiar with that theme. XDA member arctu has developed a widget with the same theme called “Calendr”. The widget is minimalistic and shows your next upcoming event along with its time. As quoted from the OP you can see how minimal it is:
Follows the style of clockr, only needed information is shown. It shows the upcoming events within 1 week range, and most importantly, it only shows 1 event.
The widget refreshes once every 30 minutes to keep you updated and uses minimal memory and CPU resources. If you want to learn more and try it out yourself, then check out the discussion thread.___________________
