SpiderBasic

I have an app that I always run in the background, and all it shows is the current day day, date and month on the top of the screen.

I Would much prefer to write my own Android app to do that.

Is it possible to have a SpiderBasic app run in the background on top of all (or as many as possible) other running apps on the phone, to display the "SAT 08-03" for example like this app does today?

basically you want to do a "widget"
Which is not possible using native commands
you can use cordova plugins though, like ACE.

but need more "deep programming"
