Could anyone send me a simple background app that counts from 1 to 100 when the app is closed

You do not need something running in the background for that. .

Let's assume, you like to increment the counter every second... do it like this: press the start button and store the start time in TinyDB and increment the counter in a Clock.Timer event
Additionally in the Screen Initialize event read the start time from TinyDB and calculate the elapsed number of seconds by calculating current time - start time and set that as counter

In this case you should first learn the basics...

A very good way to learn App Inventor or Kodular is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps
How to do a lot of basic things with App Inventor are described here: How do you...? .

Also do the tutorials Tutorials for MIT App Inventor to learn the basics of App Inventor, then try something and follow the Top 5 Tips: How to learn App Inventor
