Help with an App similar to the WhereIsTheBus? App

Hi guys.

I need help creating an App similar to the WhereIsTheBus? App.

The catch is, I want multiple Technicians to report their location (With a Tag to say who the Tech is on the Map) and multiple clients to "Track" the Tech who is assigned to them at that moment.

Something similar to Uber Eats or the Uber app?

I have no idea where to begin with this.

Any and all Help will be much appreciated.

A tutorial showing how to do something similar is
How to broadcast a GPS location and share the information on a map with others in real time..CloudDB The example uses the MIT CloudDB. This could be replicated using a Google Sheet.

A method showing how to track multiple individuals using a CloudDB is

Social Distancing ... a CloudDB / Location Marker Tutorial The main parts of this example seem pretty close to what you want to do.

Possibly the above links. What have you tried?
Here are possible parts of the solution:

Here are some resources to help you learn to use the AI2 tools. A very good way to learn App Inventor 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 http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles

How to do a lot of basic things with App Inventor are described here: http://www.appinventor.org/content/howDoYou/eventHandling .

Also look here http://kio4.com/appinventor/index.htm and here http://www.imagnity.com/tutorial-index/ for more tutorials.

The only thing I tried to have a look at was the WhereIsTheBus? blocks, But can't seem to figure it out.

I will try what you suggested and give feedback and or ask more questions if need be.
