You have already asked this question on the Kodular community:

If you are building your app using Kodular then you should continue to ask for help there, AI2 and Kodular can be very different.

This type of app requires a transaction log that can be used to trace the money transfers and to reconstruct the current balances.

The log would be a list of lists, (a table) with each row looking like

  • 20241225, Santa Claus, ABG, $0.02

This would record that Santa Claus gave ABG $0.02 on December 25 2024

To supplement this, you would need a balance log of end of day balances by date and name.

  • 20241224, Santa Claus, 1000000.02
  • 20251225, Santa Claus, 0.00
  • 20241224, ABG, 1.00
  • 20241225, ABG, 1.02

(This should have been sorted in time order first, but I am on my phone)

This is how banks do it, to allow audits.

This app is not a money sharing or not a financial app
Iwant an app like simple users points share one user to another
Like this
I want to make an app which sends points that means just suppose user A sends 10 from his app to user B and also suppose user S has 100 number already in his app , when A sends it becomes 110 in B’s app

It does not matter if you share money or only points, the concept @ABG described is the same

You said above that you had finished with Kodular, but your aia project is built with Kodular, which is incompatible with AppInventor. You will need to create a new project with AppInventor.

This is the AppInventor community. I do not do any work on Kodular app project. As suggested, rewrite your project in Appinventor.

Where should the points originate?

Are people born with a set number of points?

Is there place you can buy points?

Is there a Government Points Printing Office?

Do points have to be mined, like Bitcoin?
