Discuss
1

I want to make an app which sends number 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 and vice versa.

Example

Before sharing

         A                    B
        100                100
       Send               send

After sharing 10

         A                    B
         90                 110

Use firebase database with key of userid and value of the number.

When you want to transfer,

  1. read user A balance
  2. update user A balance - decrement some amount
  3. read user B balance
  4. update user B balance - increment some amount
