Explanation: Sometimes when we help others they may do a favor for us in the future, it’s not about if we want to help them. We help them because we know it’s the right thing to do, even if they do nothing for us in return. Helping people means helping yourself because when we help people when they need it, then they help us when we need it. Of course, not always because sometimes people don’t help us in return. Helping people because you want help or some reward in return is a selfish activity. So it’s better to help others even if you get nothing in return.
If your referring to apps that help others donation, hospital, shelters, etc. Then I believe the purpose of those apps is to help those people in needs, whether it is animals going extinct, children in need, or sick people.
