Online and mobile banking
Online banking, also known as virtual, internet or e-banking, is an electronic payment system that enables customers of a bank or other financial institution to process a wide variety of financial transactions through the bank's website. Since online banking is heavily dependent on Internet access and its prevalence, the first e-banking services emerged in New York in the early 1980s when it was known as "home banking". Today, account management via online banking is in great demand.

While e-banking has been around for some time, mobile banking is a relatively new service from financial institutions. Due to the growing popularity of smartphones, more and more banks are developing their own mobile banking applications. In 2015, 90% of US bank customers had used mobile banking to check their account balance or recent transactions in the past 12 months. Some banks are working hard to develop new tools in addition to the traditional bank account management services available through their smartphone apps.

I completely agree with you. Nowadays, it is essential to have a personal application. Or at least a website that would be adapted to the size of the smartphone screen.
The consumer has become so lazy that he does not want to understand bulky sites with tons of information. He wants beautiful apps with a couple of attractive buttons.
So when my friend told me that he was launching an online clothing store, I immediately told him that he needed to have an app development iOS. And I advised him of a company that makes good and high-quality applications.
