Abstract

1. Introduction

Today in the world, there are a considerable number of mobile app development companies so each customer can choose a developer to his taste among top app development companies. However, it is worth remembering that adhering to design and coding standards while developing applications is fundamental. This is important for improving project efficiency, ensuring high performance, reducing the risk of project failure, simplifying maintenance, improving security, and providing easy debugging. Therefore, ensure that the development team that builds your app follows the design and coding standards for producing quality code. In this case, you will receive a quality product in demand.

Mobile development in its current sense arose in the noughties, after the release of Java Micro Edition and WAP (Wireless Application Protocol), a stripped-down version of Internet access. Then, people wanted to have fun on the net, check e-mail, chat on ICQ - do everything they do on ordinary computers, but from their mobile phones.

There were few developers, and a different program version had to be written for each phone model. There was also no convenient distribution system, although the idea of an application marketplace was put forward by Steve Jobs back in 1983 at an international design conference in Aspen.
