Generally speaking, the development process of app software can be roughly divided into three stages, namely, the early stage of app development, the middle stage of app development and the late stage of app development. Among them, the pre-development of app includes pre-communication in the flow chart of app development, app demand assessment, app planning, even visual design and ui design. Mid-term development of app means that app is a development process, including front-end production, back-end production and technical development of app. The post-development of app refers to the debugging and post-maintenance of app.
Of course, from the user's point of view, the flow chart of developing an app should be like this, which is divided into seven steps, namely, entrusting an app development company to make a mobile app, providing an app development plan, knowing how much app is developed, confirming the app software development and signing a contract, and the app production company providing an app development report, formally developing the app, and finally developing the app.
