User needs analysis
is the most important part of the entire APP development process. It is equivalent to the status of the decision-maker in the enterprise. The success of an APP is also determined by this. . The user needs analysis here is to sort out the APP functions based on the user's requirements. Note that this is the user, because many companies require that the APP developed be used by their users. Therefore, when sorting out APP development needs, you must not only understand the needs of the development company, but also the needs of its customer groups. Finally, these requirements are sorted out and classified, and the general APP functional framework is sorted out. This process requires close communication with customers and strives to ensure that there are no doubts to avoid developing an impractical APP.

Product prototype design
在After conducting a round of user needs analysis, the sorted needs are classified, organized, and sorted into functional structure modules. At this time, the existing functional modules can be used to build a simple product prototype. A product prototype is similar to a sketch of an APP product. It shows the basic functional structure to customers. Similar APP products can be simulated with the help of product prototype design software. Confirm this product prototype with the customer. After confirmation, you can enter the next stage of development.
UI visual design
After having the APP product prototype sketch structure, UI designers begin to design the APP interface Beautify, design the layout structure according to the performance content of the APP, then color each area accordingly, draw the icons of each function menu and the design of other page elements, and finally design all APP interface renderings. During this process, we communicate with customers and design with reference to customer suggestions.
Database construction
According to the functional data processing situation analyzed and sorted out according to the needs, establish a reasonable database table structure and optimize the data algorithm , improve data processing efficiency and ensure the security, accuracy, stability and timeliness of data during the use of APP.
Server-side development
The core processing of the APP application is completed by the server-side program, and the client-side APP only Just need to send and receive data. Due to the limited hardware configuration and storage capacity of the user's mobile device, the core data processing process is performed by the server. This method is also called cloud computing. After the server processing is completed, it is fed back to the client APP. Therefore, server-side program development is extremely important, and all functions need to be developed strictly in accordance with the functions compiled during the requirements analysis stage.
iOS/Android client development
At this time, the client is developed according to the APP renderings designed by the designer, mainly to implement the code of the design renderings, and Write an interface for function calls to connect to the server to facilitate interaction with server-side data. Carry out APP development and optimization based on the device software and hardware conditions of Android and iOS, and finally develop an APP client that is consistent with the renderings.
APP program testing
Conduct a comprehensive test on the developed APP client. This test simulates the normal use of the user and In the case of abnormal use, some test data will usually be imported for testing, and the test results will be recorded. If an error occurs, it will be returned to the development stage for repair. If the test passes, it means that the overall APP development process has been completed. The finished APP application is handed over to the user for trial use. Once the user is satisfied, proceed to the next step.
Upload to the App Store
At this stage, the development of an APP has been completed. After completing the signature verification, the developed The client APP program is submitted and published to various application stores. The iOS version of the APP is submitted to Apple's AppStore, and the Android version is submitted to major domestic Android app stores.
Maintenance and update of APP
Maintain the APP after it goes online, collect user feedback information, and promptly fix errors (Bugs) that occur in the APP application. If the customer needs to update the function of the APP, it will return to the required function sorting stage for development. After the development of the new function is completed and the test passes, the update can be released.
