Writing the application code is perhaps the most time-consuming stage in the development of the application, which is divided into front-end and back-end. On the front end, the client part of the application is developed – the interface, business logic, and on the back end – the server part, which is responsible for receiving, processing and transmitting data.
There are many interface development methods, but we will highlight two main ones – cross-platform and native.
The cross-platform method uses common development kits. The application is written using the same technologies and the same language, but is suitable for different platforms. Therefore, this method is more economical both in development and in support.
The complexity of this method is that after the release of a new version of the operating system, it will be difficult to quickly update a cross-platform application. Most likely, you will have to wait for the update of the framework used.
Native development means that the language and technologies specific to only one platform are applied to the development of the application. For Android applications, for example, Java / Kotlin is used, and for iOS – Swift / Objective-C.
The native approach allows you to use the capabilities of the chosen platform to the maximum. This means that the performance of such applications is higher, they work more smoothly. Developers, in turn, can work with all the functions of the system and quickly make changes to the application when updating the OS.
However, the native method is more expensive – and not only at the development stage, but also in support.
Which approach to choose? Depends on several factors:
The complexity of the functions performed by the application;
Application speed and responsiveness;
Business processes that will be built into it.
The cross-platform approach is most often chosen for the development of test products and small applications, while the native approach is chosen for applications that are tightly integrated with the operating system and should become a full-fledged element of the business and influence sales.
It is carried out at all stages of development. It is important to remember that testing is not only about finding bugs and errors. At this stage, it is important to understand how convenient the application is to use, how intuitive it is for the user, whether it is difficult to find the desired function, check security levels, speed, etc.
Testing is divided into several stages:
Functionality – registration, user authorization, purchases;
The performance of the application and devices of different types and manufacturers;
Productivity, work at high loadings;
Security – protection against leakage or deletion of data.
Regression testing is also carried out, which allows you to make sure that after removing some errors, new ones do not appear, and unaffected parts of the code work without failures.
You should not spare any money or time for this – the deeper the testers study the application, the less likely it is to find a bug after downloading the application from the store, the higher the loyalty of the end user. It’s better for a business to have no app than an app that doesn’t work well and creates a bad impression about your services and products.
After successful testing, the work does not end – it goes to support. The team constantly monitors the smooth operation of the servers, monitors the reaction and feedback from users. At the same time, it is important to respond quickly not only to negative reviews and error messages, but also to wishes. The sooner bugs are fixed, the sooner the app store will hide negative reviews of the previous version.
We must not forget about development. The mobile app market is growing and transforming every year. In order not to lose users, you need to stay afloat and constantly update the application in accordance with new trends. So at one time, during a pandemic, restaurant and delivery applications took their bearings and quickly added a door-to-door delivery option: if the user did not want to contact the courier, he could check the corresponding box in the order.
However, it is ideal to have an idea in advance of how your application will grow. To do this, a roadmap (road map) is compiled – a plan for the development of the service for years to come. It’s good when the client already imagines what improvements and features he wants to add to the application. However, if there is no such understanding, the development team will help you figure it out and create a roadmap based on app reviews and analytics data.
Despite the apparent simplicity of mobile applications, their development is a complex, multi-stage and costly process. And the success of the finished product is influenced by a huge number of factors, from its functionality and competitiveness to its promotion and development. Therefore, before embarking on development, we recommend that you properly assess your capabilities and analyze the market. After all, the “trendiness” of a solution does not always guarantee the success of an application.
