Why to Run the Conversion: Top Reasons

- The significant difference between app lifespans;
- The significant difference in-app screens lifespan;
- The significant difference in methods of data access.

Key Differences to Pay Attention within the Conversion Process

1. The Fragmentation of OS Version
The operating system gets updated almost all the time. Thus, you need to be ready to assure device compatibility with your application. Users do not try to change their devices to get a new app. It means the app must be optimized to support the newest OS versions.

2. Size of Device
You need to take into consideration the size of the device. Consequently, pay attention to the screen size to assure users’ best experience with your application.

3. Navigation and Buttons
The way users interact with the applications they install becomes quite typical with time. Therefore, you need to pay attention to this factor when converting your application. Make sure to provide a convenient service for users.

4. Characteristics of programming languages
When convening your application, you must translate the code. All the programming languages’ characteristics must be checked and evaluated, including rules, semantics, syntax, and algorithms. Remember, two platforms have different programming languages. IOS apps are built on Objective-C and Swift when Android apps use Java and Kotlin. Be ready to check every detail of your app's new version before a launch.

The Detailed Conversion Process Explanation

1. Evaluation of the app’s requirements and functionality
The conversion process is quite complicated whether you know how both platforms operate or not. You need to plan it in detail in any case. Every, even slightest, detail of the conversion process must be taken into account. Make sure first to gather all the available information you can get about the chosen platform requirements and specifications. Further, you must gather all the available information on your application. It includes codes, design, and other specific details. Once you learn enough information about the app’s peculiarities, you can find some technical detail needed to be changed to meet the platform’s demands.
Once changing a mobile platform, the entire project must be divided into two categories – business and technical details. Thus, for the process to be successful, you should hire Business Consultant and Software Architect.
When hiring specialists, think through your next actions:
- Optimization and improvement of the application;
- Drawing a new working business plan;
- Reviewing and confirming compatibility;
- Selecting among a wide variety of ways to succeed (in-depth core and design review, marketing analysis, mind-mapping, etc.).

2. Optimization of the app’s design due to the new platform demands
The new application must be developed from scratch. Therefore, every design detail and interface must be modified, as well. It is a completely wrong strategy to copy every detail from one app version to another once.

  • Used Design Patterns: Material and Flat Design
    Both Apple and Google have unique design patterns that differ a lot. Once converting your app from Android to iOS, your best option is to use material design. When vice versa, the flat design pattern must be chosen
  • User Interface Design
    Android and iOS applications have drastically different user interface designs. They have different native fonts. When Android uses Roboto, iOS prefers San Fransisco. Your selection of the correct fond is very important for the entire process.
  • User Interface Mirroring
    The mirroring of your content is also an important issue. For instance, you must assure your app uses the right to left language when dealing with Arabic or Hebrew. The content should be displayed properly, depending on the country it is shown.
  • Managing Design Changes
    You need to plan all the design changes before starting a conversion process. You should deal with all details, placing a required design into a code. The correct resolutions should be chosen for every particular version of an app. Once converting to Android use hdpi, mpdi, and xhdpi/xxhdpi resolutions. In a case with a new iOS version, use .pdf.

3. Customization of the new platform’s architecture details and coding
The coding and design are two equally important issues when you convert your app. The code must be written from scratch as the same design should be unique. You can gather information from your previous app version’s libraries. Still, once writing an original code for an app, you assure full compatibility. Sometimes, you need to replace and change certain details to suit the functionality.
You should always focus on the related works when building your application. Once you are done with the code, it is important to check and test its functionality before the launch. The system’s backend must be checked as well to always keep an adjustment opportunity. It can also be wise to review your code from time to time to assure a smooth app’s operating.

4. Assurance of the ideal app testing and app store launch
You can launch your app only once it is carefully tested. This is the only way to meet the market’s demands. You should assure the top quality of the offered application. It means you need to hire a quality assurance team to test your app’s functionality and navigation.
Once proceeding to the app testing, you may need to accomplish the next processes:

  • Control and functional testing;
  • Security and access testing;
  • Performance and load testing;
  • Usability and validation testing;
  • User acceptance testing.
