So here, you’ll find all that you need to know about mobile app development. Anyone who isn’t a mobile app developer but wants to learn more about the subject is encouraged to read this guide. It doesn’t matter whether you have a brilliant mobile app idea, if you’re the founder of a start-up, or if you work for a corporation that wants to experiment with new technology. You can hire best app developers UK for app development, but this guide will summarize the many aspects and concerns involved in app creativity for whatever you are.
So what does mobile app development mean?
Mobile app development is simply the process of making software that runs on a mobile device, and a typical mobile app connects to a network to work with other computers.
Here is the guide to guide to mobile app development in 2021:
Mobile App Development Stage 1: Plan
The first step of Mobile App Development includes defining the app’s purpose, audience, and success metrics.
1- Define the app’s goals.
A mobile app should be helpful and solve problems for the user. Ask yourself what issues your app will tackle and how you will benefit from it.
2- So who and how many is your target audience?
Building an on-demand mobile app requires knowing your consumers. Your persona’s demographics, motives, behavior patterns, and objectives should be researched. It would help if you had in mind the user lifecycle and its characteristics, whether your target audience is iPhone or Android. In this manner, you may design user personas that assist you in understanding the app’s users’ objectives and limits. Thorough research clarifies and solidifies your app’s concept.
3- Observe the opponents
A careful analysis of your competitor’s app can help because it lets you identify missing features that you can add to your own to make it stand out.
4- Choose a mobile platform
After determining the target demographic, choose between iOS and Android. The app may be built in two ways:
Suppose you want to create a high-performance app with a rich user experience and complex logic that can be easily upgraded and expanded with additional features in the future. In that case, native development is the way to go.
Cross-platform development if you only have a limited time to test your hypothesis and idea in the app market or if you need software products or services that work across multiple operating systems. It’s also not very expensive since you can make a single app for both platforms.
The plan stage’s output:
- Know the app’s aims and target demographic
- Choosing a mobile platform
- Creating a project roadmap with functional tech considerations
Mobile App development Stage 2: Design
A product owner, project manager, business analyst, 2–3 app developers per platform (Android and iOS), backend developer, UI/UX designer, and 1-2 QA engineers are needed at this stage. After forming your team, you may start designing.
In the design stage, four steps:
1- Defining needs
The team will review the first data before asking more detailed and contextual questions at the client session.
2- UX design
The team evaluates and categorizes all customer information and fills up any gaps. We plan the project structure, user flow, happy passes, and edge cases. After the customer signs the NDA, we move to the UI stage.
3- UI design
It’s crucial to consider the client’s preferences and the target audience. After the primary screen designs are approved, we can construct the style guide and render the remainder of the displays. It’s crucial to follow the client’s brand book or corporate style.
4- Upkeep and testing
The designer’s job isn’t done when the developers have all the app prototypes. Throughout development, the designer also works with the project team to clarify tricky logic, structure, and balance between beauty and technological feasibility. The designer must also verify the finished product for design and concept conformity.
These processes enable creating a high-quality app tailored to the customer’s company and target audience.
The design stage’s output:
UI/UX final development plan – wireframes, ideas, prototypes, and user testing (source design files, project specification for developers in Zeplin, Adobe XD, Figma, InVision)
- A guide (specification of fonts, sizes, styles of elements, and their states)
- Clickable application prototype (optional, if the client requested it)
- Continued development team support
Mobile App development Stage 3: Growth
The steps of the development process are as follows:
- We choose application architecture based on functional needs such as orientation, flipping, business logic, and more. App architectures for Android and iOS include MVP, MVVM, Viper, Redux, etc.
We may pick the best match for the project based on the backend technology.
- We assess whether the backend will support the app’s functionality when the graphics and non-functional needs are evident. Apps for iOS and Android have distinct needs. Backends may be put up in two ways:
AWS Mobile Hub, CloudKit, Kinvey, Parse, and other SaaS backends for basic app MVP
• A bespoke backend if you expect the mobile app to develop features and users.
- We chose the frameworks, libraries, and off-the-shelf solutions. Frameworks like DI and Binding let developers write faster iOS and Android code. Concerning the project’s functionally specialized frameworks:
• For Android – Play Services (Maps API, Places API), payment gateways, social integrations, etc.
• CoreLocation, HealthKit for iOS
- The team may be involved in API design. Create an API that enables your application to interface with the entire system or with third-party applications if you already have one.
- We may create our database and draw diagrams to find out the network models.
In addition, as specialists, we can advise business analysts and designers on the system’s constraints and ideal UX/UI solutions.
- The team configures CI/CD repositories (by default, projects are automatically built through Gitlab pipelines)
The development stage’s output:
• Testing app ready
Mobile App development Stage 4: Testing
Application testing is crucial and may save money early in the mobile app development process.
There is a requirement for testing for:
- Usability
- Compatibility
- Security
- UI
- Performance.
There are three forms of testing:
1- Performance testing
Performance testing checks how quickly a system or element responds to a load. It can also check scalability, dependability, and resource usage. Performance testing tells you how effectively your app reacts to user requests, how quickly your screens load, and whether your app is too big.
Performance test directions:
- Load testing to assess an application’s performance under load.
- Excessive or disproportional load testing to assess system reliability
After your app passes the performance tests, you must test the API and backend by simulating the maximum number of concurrent users. The app should be able to manage huge loads and still run correctly.
2- Security testing
Security testing is critical in mobile app development. Mobile business applications must exploit any possible flaw.
Personal data such as date of birth, residence address, private emails, passwords, credit card data, bank account numbers, order numbers, etc., are examples of critical user data.
This is a method of assessing a mobile app’s security that involves measuring its protection efficiency. They test the application for weaknesses, technical problems, and vulnerabilities.
Basic rules:
- Store sensitive user data on a secure platform.
- Never keep sensitive user data in code or resources.
- Only use well-established, current, and well-known cryptographic algorithms.
- Test your mobile app’s data input forms for data leakage.
3- UX testing
Usability testing should be done throughout software development. Thus, numerous issues may be recognized before or during interface design.
You can use them as usability testing to evaluate a product’s particular features, assess the user’s overall perception of the app or design, or compare the app to similar products.
Beta testing is critical to verify that your program runs smoothly and is pleasant to use. Outside users evaluate an app’s beta version and offer genuine feedback to understand the usability flow or potential concerns.
Beta testing benefits:
- Real-world testing and bug fixing before release
- Fewer troubles and complaints after final market release
After internal app testing, the team is ready to release the beta version to the market.
The testing stage’s output:
- Fully tested functionality, backend, and app
- Functionality spec
- Full code
Mobile App development Stage 5: App Launch and Support
Most apps have priority features in the initial release, with additional capabilities in later editions.
The app is now ready for market release. However, keep in mind app stores’ regulations for approving and validating mobile applications. After submitting your program to the Apple App Store, it can review for quality and compliance with Apple’s iOS development requirements. Software reviews on Google Play are different from App Store, but your app may be in the market within hours.
Following the app’s submission, it’s critical to maintain trends and update functionality in response to audience targeting demands and assess user input for future upgrades.
