How to Use This App Development Checklist?

Before knowing the usage of an app development checklist, you need to select your processing phase. For every phase, you are required to answer certain questions, and some of the suggestions with examples are thoroughly explained below:

Understanding the App Development

This section identifies the objective of your application and defines the problem that it is supposed to resolve. By defining the objectives and goals clearly, the mobile app development process can be aligned with both your company’ s goals and your customers’ (users’) needs. Thus, avoiding the use of unnecessary resources and the development of features that do not meet the user’s needs.

You need to ask certain questions before your app development process checklist starts, such as:

• What is your target audience?
• What kind of issue are you solving, or what utility are you going to serve?
• Is there any firm solving the same purpose online or offline? (Thorough market research will be required for that.)
• Who do you consider your competitors to be, and how long have they been surviving in the market?
• What kind of app features are they using?
• Check out the reviews regarding their apps across different platforms and see what people are saying about them.
• Do you have information regarding the particular business model that the company has selected, as well as their monetization strategies?
• What is the business application that you are planning to use, and do you believe that this will have a positive impact on your business?

Examples and Potential Options:

• Business Application: Expense Management, Teamwork, and Inventory Control.
• Consumer Application: Social Network, E-commerce Platform, and Fitness Tracker.
• Hybrid Application: Apps that provide both Consumer Engagement and Business Functionality (e.g., Loyalty Program Apps that provide Analytics to Business Owners).

Applications that provide a combined offering of business and consumer engagement capabilities. Establishing your Core Value Proposition for this application at this stage will serve as your guide throughout the process.

Choosing the Right Technology Path

At this stage, opting for an effective tech-stack as well as platform, along with detailed architecture, is critically important. It is essential for the scalability, performance, and maintainability of your application. Therefore, it is necessary to ensure that your application is developed using a sound infrastructure, which can expand and scale to accommodate the growth of users and future changes.

Here you need to choose considering following:

• Which platform do you choose, Android, iOS, or both?
• Will your app be Native or Hybrid?
• Does your app require cloud-based infrastructure or not?
• Is your app able to integrate with the features of the user’s device?

Options and Examples:

• Native Applications: These applications are separately developed for iOS (using Swift) and Android (using Kotlin). Typically perform better and integrate more completely with device features.
• Cross-Platform Mobile Apps: Built with one codebase that can run on many types of phones (React Native, Flutter, Xamarin), generally take less time to make than native apps, but because they are built on one codebase, they run slightly slower than native apps.
• Progressive Web Applications (PWAs): Execute within the browser environment while providing an App-Like Experience. PWAs are best suited for applications that are built for multiple platforms without incurring the high Development Costs involved.
• Back-End Choices: Cloud (AWS, Firebase) and On-Premise Server-based Solutions up to your company’s scalability and compliance needs.

Architecture dictates scalability, performance, and long-term maintenance costs. Here’s short summary for better understanding: 

Choosing the right technology path will permit your app to scale with your growing user base, as well as keep pace with the changing business goals of your company.

Designing Screens Users Will Enjoy Using

The success of your application is dependent on the design of its interface. The layout and the overall aesthetic of the screens within the application play a huge role in increasing user engagement and keeping users engaged with your application. Your application’s interface should be simple to navigate, easy to use, nice to look at, and recommend that users continue to utilize your application.

Some of the questions related to app design are as follows:

• Is your wireframe ready?
• What kind of app orientation will you have? Will it be a Landscape or a portrait?
• Does your app promote easy transitions from one orientation to another?
• Have you finalized your benchmarks?
• Does your CTA button stand out from the rest of the elements present on the app?
• Have you checked the transitions between the screens?
• Are your design elements perfectly inline with the culture of the region where the app is going to operate?

Some Examples and Options:

• Golden Path Mapping: Can a user reach their goal (e.g., “Checkout”) in 3 clicks or less?
• Wireframing and prototyping tools: Figma, Adobe XD, and Sketch are some of the key suggested tools. .
• User experience (UX): Usage patterns, such as bottom navigation bars for commonly used elements and swipe-to-action gesture support for users, offering them more of a convenience.
• Micro-interactions: Are there haptic or visual cues for every user action?
• Onboarding screens: These should provide a simple transition to full usage of your application, with minimal app development steps to sign up, and provide contextual in-app help delivered via tutorial.

When you design your screens well, you will have less friction and will allow users to continue using your application.

Setting Clear Development Standards

Establishing the right set of standards while developing your choice of mobile application is crucial. Standards that govern the code of development and issues related to different versions are required to be looked upon. As a part of this, having a quality assurance system ensures certain quality is there during the time of development. With certain ways of communicating with your fellow team members, you will develop less confusion, which will then assist you in making effective collaboration and communication, ultimately leading to rapid development of your mobile apps.

Here are the questions you need to ask:

• Will we develop our mobile application in-house or partner with an outside contractor?
• Do you plan on taking advantage of the expertise of a professional mobile app development company? If yes, where?
• Are you utilizing an outsourcing firm with a national or international location?
• Do you have the required team and expertise, if planning for an in-house operation?
• Have you estimated the costs associated with your entire development process? And which stage requires the most expense?
• How long will it take to begin an app’s creation until it is available for download?
• What development approach are you implementing, either iterative, agile, or waterfall?
• Have you looked at the progress of your backend development of the app?

Essential Elements of These Standards Include:

• High Quality Code: In an effort to ensure high-quality code, it is important to maintain a well-maintained code base.
• Version Control: Utilize either Gitflow or trunk-based development; employ basil and lint analysis tooling; establish a strong review system by peers; and enforce SOLID standards within your organization.
• Documentation: It is essential to develop API documentation, create internal wiki pages for your organization that set standards for code comment formatting, and establish documentation processes.
• Workflow: An agile or scrum-based workflow will allow for better closure cycles and continuous feedback to drive improvement.

Establishing Clear Standards while ticking off your app development checklist will minimize miscommunications and ensure consistency and quality as your team grows.

Making Sure the App Performs Under Pressure

Performance testing is done for confirmation that the app will behave predictably under certain conditions, such as those with heavy traffic, slow networks, or resource-intensive periods. Performing mobile applications are less likely to crash down, be slow in responding, or make for a bad user experience due to high loads and technical difficulties.

To further improve performance, the following can be asked:

• If you know how your app is going to behave in certain events like low storage, low battery, less network coverage, or Airplane Mode?
• Does your app provide a web service?
• Does your app have a server-side component?
• Is your app scalable vertically or horizontally?
• Are you able to get notification of app crashes in real time?

Examples and Options:

• Load Testing Tools: For e.g., JMeter and LoadRunner are the two suggested tools.
• Optimize Your Site: Use Lazy-Loading to improve load time & caching for repetitive data, as well as optimizing your queries to your database.
• Offline Functions: Store data on the device until you have a network connection again.
• Battery and Memory Management: Limit Background Processing and Optimize Animation for Users of Your Application.

Applications with high-performance standards are likely to generate repeat users and altruism rather than poor public-facing reviews.

Protecting User Data and App Integrity

Implementing secure data privacy practices (such as authentication methods) and conducting regular assessments of vulnerable software ensures compliance with applicable law. By implementing good security, users can feel safe using your software, which builds trust in your app.

For this, you need to answer further questions presented below:

• Have you checked for a secured sockets layer attached in your app project?
• Is your app implied with two point user authentication in place?
• Have you prepared a list of trusted members who will have access to your app’s internal operations?
• Will there be sub admins?
• Are your payment gateway systems working appropriately?
• Does your app comply with industry standards of security like HIPAA or PCI DSS?

Best Practices Include:

• Authentication: Utilizing OAuth 2.0 and Two Factor Authentication.
• Encrypting: Using AES for Data that is at Rest, HTTPS/TLS for Data that is in Transit.
• API Security: Rate Limiting and Securing Endpoints.
• Compliance: Compliance is mostly industry-dependent (GDPR, HIPAA, PCI-DSS, etc.).
• Regular Audits: Pen-testing and Vulnerability Scans are all ways to ensure that your users are protected.

Testing Before Users Do

You must conduct multiple Application Testing at each phase, such as Functional, Usability, Performance, and Security, prior to releasing it to your users to Find & Fix Bugs. This will help you to ensure that there are no bugs glaring at you, thus, helping to reduce future risks. Moreover, this will lead to fewer malfunctions and therefore greater user satisfaction.

While testing, you need to look at the following:

• Does your app perform the same or differently on various devices or OS versions?
• Has your tech team tested your app and ensured it’s running smoothly?
• Have you tried your app with real and non-technical expert users?
• Have you verified your mobile app’s location strategy?
• Is your app ready for the next device update?
• How is your app going to respond if it requires it to be scaled to the next OS update?
• Is your app ready for undergoing certain tests, such as QC testing, User Acceptance testing, and Unit testing?
• Do you have any test plan in place regarding that?

Examples of different types of testing conducted are:

• Unit Testing: Verify that individual functionality works as intended by the developers.
• Integration Testing: Verifies that the functionalities of various components present in the app work well together.
• UI/UX Testing: Validates that the design has good interaction and is easy to use.
• Beta Testing: Allows for User Feedback prior to launching the App to the public.
• Security Testing: Required to test for Potential Vulnerabilities.

Testing verifies that an app is usable, reliable, and secure, which results in fewer negative reviews and less app abandonment by users.
