Building a successful app takes more than luck. It requires smart strategies that work. In the table below, you’ll find key approaches to app development, why they matter, and real examples to guide you.

A Quick Overview of How You Can Validate the App Idea

We understand that letting your inventive ideas flow is appealing. Still, it’s also essential to explore other ideas on how you can improve your application.

Do not jump in without first testing the waters. Make a list of all the possible ideas you have. It expands your horizon about startup possibilities. It also gives you enough clarity to decide which concept to follow.

You say to yourself and are ready to implement it. But then, you hesitate and are not sure if the idea is worth pursuing. The main thing you should understand if you are determined to create your own startup is that you won’t know if your idea is worthy or not until you go to market with it.

And if you see that there is no potential in your current idea, you will need to propose a new hypothesis for validation.

And iterate until you find an interesting, scalable, and hard-to-copy business model that appeals to investors.

After you’ve established a well-versed vision, you’ll need to document your idea. Offer as much information as possible. The documentation will ensure that your developers get your idea and create the exact mobile app you desire.

As an option, you can use wireframing tools to visualize the killer features and workflows. There are many tools to try. We use Balsamiq in SpdLoad. You won’t have any trouble locating one that you’ll like to give a shot.

Another suggestion is not to dismiss other possibilities. Recognize that there is always room for improvement. Brainstorming sessions with your team can lead to innovative and unexpected results.

The famous Figma started as a drone company. But numerous and continuous iterations of product development helped them become the top tool for many designers. We often use it when providing our UX/UI design services.

The Building Phase

The next step in the app development process is the development phase. This phase is where your concept takes shape, and choosing the right team makes all the difference.

To launch your mobile app startup, you’ll need a team that understands your vision and knows how to bring it to life. You have two main options here: build an internal team or outsource development to an experienced app builder.

Here’s a quick comparison to help you decide which path fits your startup best:

If you’re just getting started and want to move quickly, partnering with a trusted app builder can give you a major advantage. But if you want full ownership of every step, building an in-house team might be worth the extra investment.

No matter which path you choose, the key is to work with people who understand your goals and can build a product that users actually want.

Project Planning

Planning is one of the most important steps in the mobile app development process. It sets the foundation for everything that follows and helps you avoid costly mistakes later on.

The goal is to align your vision with real market needs and create a clear path forward, based on facts rather than guesses.

Phase 1: Research

Before you jump into building your app, take time to explore the opportunity. What problem are you solving? Who else is solving it? What makes your idea better? You need research, irrespective of whether your targeted audience is an executive team or a client outside your firm.

Phase 2: Workshop

Once you’ve gathered enough insights, it’s time to run a discovery workshop with your app development partner or internal team.

This workshop brings everyone together to:

• Define goals and success metrics
• Map out the user journey
• Prioritize core features for the MVP
• Clarify technical requirements

This phase ensures everyone’s on the same page before app design or development starts.

UX/UI Design

“Design is not just what it looks like and feels like. Design is how it works.” – Steve Jobs

The exquisite design with which the apps are developed is the most crucial feature. It lets you conceptualize and improve on your app’s UI (user interface) and UX (user experience) design until you have a finalized template for the developers to build.

The role of UX

UX design focuses on how users feel when they interact with your app. It is about creating a smooth, simple, and enjoyable experience, from the first tap to the final screen.

A good UX means the app is easy to use, intuitive, and solves the user’s problem without frustration. If users struggle to navigate or find what they need, they’ll likely delete the app and never come back.

The role of UI

When we talk about interface design, we’re not only talking about buttons and navigation menus. It’s far more than that. A well-designed interface helps people understand what to do next without thinking too much.

In short, UI is about form, and UX is about function. When combined, UX and UI can create advanced product usability.

Coding and Testing

This is when you choose the right tech stack, build your team, and continuously test to ensure everything works smoothly and meets user expectations. Let’s dive deeper into each process.

Define the team structure

Determine which specialists you’ll need and the number required. The development team is not just specialists with coding skills. You may also need:

• Project manager
• UX/UI designer
• Mobile developer
• Backend developer
• QA tester
• DevOps (Check out our DevOps services to learn more about our DevOps practices and tools.)

Development of an MVP

Developing an MVP in business is fundamental to your success. An MVP has proven to be the go-to solution for mobile app entrepreneurs. It determines whether applications meet the requirement or need a redo. Also, the cost of developing an MVP is less than a full-scale application. This approach allows you to test the genuine usefulness and importance of your hypothesis/business model:

The development of an MVP is literally the technical side to app building. Let’s take a look at the coding details.

Native vs Cross-Platform App Development

One of the most important decisions when building a mobile app is whether to go native or cross-platform. This choice impacts your tech stack, development speed, budget, and long-term scalability.

Native app development means building separate apps for iOS and Android using their respective programming languages:

• Swift/Objective-C for iOS apps
• Kotlin/Java for Android apps

It gives you better performance, tighter integration with device features, and more control over the user experience.

Cross-platform development uses frameworks like React Native or Flutter (can also be used for progressive web apps). These languages allow you to build a single app that runs on both platforms.

This can save time and money, especially in early-stage startups, though it might come with some trade-offs in performance or deep platform-specific features.

Here’s a quick comparison to help you decide:

Your choice depends on your project goals, budget, timeline, and the experience you want to deliver to your users.

Testing

The mobile app performance testing stage is essential to ensure that your app works well on different mobile devices and operating systems.

It is important to thoroughly test the app’s usability, efficiency (safety, speed, resource use, and stability metrics according to standards), and user interface.

Creating apps does not end when the development and testing end. You also need to market your app to encourage your target audience to become your users.

How to Build a Successful App?

There are nearly 2 million apps in the Apple App Store and almost 3 million Android apps in Google Play. These apps span 34 categories, with Games taking the biggest share in both stores.

What can we make of these facts? A few key takeaways:

Competition is fierce. Your app idea may already be out there.

Lots of apps get made but aren’t catching on as hoped.

So, is it possible to launch a hit app in such a crowded market? And if so, how?

New App Marketing Strategy

The development budget is a part of the marketing cost.

As the process gains momentum, answers to how to effectively develop a popular app become vivid.

Pre-development marketing is crucial to creating a successful mobile application and knowing how to deliver the right product.

By the time you launch the application, it will have already gained significant traction.

The SpdLoad answer for how to develop an app considers app marketing before development.

In app marketing, we want you to follow two activities:

Launching the App

• In-App store

Understanding how to launch a mobile app startup is just as important as developing it. Not only will it facilitate installation, but it will also ensure a consistent level of user loyalty and performance.

A thorough app launch plan is crucial for startups hoping to gain a strategic advantage in the app store.

In addition to online and social media promotion, there are several other things to consider when launching an app.

The key here is App Store Optimization or ASO techniques. These include various aspects of how your app should be optimized to ensure its organic growth. For example, you can test different images, descriptions, use of videos and animations, use of emoji, etc.

As with other aspects, you will generate a hypothesis to test, determine the eligibility criterion, do A/B testing, and then choose the most effective one.

• Collect user feedback

User feedback is an essential component of the product life cycle and the foundation for its evolution. Learn about the issues to consider when adding a feedback module to a mobile app.

And the usual design, development, and overhead costs of various feedback mechanisms.

You can choose any form of feedback platform, including email, questionnaire, forums, polls, and app store reviews.

Launching the App In App Stores

Launching your app in different app stores is just as important as developing it. Not only will it facilitate installation, but it will also ensure a consistent level of user loyalty and performance.

Whether you’re releasing on iOS, Android, or both, your launch strategy can directly impact visibility, downloads, and keep your long-term users engaged.

Each app store has its own rules, audience, and optimization techniques. Let’s take a brief look:

To stand out in different app stores, use App Store Optimization (ASO). That includes:

• A clear and engaging app title and description
• High-quality screenshots and videos
• Relevant keywords and localized content
• A/B testing to see which assets convert better

Promoting a Startup

There are a variety of ways to advertise and promote your startup. Besides ASO, there are SEO, SMM, and other marketing channels that can guide you into better marketing. Also, there is always an option to outsource digital marketing to an agency or freelancers.

The way forward with marketing is similar to that of an MVP. You generate a hypothesis, test and measure it through channels, and adjust the assumptions accordingly.

Collecting feedback from users

User feedback is an essential component of the product life cycle and the foundation for its evolution. Learn about the issues to consider when adding a feedback module to a mobile app.

And the usual design, development, and overhead costs of various feedback mechanisms.

You can choose any form of feedback platform, including email, questionnaire, forums, polls, and Apple App Store and Google Play Store reviews.

After Launch

This is the part where you need to track your app’s progress, customer response, and feedback.

So, integrate analytical tools like Google Analytics, Flurry, Mixpanel, Fabric, Localytics, etc to connect your application’s performance.

Here, we look at four ways for application or product management, post-development.

1. User Engagement
2. Customer Satisfaction
3. Customer Acquisition
4. App Performance

For startups, using a CAC calculator is essential to monitor customer acquisition costs.

As an entrepreneur, you need to align the customer’s response with your post-deployment development.

And to track the response, set up some metrics.

To name a few:

• Churn Rate
• User Retention Rate
• Daily Active Users
• Cost per Acquisition (CPA)
• Lifetime value (LTV)
• ROI
• Monthly Recurring Revenue (MRR)
• Average Revenue Per User (ARPU)

A churn rate calculator is a useful tool for SaaS businesses aiming to maintain a stable customer base.

Based on these metrics and the customer response, you can scale the application.

Once these new features are added and deployed, maybe you can also rethink the revenue generation.

Based on the user feedback, you can also create a new and inclusive business model.

Added to the tracking and analytics, don’t forget to set up systems for customer support.

Cost identification is important to create the requisite revenue generation model.

You’ll need analytics that gathers qualitative input on your product’s prospects. Although metrics are commonly thought of as an excellent quantitative analysis method, acquiring qualitative insight does not exclude you from being data-driven.

Now you are set with every tip and information about how to start a mobile app startup.
