Types of apps

Understanding the several types of app development and categories of mobile applications available to startups is crucial to determining which aligns best with their business objectives and target audience. The primary types include:

Native apps: Developed specifically for a single platform (iOS or Android) using platform-specific programming languages and tools. They offer optimal performance and seamless user experience but require separate development efforts for each platform.

Cross-platform apps: Built using frameworks like Flutter or React Native, these apps can run on multiple platforms with a single codebase, reducing development time and cost. However, they might not fully leverage all native features.

Progressive web apps (PWAs): These web apps behave like native apps and are accessible through web browsers without requiring installation. They are cost-effective and easy to maintain but may have limited access to device hardware and features.

Hybrid apps: Combining elements of both native and web apps, enables these apps to operate across platforms. They offer a balance between cost and performance but may not match the responsiveness of native apps.

Steps in app development

Any startup looking to jump into the world of mobile app development for their customers’ needs to remember a series of structured steps to ensure the final product meets user expectations and business goals:

• Idea validation: Begin by brainstorming potential app ideas and evaluating them against market needs. Conduct surveys or focus groups to gather feedback and refine your concept.
• Market research: Analyze the target market to understand user demographics, preferences, and existing solutions. This research helps identify gaps and opportunities for your app.
• Define features and functionality: List the core features your app will offer. Prioritize functionalities that address user pain points and differentiate your app from competitors.
• Choose the development approach: Decide between native, cross-platform, or hybrid development based on your target audience, budget, and desired user experience.
• Design the user interface (UI) and user experience (UX): Create wireframes and prototypes to visualize the app’s layout and flow. Focus on intuitive navigation and engaging design elements.
• Develop the app: Begin rendering your app’s features by ensuring your team follows the best practices possible while maintaining clear communication throughout the entire front-end and back-end development process.
• Testing: Conduct thorough testing to identify and fix bugs, ensure compatibility across devices, and validate that the app meets performance standards.
• Launch: Prepare for deployment by setting up app store accounts, creating marketing materials, and planning a launch strategy. Submit the app to relevant app stores and monitor its performance.
• Post-launch support and updates: Gather user feedback to make necessary improvements, fix issues, and release updates to enhance functionality and user satisfaction.

Factors affecting mobile app development for startups

When considering mobile app development as a startup, several factors can shape the various outcomes of this process for any company. One of the biggest considerations is budget.

Most startups are working with limited resources, which means every decision – like which features to include, which platform to build on, and how much to invest in marketing – must be carefully thought out. If your budget is tight, you’ll need to prioritize the most essential features and opt for a more cost-effective development approach, like cross-platform instead of native.

Another key factor is time. If you’re trying to get your app to market quickly a minimum viable product (MVP) is best. An MVP focuses on core features, with the app being built out later through future updates. Speed can be a big advantage, but it also requires making smart choices about what your app really needs at launch.

Platform selection is also a major decision. Whether you go with iOS, Android, or both can influence the mobile app development timeline and costs for startups significantly. It really comes down to your target audience. If they mostly use iPhones, starting with iOS makes sense. But if your users are spread across different devices, it might be worth developing for both platforms from the beginning.

Then there’s the user experience. A well-designed app that’s intuitive, easy to use, and visually appealing can go a long way in keeping users engaged. Even the best ideas can fall flat if the app feels clunky or confusing. That’s why investing in solid UX and UI design from the start is so important – it can be the difference between an app that people love and one they abandon after the first use.

Additionally, depending on what your app does, especially if it collects user data or operates in a regulated industry, you’ll need to ensure it complies with all the necessary laws and regulations. Things like data protection, user consent, and privacy policies can’t be overlooked, because skipping over the fine print could lead to serious trouble later.

All these elements – budget, timing, platform, design, and compliance – come together to shape the path of app development for startups. The better you understand how they work together, the more prepared you’ll be to make decisions that set your app up for success.

Examples of successful mobile apps

Now you know the different types of apps, how to build them and what can impact the development process, it’s time to show you examples of some mobile apps that have been incredibly successful in their own markets. Examples of such apps include:

1. Pizza Hut

As Pizza Hut faced increasing competition from food delivery apps and changing customer expectations, they needed a way to modernize their ordering process. The goal was clear: offer a seamless, mobile-first experience that could handle peak demand, integrate with real-time inventory and promotions, and maintain a consistent brand feel across devices. Their challenge was not only technical but strategic – how to stay competitive in a space being rapidly dominated by third-party platforms like Uber Eats and DoorDash.

Pizza Hut chose to build a cross-platform app using React Native, which allowed their development team to write one codebase for both iOS and Android. This decision dramatically reduced development time and ensured uniform design and performance across devices. The app integrates with Microsoft Azure cloud services, using APIs to manage orders, track locations, and push promotions based on local inventory or regional campaigns.

This approach allowed Pizza Hut to keep their technology nimble and scalable. Real-time order tracking and customized offers helped boost repeat business, while cloud scalability ensured stability even during high-demand periods like the Super Bowl or Black Friday. Their success lies in how they used modern cross-platform infrastructure to offer convenience and speed – the two things every hungry customer wants.

2. H&M

H&M’s challenge was to bring their massive retail experience into the mobile era without losing the curated, fashionable edge that made their brand iconic. With a vast global presence, they needed an app that was not only beautifully designed but also responsive to inventory, pricing, and customer preferences across multiple markets. More than just a shopping app, it had to become a personal stylist, a cashier, and a loyalty portal all in one.

To meet these needs, H&M opted for native apps – separately developed for iOS and Android – ensuring high performance and responsiveness, especially in UI-rich areas like product galleries and augmented reality try-ons. Their backend runs on SAP Commerce Cloud, enabling deep integration with customer accounts, real-time inventory data, promotions, and CRM systems.

The result is a fast, polished app that feels personal and localized. Customers can check if an item is in stock at their nearest store, receive targeted promotions, and even scan barcodes in-store to explore styling tips and alternatives. This seamless integration between the digital and physical shopping experience has made H&M’s app a critical part of their omni-channel retail strategy.

3. Starbucks

Starbucks revolutionized the coffee experience not just through drinks, but with their mobile app. Their biggest challenge was enhancing customer convenience and loyalty in an environment where people value speed and personalization. Long lines, inconsistent reward tracking, and missed orders were pain points that the app needed to solve – while still feeling like a premium part of the Starbucks brand.

They chose a native approach to development, optimizing for both speed and user experience. The infrastructure behind the scenes relies heavily on AWS and a microservices architecture, allowing features like order-ahead, digital tipping, and real-time customization to scale independently. The app is also deeply tied to their Starbucks Rewards system, which offers personalized deals and tracks visits seamlessly.

This infrastructure not only improved performance but also created one of the most successful loyalty programs in retail. The mobile app now accounts for a sizable portion of in-store purchases, and the integration with Apple Pay and Google Pay makes checkout effortless. Starbucks’ app isn’t just a convenience, it’s a strategic tool that drives repeat visits, increases order value, and deepens brand engagement.

4. IKEA

IKEA faced a unique challenge: their iconic catalog experience wasn’t translating well into the mobile age. Customers wanted to visualize how furniture would look in their homes, check availability, and place orders on the go – but the old web experience couldn’t support those needs in a fast, mobile-native way. IKEA needed to turn mobile into a discovery and conversion platform.

Initially, IKEA used a hybrid app approach, which allowed rapid rollout across multiple countries. However, performance and design limitations soon led them to invest more in native and React Native solutions for key experiences. Their app now uses Google Cloud Platform and integrates ARCore to offer augmented reality features – letting customers see furniture in their own space before buying.

This shift enabled IKEA to meet modern shoppers where they are: on their phones, making fast, informed decisions. The AR feature dramatically reduced product returns, and real-time inventory updates made store visits more efficient. By investing in high-performing mobile infrastructure, IKEA turned its app into a central part of the customer journey, from inspiration to purchase.

5. JP Morgan Chase

As consumer expectations for convenience evolved, traditional banks like JPMorgan Chase faced a major challenge: how to digitize their vast range of services in a way that felt modern, secure, and effortless. With millions of users and a reputation built on trust, Chase not only needed to provide a feature-rich mobile experience but also uphold the highest standards of security and performance. The challenge was to take complex financial systems and make them mobile-native without sacrificing reliability or compliance.

To meet this need, Chase opted for a native app architecture, developing separate applications for iOS and Android. This gave them the control needed to fully leverage device capabilities, optimize performance, and offer advanced biometric authentication like Face ID and fingerprint login. Under the hood, the Chase app is powered by a custom microservices architecture deployed through private and hybrid cloud infrastructure – with AWS and internal data centers working together to ensure redundancy, compliance, and speed.

Chase invested heavily in the app’s infrastructure to support real-time services such as transaction tracking, fraud alerts, credit score monitoring, and mobile check deposits. They also introduced a smart chatbot assistant and integrated AI-based budgeting tools. Because banking is deeply personal, the app focuses on user experience design that is clean, reassuring, and easy to navigate, giving users fast access to services without overwhelming them with complexity.

This strategy has worked incredibly well. Chase Mobile is now one of the top-rated banking apps in the U.S., with tens of millions of active users. It’s credited with reducing call center volume, increasing customer satisfaction, and improving cross-sell opportunities. By combining secure, scalable infrastructure with a native-first mobile strategy, Chase has managed to turn what was once a chore – banking – into something people prefer to do on their phones.

These are just five examples of successful mobile apps in vastly different industries, but there are many more. That just leaves us with one more question to answer…
