How to Develop an App for Both Android and iOS: A Guide for Business Owners and Investors

Designing mobile apps can be difficult, especially when you're designing for both of the two largest (and quite different) mobile operating systems.

Mobile applications are essential for businesses seeking to engage customers and drive growth. With billions of users on both Android and iOS platforms, developing an app that functions seamlessly on both is crucial for maximizing your reach and impact. 

However, navigating the intricacies of simultaneous app development can be challenging for business owners and investors. 

This comprehensive guide aims to demystify the process, offering insights into key considerations, best practices, and strategies to ensure your app delivers a high-quality user experience across both platforms. 

The Importance of App Development for Both Android and iOS

Developing apps that are compatible with both Android and iOS is crucial for maximizing reach and impact. These two platforms dominate the mobile landscape, with Android accounting for around 71.85% of the global market share and iOS holding a strong presence in key regions like North America and Europe. By targeting both platforms simultaneously, businesses can unlock access to a wider audience, increasing their app's potential for downloads, engagement, and revenue.

Creating a dual-platform app also ensures consistent brand experiences across devices, allowing businesses to engage users regardless of their choice of operating system. This uniformity can enhance customer satisfaction, build brand loyalty, and provide valuable insights into user behavior across different platforms. 

Additionally, launching on both Android and iOS simultaneously can give businesses a competitive edge, allowing them to capture diverse market segments and maintain relevance.

How to Make an App for Both iPhone and Android: Understanding the Platforms

In order to successfully design and develop an app that is compatible with both Android and iOS, you must understand the key differences between the platforms. Here are four key differences to keep in mind. 

1. User Demographic

The user demographics for iOS and Android differ significantly, influencing the way apps are designed for each platform. 

iOS users tend to be more affluent and located in developed markets, while Android is the dominant platform in emerging markets. 

This distinction means that iOS users often have higher disposable income, are more likely to spend money on in-app purchases, and prefer sleek, high-end user experiences. On the other hand, Android users represent a more diverse audience in terms of income levels and geographical location. This demographic spread can affect the app’s features, design elements, and even language support, depending on which audience you are prioritizing. 

For example, an app targeting affluent iOS users may emphasize premium features, while an app for Android could focus on accessibility and affordability.

2. Market Share

Android dominates the global market with a substantial share of over 70%, compared to iOS’s more modest percentage. This means that developing for Android offers the potential to reach a larger number of users globally, particularly in markets with high smartphone penetration but lower iOS adoption. 

However, iOS holds a strong lead in certain regions like the United States and the UK, where its market share can approach or even surpass Android’s. 

The broader market reach of Android makes it a must-target platform for businesses seeking global scale, but ignoring iOS can mean missing out on affluent, high-value users in key markets. 

The larger Android ecosystem also means more device variety, which adds complexity to app design and testing to ensure compatibility across various screen sizes and operating system versions.

3. Monetization Strategies

Monetization strategies differ widely between iOS and Android. iOS apps typically see higher revenue from in-app purchases and paid downloads, as iOS users are more inclined to spend money on apps. The Apple App Store is known for generating more revenue per user, despite its smaller market share. 

In contrast, Android users are more likely to engage with ad-supported apps. This means that if you’re planning to generate revenue primarily through ads, Android may offer a better return, whereas iOS is more suited to freemium models or paid apps. 

Understanding these monetization trends is key to selecting the right pricing structure for your app and planning for future revenue streams.

4. Customizing the User Experience (UI/UX)

While it’s possible to develop an app for both Android and iOS simultaneously, it’s essential to tailor the user experience for each platform. Android and iOS users have different expectations for how apps should look and function, influenced by the unique design guidelines and interaction patterns of each operating system. 

For instance, Android apps typically rely on a back button, while iOS uses swipe gestures and tab-based navigation. 

Fonts, icons, and layouts also differ between platforms, impacting how users perceive and engage with the app. 

Customizing the UI/UX for each platform ensures a seamless, intuitive experience for users on both Android and iOS, boosting satisfaction and retention rates.

Custom iOS and Android Application Design and Development

Custom iOS and Android app design and development are vital for businesses looking to create apps that align perfectly with their goals, brand identity, and user needs. 

Unlike generic or template-based apps, custom development allows businesses to design unique features, optimize functionality, and address specific pain points of their target audience. By creating an app tailored to the company's unique requirements, businesses can offer a more personalized experience, leading to better user engagement and retention. 

Additionally, custom apps provide scalability, flexibility, and integration with other business systems, making them a more sustainable long-term solution.

Tools like Flutter and React Native have become popular frameworks that support cross-platform development, enabling businesses to build apps that work seamlessly on both iOS and Android without having to develop two separate versions. 

Flutter, by Google, allows developers to use a single codebase to build native apps for both platforms, offering faster development and a consistent user experience across devices. 

Similarly, React Native, powered by Facebook, allows developers to write code once and deploy it on both platforms, reducing time and cost while maintaining near-native performance. These tools are ideal for businesses seeking to maximize efficiency while still providing a polished, high-quality app experience.

Simultaneous development for iOS and Android, made possible through cross-platform tools, offers additional advantages. By launching an app on both platforms at the same time, businesses can tap into a larger audience from the start, ensuring wider reach and faster user adoption. 

Using these tools in custom app development ensures that businesses do not have to compromise on user experience, as they can optimize their app to account for the differences between iOS and Android while still benefiting from the efficiencies of cross-platform development.

Key Differences in App Optimization for Android vs iOS

In terms of optimization, there are key differences that should be considered during the development and launch phases. 

App Submission Process

Google Play and Apple’s App Store have distinct submission processes that affect development timelines and overall app performance. Google Play allows for a quicker and less stringent submission process, where apps are usually reviewed and approved within hours. Developers can publish updates quickly and experiment with changes to improve the app’s performance or fix bugs. 

On the other hand, Apple’s App Store has a more rigorous and time-consuming review process, often taking several days. Apple reviews apps manually, evaluating their quality, security, and compliance with strict guidelines, which can delay the app launch but ensures higher standards of quality and security.

Optimization Tip: For Google Play, be prepared for rapid iterations by releasing frequent updates and gathering user feedback. For Apple’s App Store, ensure your app meets all guidelines before submission to avoid rejection and delays.

App Store Optimization (ASO)

Both platforms have their own approach to App Store Optimization (ASO), but they require different strategies. 

Google Play's ASO places a higher emphasis on keywords in the app description and title, making it crucial to include relevant search terms that align with user queries. 

In contrast, Apple’s App Store optimization focuses more on the app name, subtitle, and keywords entered in a designated field. Apple allows up to 100 characters for keywords, which are hidden from users but essential for ranking in searches.

Optimization Tip: On Google Play, include important keywords throughout the app title and description. For Apple’s App Store, focus on creating a compelling title and subtitle while carefully choosing high-traffic keywords in the keyword field.

In-App Performance Requirements

Apple places a strong emphasis on performance and user experience. Apps that are buggy, slow, or have a high rate of crashes may be rejected or removed from the App Store. Apple also evaluates adherence to privacy standards, security, and interface consistency. 

Google Play is less strict but still requires apps to meet basic performance and security requirements. Android apps must also account for a wider variety of devices, screen sizes, and hardware configurations, which can affect performance if not optimized properly.

Optimization Tip: For Apple, ensure your app is thoroughly tested for bugs and meets all interface and performance standards before submission. For Google Play, focus on optimizing the app for a broad range of devices by ensuring compatibility with different Android versions and screen resolutions.

Update Frequency and Flexibility

Google Play allows developers to push updates more frequently and with less oversight, which enables faster fixes and improvements. Apple, however, requires that each update go through the same review process as the initial submission, which can slow down the ability to make quick changes or fix issues.

Optimization Tip: Use Google Play’s flexibility to release more frequent updates and improve app performance based on user feedback. For Apple, carefully plan major updates to ensure they comply with all guidelines and deliver significant improvements.

The Impact of Developing Android and iOS App Simultaneously

When developing an app for both Android and iOS, businesses must consider how simultaneous development affects both the timeline and budget. 

Impact of Simultaneous Development on Timeline and Budget

Simultaneous development for both Android and iOS can significantly impact the timeline and budget of a project. 

While developing separate apps for each platform can be time-consuming and costly, using cross-platform frameworks like Flutter or React Native can reduce both the time and expense. These frameworks allow developers to write a single codebase that runs on both operating systems, which speeds up development, reduces resource allocation, and leads to faster launches. 

However, while simultaneous development shortens the initial timeline and lowers development costs, there are trade-offs in terms of post-launch maintenance and optimization.

Cross-Platform Frameworks and Post-Launch Maintenance

Although cross-platform frameworks accelerate app development, they may require more maintenance after launch. Since both platforms rely on a single codebase, even small platform-specific updates (e.g., changes in iOS or Android’s operating systems) can affect the entire app. This often leads to more complex debugging and testing to ensure that any updates work correctly on both platforms. 

Therefore, maintenance costs post-launch can be higher due to the need for ongoing updates to keep the app compatible with the latest versions of Android and iOS, as well as the broader range of device variations Android apps need to support.

Post-Launch Updates for Android vs iOS

Post-launch update processes differ significantly between Android and iOS. 

Google Play allows developers to roll out updates more frequently and quickly, often within hours, making it easier to push bug fixes or feature enhancements. 

Apple’s App Store, on the other hand, requires each update to go through an approval process, which can take days. This makes the update cycle for iOS apps slower and more regulated. 

The flexibility of Google Play allows for more iterative updates, whereas iOS apps often require more planning and thorough testing before submission to avoid delays.
