App Development Cost by Platform

One of the biggest factors influencing app development cost in 2026 is the platform you choose. Each platform comes with its own technical requirements, design standards, and development effort, which directly impacts the overall budget.

Android App Development

Android app development generally offers a lower entry cost due to its open ecosystem and broader device compatibility. It is an excellent choice for businesses aiming to reach a wide and diverse user base across different devices and regions.

However, supporting multiple screen sizes and hardware configurations can increase testing and optimisation efforts, which may slightly affect the final cost for feature-rich applications.

iOS App Development

iOS app development typically comes with a higher development cost due to Apple’s strict design guidelines, security standards, and performance expectations. iOS users are known for higher engagement and spending, making this platform ideal for premium and revenue-driven apps.

Businesses targeting quality-conscious users and polished user experiences often prioritise iOS development despite the higher initial investment.

Cross-Platform App Development

Cross-platform development using frameworks like Flutter or React Native allows businesses to build a single application that runs on both Android and iOS. This approach can reduce development costs by up to 40% and significantly shorten time to market.

Cross-platform apps are ideal for startups and growing businesses looking for cost efficiency without compromising core functionality, scalability, or performance.

Native App Development

Native app development involves building separate applications for Android and iOS using platform-specific technologies. This approach delivers the best performance, responsiveness, and user experience, especially for complex or high-traffic applications.

While native development comes with a higher overall cost, it is often the preferred choice for enterprise-grade applications that require advanced features, deep system integration, and long-term scalability.

At Fulminous Software, we help businesses choose the most cost-effective platform strategy based on their goals, target audience, and long-term growth plans—ensuring maximum return on investment.

UI/UX Design Cost in 2026

In 2026, UI/UX design is no longer just about visual appeal—it plays a critical role in driving conversions, improving user retention, and shaping how customers perceive your brand. A well-designed interface can significantly reduce user friction and increase engagement.

Modern applications require a user-first design approach backed by research, usability testing, and performance optimisation. This makes UI/UX design a strategic investment rather than a cosmetic expense.

• Wireframing & Prototyping: Creating clear user flows and interactive prototypes to validate ideas before development begins.
• Custom UI Elements & Animations: Smooth transitions, micro-interactions, and branded animations that enhance user experience.
• User Research & Testing: Real-user testing to identify usability gaps, improve navigation, and maximise engagement.
• Accessibility & Compliance: Designing inclusive interfaces that meet accessibility standards such as WCAG, ensuring usability for all users.

On average, UI/UX design accounts for 10–25% of the total app development cost, depending on the complexity of the interface and the level of customisation required.

At Fulminous Software, our UI/UX experts combine design thinking with business strategy to create intuitive, conversion-focused interfaces that deliver measurable results.

Technology Stack and Cost Impact

• Frontend: Flutter, React Native, Swift, Kotlin
• Backend: Node.js, .NET, Python, Java
• Database: PostgreSQL, MongoDB, Firebase
• Cloud: AWS, Azure, Google Cloud
• AI: OpenAI APIs, custom ML models

Region	Hourly Rate
UK / USA	$70 – $150
Western Europe	$50 – $100
Eastern Europe	$35 – $70
India / Asia	$20 – $45

Security & Compliance Costs in 2026

In 2026, security is a non-negotiable component of application development. With rising cyber threats, stricter regulations, and increased user awareness around data privacy, businesses must invest in robust security frameworks from day one.

Security and compliance costs vary depending on the type of application, industry, and geographic region, especially for apps handling sensitive user, financial, or healthcare data.

• Data Encryption: End-to-end encryption for data at rest and in transit to prevent unauthorised access and data breaches.
• Secure Authentication: Implementation of multi-factor authentication (MFA), biometric login, role-based access control, and secure session management.
• Penetration Testing & Vulnerability Assessment: Regular security testing to identify and fix potential weaknesses before attackers can exploit them.
• Compliance Audits: Ensuring adherence to regulatory standards such as GDPR, HIPAA, PCI-DSS, and ISO security guidelines based on business requirements.

On average, security and compliance measures can add 10–25% to the total app development cost, but this investment significantly reduces the risk of financial loss, legal penalties, and reputational damage.

At Fulminous Software, we embed security into every stage of the development lifecycle, ensuring your application is compliant, resilient, and trusted by users.

Post-Development & Hidden Costs

Many businesses focus only on initial development costs, but post-launch expenses play a crucial role in the long-term success and scalability of an application. Proper planning for these costs prevents budget overruns and ensures consistent app performance.

Maintenance & Support

Ongoing maintenance includes bug fixes, performance optimisation, OS updates, security patches, and technical support. In 2026, businesses should budget approximately 15–25% of the initial development cost annually for reliable maintenance and support.

Hosting & Infrastructure

Hosting costs depend on user traffic, storage needs, data transfer, and cloud services used. Cloud-based infrastructure typically costs between $1,000 – $15,000+ per year, with higher costs for enterprise-grade or high-traffic applications.

Feature Enhancements & Scalability

As your business grows, new features, third-party integrations, and performance upgrades become necessary. These enhancements represent an ongoing investment that evolves alongside market demands and user expectations.

Fulminous Software offers flexible post-launch support and scalability plans to help businesses grow their applications without compromising performance or security.
