Mobile App Development

Custom mobile app development in 2026 typically costs between $25,000 and $150,000 for most business use cases. A simple MVP app with core features sits in the $25,000–$50,000 range. A moderate app with user authentication, custom APIs, and third-party integrations runs $50,000–$100,000. Complex, multi-platform apps with advanced features exceed $100,000. The biggest cost drivers are the number of features, the platforms targeted (iOS, Android, or both), and the depth of backend integrations required.

It depends on your target audience. In the United States, iOS holds approximately 58–60% of the market, making it the priority for businesses targeting American consumers, especially in higher-income demographics. Android commands roughly 72% of the global market, making it the right choice for international reach or markets like India, Latin America, and Southeast Asia. For most businesses, the most cost-effective approach is cross-platform development using Flutter or React Native — one codebase that deploys to both iOS and Android simultaneously, reducing build time and cost by 30–50%.

A native app is built specifically for one platform — Swift for iOS, Kotlin or Java for Android. Native apps offer the best performance and deepest access to device hardware like cameras, GPS, and biometrics, but require two separate codebases, doubling development cost and maintenance effort. A cross-platform app uses a single codebase (typically Flutter or React Native) that runs on both iOS and Android. Cross-platform apps now deliver near-native performance for most business use cases and are 30–40% cheaper and faster to build. Deltaprotech recommends cross-platform for the majority of business applications unless you have specific hardware or performance requirements that demand native.

A simple MVP app typically takes 8 to 12 weeks. A moderate app with user accounts, APIs, and backend systems takes 12 to 20 weeks. Complex apps with multi-platform support, admin dashboards, and deep third-party integrations can take 5 to 8 months. Every Deltaprotech project begins with a discovery phase that produces a detailed feature scope and milestone timeline before any development starts — so you know exactly what to expect and when.

Both app stores require a developer account before submission. Apple charges $99 per year for an Apple Developer Program account. Google charges a one-time $25 fee for a Google Play Developer account. Beyond account setup, apps must pass a review process: Apple's review typically takes 1 to 3 days but can be longer for first submissions; Google Play reviews usually complete within 24 hours. Deltaprotech handles the full submission process as part of every app development engagement — including compliance with each store's technical requirements, privacy policy mandates, and app listing optimization.

Industry standard for annual app maintenance is 15 to 20% of the original development cost. A $60,000 app should budget approximately $9,000–$12,000 per year for ongoing maintenance. This covers iOS and Android OS compatibility updates (Apple and Google release major OS updates annually that can break existing apps), security patches, performance monitoring, bug fixes, and minor feature additions. Skipping maintenance is one of the most common and costly mistakes businesses make — apps that fall behind on OS updates get flagged or removed from app stores.

Yes — this is one of the most common and highest-value app development use cases. Deltaprotech regularly integrates mobile apps with CRMs like Salesforce and HubSpot, ERPs like SAP and NetSuite, payment gateways like Stripe, scheduling tools, custom databases, and internal business systems. Integration is handled through secure APIs. If your existing software has an API (most modern business tools do), your mobile app can connect to it. If it does not, we can build a custom middleware layer to bridge the systems.
