Mobile app development services cover the full process of building an app for smartphones and tablets — strategy, UI/UX design, development, QA, launch, and support. At FiftyFive Technologies, we deliver this end to end for iOS, Android, and cross-platform, from discovery through app-store launch and ongoing maintenance.
We build three main types: native apps (Swift/Objective-C for iOS, Kotlin/Java for Android), cross-platform apps (Flutter, React Native), and hybrid apps. We recommend the right type based on your performance needs, budget, and time to market.
Native apps are built separately for each platform in that platform's language, giving the best performance and device access. Cross-platform apps use one codebase (Flutter or React Native) for both iOS and Android, reducing cost and time to market with a near-native experience.
Timelines depend on scope, but many products reach a functional MVP within a few months. FiftyFive starts every engagement with a 2-week free proof of concept, so you see progress and validate direction before committing to the full build.
Cost depends on platforms, features, integrations, and complexity. FiftyFive bills monthly on actual man-hours — so you pay only for work delivered — and offers a 45-day credit period for remote teams. Book a free consultation for a scoped estimate.
Key factors include the number of platforms (iOS, Android, or both), feature complexity, third-party integrations, design depth, and ongoing support needs. Cross-platform builds typically cost less than maintaining separate native apps.
Look for proven delivery (FiftyFive has shipped 100+ apps), transparent pricing, time-zone-aligned collaboration, and a low-risk start. Our 2-week free POC lets you evaluate our team on real work before committing.
Yes. After launch, we provide ongoing support including bug fixes, performance enhancements, updates, and maintenance to keep your app stable, secure, and compliant over time.
