Mobile App Development in Washington, D.C.

LivingStoneSolution Technologies develops iOS, Android, and cross-platform mobile applications for startups, enterprises, and government clients. React Native is used for projects requiring a shared codebase across both platforms; Swift and Kotlin are used for native-only builds. Service coverage spans architecture design, API integration, App Store submission, and post-launch monitoring.

What We Build

Our mobile engineering practice covers four core delivery types: cross-platform apps that share a single codebase across iOS and Android, native apps built in Swift or Kotlin for maximum hardware performance, API-integrated apps that connect to cloud backends and third-party services, and App Store-ready products with full deployment and ASO support.

• Cross-platform (React Native) — single codebase for iOS and Android; feature parity with lower long-term maintenance cost
• Native iOS (Swift) — clean, maintainable Swift code for performance-intensive fintech, healthcare, and media applications
• Native Android (Kotlin) — memory-efficient Kotlin engineering for device-optimized Android delivery
• Enterprise and B2G apps — secure, compliance-aware builds for government and regulated-industry clients

How It Works

Each mobile application engagement follows a six-phase delivery process, from requirements definition through live monitoring. The phases are sequential with defined handoff checkpoints so clients review and approve before the project advances.

1. Discovery and scope — define user flows, platform targets, performance requirements, and compliance constraints
2. Architecture design — select framework (React Native vs. native), plan offline-first database, design API contracts
3. Development sprints — iterative builds with client review at each sprint boundary; native modules integrated as needed
4. Backend and API integration — connect push notifications (Firebase/APNs), OAuth authentication, WebSockets, and third-party APIs
5. QA and compliance review — device matrix testing, Apple App Store and Google Play Store submission and approval management
6. Launch and monitoring — CI/CD pipelines (Fastlane), over-the-air updates, and crashlytics monitoring post-launch

What’s Included

Standard mobile app engagements with LivingStoneSolution include design, development, backend integration, and store submission. The items below are included in a full-build contract; items marked “separate scope” are available as add-ons.

Pricing and Timelines

Mobile app development at LivingStoneSolution is priced per project scope, not on a fixed menu. Pricing depends on platform target, feature complexity, backend requirements, and compliance needs. Typical engagements range from focused MVP builds to multi-platform enterprise products.

• MVP / prototype — limited feature set, single platform, fast time-to-market; industry data indicates $25,000–$60,000 for a single-platform MVP (Netguru, 2026); custom quote required for LivingStone engagements
• Full-build (cross-platform) — React Native, full backend, store submission; industry data indicates most U.S. projects fall in the $50,000–$150,000 range for mid-complexity builds (Clutch, 2026); custom quote required
• Enterprise / B2G — multi-platform, compliance review, SLA; complex builds with compliance typically exceed $150,000 (Netguru, 2026); scoped on discovery call

Frequently Asked Questions

What is the difference between React Native and native iOS/Android development?

React Native uses a single JavaScript codebase that compiles to both iOS and Android. This reduces development time and cost when feature parity is required across both platforms. Native Swift (iOS) or Kotlin (Android) development delivers maximum hardware access and performance. Native is preferable for graphics-intensive, fintech, or healthcare applications with strict platform-specific guidelines.

Do you handle App Store and Google Play submission?

Yes. LivingStoneSolution manages the full compliance approval process for both the Apple App Store and Google Play Store, including policy review, metadata preparation, and resubmissions if required. App Store Optimization (ASO) consulting for keyword targeting is also included.

Can you integrate AI features into a mobile app?

Yes. AI integration — including custom LLM connections, Retrieval-Augmented Generation (RAG) pipelines, and AI customer support agents — is available as a separate scope item. This work is delivered by the same engineering team under LivingStoneSolution’s AI Integration practice.

Do you work with government or regulated-industry clients?

Yes. LivingStoneSolution operates a dedicated government and regulated-sector division (Livingstone Government) focused on 508-compliant and secure solutions. Mobile projects for federal, state, or regulated clients are scoped under that division’s compliance framework.

Where is the development team based?

The core team is based in Washington, D.C., with team members in Chicago, IL and New York, NY. LivingStoneSolution serves clients nationally and accepts global remote engagements.
