Mobile Apps Built to Earn Their Home-Screen Spot.

Most mobile app engagements at AddWeb land between $20,000 and $200,000 depending on platform coverage, integrations, and AI features. Discovery-only sprints start at $5,000. We provide a written, line-itemed estimate within 48 hours of a scoping call — no boilerplate ranges, no padded contingencies.

An MVP typically ships in 10 to 16 weeks. A full enterprise mobile platform with backend, AI features, and App Store / Play Store approval runs 18 to 32 weeks. We commit to a fixed timeline after a 2-week paid discovery and publish a weekly burndown so you always know what is at risk.

Native (Swift for iOS, Kotlin for Android) is the right choice for graphics-intensive apps, deep hardware integration, AR/VR, or apps that demand absolute platform-native UX. Cross-platform (React Native or Flutter) is the right choice for most business apps — it cuts cost by 30 to 50 percent, reduces time-to-market by ~40 percent, and shares a single codebase. We help you pick during discovery — never push one approach to suit our bench.

Depends on the audience. iOS-first is right for premium, US- or UK-skewed consumer apps and fintech (higher ARPU, faster approval). Android-first is right for global, emerging-market, or high-volume utility apps (greater reach, more device diversity). For most B2B apps, we recommend cross-platform simultaneous launch to avoid splitting your audience in half.

Both are first-class at AddWeb. React Native fits teams already in the JS/React ecosystem and apps with heavy custom UI animations. Flutter fits teams that want pixel-perfect UI consistency across platforms and faster prototyping with Dart. We choose during discovery based on your team, your existing codebase, and your product roadmap — not a default preference.

Yes — and this is one of our differentiators. We ship on-device ML (Core ML, ML Kit, TensorFlow Lite), in-app LLM features, voice agents, computer vision, OCR, and recommendation engines as part of the core product. Our dedicated AI engineering unit has been running for four years, so AI in your app is a built-in capability, not a contractor handoff.

Native: Swift, SwiftUI, Kotlin, Jetpack Compose. Cross-platform: React Native, Flutter. Backend: Node.js, Python, Laravel, Firebase, GraphQL APIs. AI on device: Core ML, ML Kit, TensorFlow Lite. Cloud: AWS Amplify, Firebase, Azure Mobile Apps. CI/CD: Fastlane, GitHub Actions, Bitrise. Analytics: Firebase Analytics, Mixpanel, Amplitude.

Yes. We handle the full submission process — App Store Connect setup, Play Console setup, App Privacy declarations, screenshots, metadata, build signing, TestFlight and internal testing tracks, phased rollouts, and review-rejection handling. Most clients see first-submission approval. When rejections happen, we have direct experience navigating Apple and Google’s review teams.

Yes. ASO is part of launch and post-launch. We handle keyword research for App Store and Play Store, title and subtitle optimization, screenshot A/B testing via Apple’s product page tools, ratings and reviews strategy, and ongoing keyword ranking tracking. Most clients see 30 to 60 percent organic install uplift in the first 90 days.

AddWeb is ISO 9001 (quality) and ISO 27001 (information security) certified. We deliver HIPAA-aligned (US healthcare), PCI DSS-aligned (payments and fintech), GDPR-compliant (EU), and SOC 2-aligned mobile apps. We follow Apple’s App Privacy and Google’s Data Safety frameworks. Every build passes OWASP MASVS mobile security verification before submission.

Post-launch we offer SLA-backed maintenance plans (24×7, 12×5, or 8×5 coverage), proactive crash and performance monitoring, OS upgrade testing (every iOS and Android major release), security patches, and quarterly architecture reviews. Most clients retain a smaller version of their build team for ongoing feature releases — this is why our 98 percent retention rate is what it is.

Yes — it is one of our most common engagements. We start with a 1 to 2-week code and architecture audit, deliver a written rescue plan with risk ratings, and quote a recovery roadmap. We have inherited mobile projects from in-house teams, prior agencies, and freelance contractors across native iOS, native Android, React Native, Flutter, and older hybrid frameworks (Ionic, Cordova, Xamarin).

Both. Fixed-price suits well-scoped MVPs and one-off releases. A dedicated team (typically 3 to 10 engineers plus a PM, designer, and architect) suits ongoing product development where the roadmap evolves. Many clients start fixed-price for the MVP and shift to a dedicated team post-launch for the long-term product roadmap.

Four ways. First, see our G2 recognition among Best Mobile App Development Companies. Second, request our Capabilities Deck and recent app case studies. Third, read our 74+ verified Clutch reviews. Fourth, book a 30-minute strategy call where a Solution Architect — not a salesperson — gives you a free technical review of your app idea or existing build. Most decisions get made off that call.
