Mobile App Development Services for iOS and Android

    Most mobile apps die between the pitch deck and the App Store review. The wrong framework gets chosen, platform constraints get ignored, and the app that ships is slow, drains batteries, and gets rejected twice. Stixor builds mobile apps in React Native and Flutter that ship, perform, and stay in the store. Both platforms, one codebase, native quality.

    What Do Mobile App Development Services Include?

    Mobile app development services cover the design, build, and release of applications for iOS and Android devices. This includes cross platform development using React Native or Flutter for teams shipping both platforms from one codebase, app store submission and approval management, and the backend APIs, authentication, and infrastructure the app depends on. Stixor delivers this end to end, from product strategy through app store launch and post release support.

    The Stixor Approach to Mobile App Development

    We build mobile apps that ship on time, perform on real devices, and survive App Store and Play Store review. Every engagement is structured around what determines mobile success: real hardware performance, store compliance, and a codebase your team can extend.

    WHY US

    Right Stack, No Bias

    Native is right when performance and platform depth matter most. Cross platform is right when time to market and team economics take priority. We recommend based on your product, your team, and your timeline, not our preferred framework.

    Built for Store Review

    We build with App Store and Play Store guidelines from sprint one: permission handling, subscription flows, privacy declarations, and platform design guidance. Fewer rejections means faster releases and less rework for your team.

    Real Device Performance

    We test on real hardware including older devices, slow networks, and low battery scenarios. Simulators lie about performance. Every release ships with testing across the OS versions your user base actually runs.

    Backend That Grows with the App

    An app is only as reliable as the backend it talks to. We build APIs, authentication, push notifications, analytics, crash reporting, and feature flags alongside the app from day one, not when problems arrive in production.

    CAPABILITIES

    Mobile App Development Capabilities We Deliver

    Six core engagement patterns cover the full spectrum of mobile app work. Each can be engaged standalone or combined into a broader mobile program built around your product and platform requirements.

    React Native App Development

    Mobile apps in React Native with TypeScript for teams already invested in the JavaScript ecosystem. React Native shares code across iOS and Android while still allowing native module access when the framework needs to reach platform specific APIs. Ideal for products backed by web teams, startups shipping both platforms fast, and apps where business logic is shared across mobile and web.

    • React Native development with TypeScript and Expo
    • Native module integration for platform specific features
    • Code sharing between mobile and web where architecture supports it
    • Performance optimization for smooth animations and fast load times

    Flutter App Development

    Mobile apps in Flutter with Dart for products that need pixel perfect consistency across iOS and Android. Flutter renders its own UI layer, which means identical visual behavior on both platforms without platform specific shimming. Ideal for products with custom UI, animation heavy interfaces, or teams starting fresh without an existing JavaScript codebase

    • Flutter development in Dart with Material and Cupertino widgets
    • Custom UI components and animation heavy interfaces
    • Platform channel integration for native device features
    • Single codebase delivering consistent UX across iOS and Android

    Backend, APIs, and Mobile Infrastructure

    Every mobile app needs a backend. We build APIs, authentication systems, and infrastructure services designed for mobile client patterns. Push notifications, deep linking, analytics, crash reporting, feature flags, and remote configuration wired in from day one so you can operate the app without releasing every time something needs to change.

    • Backend APIs in Node.js, Python, or Go designed for mobile clients
    • Authentication: OAuth, SSO, biometric, and social login
    • Push notifications, deep linking, and universal links
    • Analytics, crash reporting, feature flags, and remote configuration

    App Store Optimization and Launch Strategy

    Getting into the store is only the start. We handle submission assets, metadata optimization, screenshot design, category positioning, and the review process for both App Store and Play Store. Post launch, we monitor ratings, reviews, and conversion metrics to improve store listing performance over time.

    • App Store and Play Store submission and review management
    • Metadata optimization: title, subtitle, description, and keywords
    • Screenshot and preview video preparation for store listings
    • Post launch monitoring of ratings, reviews, and conversion rates

    In App Monetization and Subscription Integration

    We implement in app purchases and subscriptions on iOS and Android including receipt validation, subscription lifecycle handling, and RevenueCat integration for subscription management. Trial flows, promotional pricing, paywall A/B testing, and analytics showing where users convert and churn are part of standard monetization work.

    • In app purchases and subscription implementation on both platforms
    • RevenueCat integration for subscription management
    • Paywall design, A/B testing, and conversion analytics
    • Trial flows, promotional pricing, and churn tracking

    OS Updates and Ongoing Mobile Maintenance

    Mobile OS updates break things. New versions deprecate APIs, change UI behavior, and introduce privacy requirements that break existing apps. We monitor platform announcements from Apple and Google, evaluate impact on your app, and ship updates before deprecations become mandatory. Available as an ongoing retainer so your app stays current without pulling your team off feature work.

    • iOS and Android OS update impact assessment
    • React Native and Flutter framework version upgrades
    • Dependency updates and deprecated API migration
    • Ongoing feature development and maintenance on retainer
