We design and ship production-ready mobile apps for iOS and Android — from MVP launches in 8–12 weeks to enterprise apps serving 100K+ users.
Swift and SwiftUI apps optimized for iPhone and iPad with Apple Human Interface Guidelines compliance. We handle App Store submission, TestFlight beta distribution, and push notification setup so your iOS app reaches users without launch delays.
Kotlin-based Android apps targeting API 26+ with Material Design 3 components. Our builds pass Google Play review requirements and include Firebase Analytics integration for measuring retention and crash-free sessions from day one.
Single Flutter codebase for iOS and Android reduces development time by 30–40% compared to dual native builds. Ideal for MVPs and startups that need both platforms live within 10–14 weeks without sacrificing native performance.
WebSocket, Firebase Realtime Database, and local SQLite caching for chat, live tracking, and field-worker apps. Users stay productive even with intermittent connectivity — a requirement for logistics and healthcare clients we serve.
We manage App Store and Google Play listings, screenshot assets, release notes, and OS compatibility updates. Ongoing maintenance retainers cover security patches, dependency upgrades, and crash monitoring via Sentry or Firebase Crashlytics.
We map user flows, define MVP feature set, and choose native vs. Flutter based on timeline, budget, and device-specific requirements like Bluetooth or ARKit.
Interactive Figma prototypes validated with target users before a single line of code is written — reducing rework during development by an average of 25%.
Two-week sprints with TestFlight and internal APK builds. Automated unit tests plus manual QA on 5+ physical devices before each release candidate.
App store submission, analytics setup, and a 30-day post-launch support window. We monitor crash rates and user feedback to prioritize v1.1 improvements.
