What we ship
Swift, SwiftUI, UIKit. App Store optimization, push notifications, HealthKit, CoreData, offline storage. Built Unfold (featured at WWDC), MOTTIV (endurance training), and Free Stuff Finder (2M+ iOS installs).
Kotlin, Jetpack Compose, Material Design 3. Google Play distribution, background services, device fragmentation testing. Built Free Stuff Finder Android (2M+ combined installs) and WinitClinic Android.
One codebase for iOS and Android with shared components and design tokens. Built React Native apps for a US sports operations platform used by 100% of NFL teams.
RESTful APIs, push notification infrastructure, real-time messaging, authentication, and CDN-backed media delivery. Every mobile app needs a backend. We build both under one roof.
App Store and Google Play submissions, metadata optimization, screenshot design, review response strategy. We have shipped apps that reached #2 in their App Store category.
iOS version upgrades, Android API level targeting, dependency updates, crash monitoring, performance optimization. We maintain apps we built 5+ years ago.
Free Stuff Finder reached #2 in its App Store category. Over 2 million installs across iOS and Android. The app delivers curated deals, coupons, and freebies to bargain-hunters across the United States. WordPress serves as the headless CMS backend. Realm handles local data persistence. Push notifications drive daily engagement.
Unfold was featured by Apple at WWDC. A creative toolkit for social media content creation. Our iOS team built core features that Apple highlighted on stage.
MOTTIV serves 10,000+ athletes with personalized endurance training plans. Triathlon, marathon, running, cycling. Offline workout mode for training without internet. Built from scratch over 2 years.
These are not demo apps. They are production mobile applications downloaded by millions of users, featured by Apple, and maintained for years. That is what our mobile development team builds.

Swift and SwiftUI for new projects. UIKit when inheriting existing codebases. Our iOS developers build with HealthKit (MOTTIV fitness tracking), CoreData and Realm (offline storage for Free Stuff Finder), CoreLocation (delivery tracking for Ripe), and the full Apple ecosystem of frameworks.
We optimize for the App Store: app thinning, proper screenshot sets, metadata that converts, and review response management. Free Stuff Finder’s App Store presence was a deliberate product of optimization, not luck.
Kotlin and Jetpack Compose for new projects. Material Design 3 for consistent UI. Google Play distribution with proper feature flagging and staged rollouts. Device fragmentation testing across the Android ecosystem.
One codebase, two platforms. React Native makes sense when the app is primarily data-driven UI (lists, forms, dashboards, messaging) and you want to ship to both platforms with a single team. We built React Native mobile apps for a sports operations platform used by 100% of NFL teams.
When React Native does not fit (platform-specific camera work, heavy animations, health sensor integration), we build native.
Every mobile app needs a backend. Authentication, data storage, push notifications, real-time messaging, payment processing, and CDN-backed media delivery. We build mobile backends in Laravel, Django, and Node.js. The backend team sits next to the mobile team. One codebase review process. One deployment pipeline. One accountability.

Field notes
A production Flutter app costs $60K–$150K for V1. One codebase saves 20–35%, not half: backend, QA and native integrations set the real price.
Dennis Vorobyov 8 min read Quoted Android app development cost ranges span $20k to $300k+, but scope decisions and rework, not the hourly rate, decide what you actually pay.
