Mobile App Development
Native iOS, native Android, and cross-platform apps engineered to ship through the App Store and Google Play — and to keep working as the OS, devices, and your roadmap change underneath them.

What We Deliver
Apps That Ship And Survive The Next Os Update.
We build mobile apps the way they're meant to be built — native where native matters, cross-platform where the speed and reach of a single codebase makes sense. Swift and SwiftUI for iOS, Kotlin and Jetpack Compose for Android, React Native and Flutter when a unified codebase serves the product better than two parallel teams.
Mobile is unforgiving. Every iOS release breaks something, every Android device fragment has quirks, and the App Store review process punishes shortcuts. We engineer for that reality — proper architecture, automated testing across devices and OS versions, store-submission workflows that don't surprise you, and the kind of code structure that lets the next engineer add features instead of starting over.
- Native iOS apps (Swift, SwiftUI)
- Native Android apps (Kotlin, Jetpack Compose)
- Cross-platform apps (React Native, Flutter, Expo)
- Backend-for-mobile APIs and integrations
- App Store + Google Play submission and review management
- Push notifications, deep linking, offline support
The Stack
Modern Tools, Chosen For The Job.
Who We Build For
Built For Teams Actually Shipping Mobile.
Consumer Mobile Apps
Customer-facing iOS and Android apps with social, content, commerce, or community features. Engineered for App Store ratings and the kind of polish that survives competitive review.
Enterprise + Internal Apps
Field-team apps, internal tools, and B2B portals where your workforce relies on mobile to do their job. Offline-first when connectivity is unreliable, MDM-friendly when IT requires it.
App Modernization + Re-Platforming
Take an existing app off legacy native code, abandoned cross-platform frameworks, or unmaintained hybrid wrappers — and onto a stack that can be supported for the next five years.
How We Work
From Kickoff To First Build In 14 Days.
- 01
Day 1
Discovery + platform strategy
We learn your business, your audience, the platforms you need to support (iOS, Android, both), and whether native, cross-platform, or hybrid is the right architectural answer for your product.
- 02
Day 4
Architecture + design alignment
We map the app architecture, screen flows, navigation patterns, backend requirements, and third-party integrations against your goals. Design and engineering align so handoff is clean.
- 03
Day 7
Detailed proposal
A 12–20 page document with scope, timeline, pricing, platform decisions, store-submission strategy, and the testing matrix we'll hold the build to. Even if you don't move forward, the document is a high-value strategic asset.
- 04
Day 14
Kickoff + first build
First TestFlight + Firebase App Distribution build in your hands. Real code, on a real device, in your pocket by Day 14 — not a Figma walkthrough.

Pick The Engagement That Fits Your App Project.
Fixed Scope
Full-service team: mobile engineer(s) + designer + PM + QA. We manage end-to-end against a defined feature set, platform list, and budget.
Learn moreManaged Retainer
Dedicated mobile engineer at 20 or 40 hours/week, IDT-managed. Ideal for ongoing feature work, OS-update maintenance, and continuous iteration post-launch.
Learn moreFor v1 mobile app builds we typically recommend Fixed Scope — feature sets and platform targets define cleanly against a price. Once the app is in the stores, most clients shift to a Managed Retainer to handle iOS/Android updates, new features, and ongoing review-process work.
Common Questions
Frequently Asked About Mobile App Development.
Depends on platform count, feature complexity, and whether design is in scope. Rough ranges: simple single-platform app (basic features, REST API integration): $30K–60K. Mid-complexity dual-platform app (auth, payments, push, custom backend): $60K–150K. Complex consumer app or enterprise mobile platform: $150K+. We give a fixed-scope proposal within 7 days of discovery — no estimate range, an actual price.
Depends on three things. (1) Performance ceiling — heavy graphics, AR, or hardware integration favors native. (2) Team budget — one codebase across iOS + Android (React Native, Flutter) costs less to build and maintain than two parallel native teams. (3) Platform-specific UX — apps that need to feel deeply native on each platform favor native. For most product startups, React Native or Flutter is the right answer. For performance-critical or hardware-heavy apps, native. We help you decide during discovery, not by reflexively defaulting to either.
Yes. We manage the full submission process — App Store Connect setup, Google Play Console setup, app metadata, screenshots, review responses, and the resubmission cycles when Apple or Google flag something. We've shipped through Apple's review process enough times to know how to write rejection responses that work.
v1 cross-platform app with standard features: 12–20 weeks. Native iOS + native Android in parallel: 16–28 weeks. Complex consumer app with custom backend and integrations: 6+ months. Most timelines blow up because of feature creep mid-build — we hold the line on scope changes by pricing them as additions, not absorbing them.
Yes — and this is the part most agencies underprice or skip. iOS and Android push major OS updates yearly that break things. Apple and Google change submission policies constantly. Devices fragment. We offer Managed Retainers specifically for ongoing app work — OS-update fixes, new feature builds, performance tuning, store metadata updates.
Yes. Most apps need a backend — auth, user data, sync, push notifications, payments, analytics. We build backends-for-mobile in Node.js, Python, or whatever stack fits the product. Or we integrate with Firebase or Supabase for faster time-to-market. Or we connect to an existing backend you already have. Backend strategy is part of discovery, not an afterthought.
Yes. App modernization is a meaningful portion of our work — taking apps off abandoned frameworks (Ionic, Cordova, old Xamarin), legacy native codebases, or unsupported tech and rebuilding on a maintainable stack. The first step is always an audit: current code quality, dependency state, store-submission risks, and what migration actually buys you.
Push: OneSignal, Firebase Cloud Messaging, or native APNs/FCM depending on requirements. In-app purchases: StoreKit (iOS) + Google Play Billing (Android), with revenue split and subscription management handled. Analytics: Mixpanel, Amplitude, Firebase Analytics, or whatever your team already uses. These are standard integrations — scoped during discovery so they're in the build from day one.
