Mobile App Development

From prototype to App Store

We build native iOS apps with SwiftUI and cross-platform apps with Flutter. Both tracks go all the way through App Store submission and post-launch monitoring—not just code delivery.

Native or cross-platform?

The right answer depends on your users, timeline, and product requirements—not which framework is trending.

What we integrate

From offline-first data sync to biometric auth and in-app purchase, these are the platform capabilities we integrate in real products—not just demo setups.

Design to post-launch

Every mobile project follows the same four phases. You get visibility at each stage and a working build in hand—not just status updates.

01

Design

Figma flows, component specs, and prototype review with your team before a line of code is written.

02

Build

Iterative two-week sprints with demo builds delivered to TestFlight or Firebase App Distribution.

03

Submission

We handle App Store and Play Store submission—screenshots, metadata, review responses, and binary preparation.

04

Post-launch

Crashlytics and Sentry dashboards configured for your team. We monitor the first two weeks and fix launch-day issues on priority.

What makes the work different

We have shipped to the App Store, not just simulated it

FitPulse hit 40,000 downloads and a 4.8-star rating. RoutePilot runs daily operations for 1,200+ field staff across three countries. These are real production apps with subscription billing, offline sync, and live monitoring—not demos.

Architecture that survives the second year

Most mobile apps degrade because they were built without a clear state management strategy or module boundary plan. We use TCA or Riverpod from day one so the codebase stays coherent as features accumulate.

We write tests that catch production regressions

Unit tests for business logic, integration tests for data flows, and UI snapshot tests for critical screens. FitPulse shipped with 70% unit test coverage. Tests are not a checkbox—they protect your next release.

“FitPulse launched with 40,000 downloads in the first month. The test coverage meant we shipped the next three feature releases without a single regression.”

Common questions

The honest answer depends on your priorities. If the app is iOS-first, performance-critical, or deeply integrated with Apple APIs (HealthKit, ARKit, CoreML), native SwiftUI is the right choice—you get day-one access to every platform capability and the smoothest App Store review path. If you need iOS and Android at the same time, want to move faster, or are building a B2B tool where platform fidelity matters less than feature parity, Flutter delivers near-native performance from a single codebase. We help you make this call based on your users, timeline, and budget—not our preference.
We manage the full submission process: preparing binaries, writing App Store metadata and screenshots, handling age ratings and privacy declarations, and responding to reviewer questions. Apple review typically takes 24–72 hours for a new app and is faster for updates. We handle common rejection categories (guideline 4.3 similar apps, 2.1 information needed) and know what to avoid in the review binary.
Every mobile project ships with Crashlytics and Sentry configured and alerting to your team. We monitor crash rates, ANRs, and critical funnels for the first two weeks after launch, fixing P0 defects on priority at no additional charge. After that, ongoing support is on a retainer basis. We also assist with OS version updates—when Apple or Google introduce breaking changes, we help you adapt before they become store compliance issues.
Mobile projects are priced after a scoping call where we define screens, flows, third-party integrations, and platform targets. Simple focused apps (10–15 screens, one platform) typically fall in one range; full-featured multi-platform products with offline sync, IAP, and backend APIs are larger engagements. We give you a written estimate with milestones and a payment schedule before any work begins.
Yes—with a code audit first. Before committing to new feature work on an existing codebase, we review the architecture, test coverage, and third-party dependency state. If there are structural issues that would make new features unreliable or expensive to maintain, we surface those upfront so you can decide whether to refactor or proceed with known constraints.
You own everything. Code, assets, and the App Store listing are yours. We recommend keeping the Apple Developer account in your own name from day one—this prevents any transfer complications later. If you are using our account temporarily for development, we provide clear handoff steps to transfer the listing and certificates to your account before launch.
