iOS & Android
Mobile App Development for Products That Need to Scale
We build iOS and Android apps for products where performance, reliability, and user experience actually matter. No template apps, no offshore juniors reviewing each other's work. Senior engineers who have shipped apps used by hundreds of thousands of real users.
Native vs Cross-Platform — When Each Makes Sense
Native (Swift + Kotlin)
Full access to platform APIs, best-in-class performance, and the reliability characteristics the App Store and Play Store actually reward.
- →Real-time GPS tracking with background location
- →Complex animations and gesture-driven UI
- →Hardware integration (camera, sensors, BLE)
- →Offline-first with local data sync
- →Apps competing directly with platform-native tools
Cross-Platform (React Native)
Single codebase for iOS and Android, faster iteration, and lower cost — without meaningful performance trade-offs for most product categories.
- →Standard UI with shared business logic
- →Rapid MVP validation
- →Budget or timeline constrained
- →Web team wants to contribute to mobile
- →B2B apps where UI complexity is manageable
We recommend based on your actual product requirements. If cross-platform will cause problems in your specific case, we will tell you — even if native costs more.
Performance-First Development
Most mobile performance problems are architectural — caused by decisions made in the first two weeks of a project that cannot be undone cheaply. We design for performance from the start so you are not refactoring for it six months before launch.
Cold Start Time
App launch sequences designed to minimize perceived wait time. Skeleton screens, progressive data loading, and deferred initialization for non-critical components.
Smooth Scrolling
List rendering optimized for 60fps — cell reuse, image caching, diffing algorithms, and off-main-thread layout when the platform supports it.
Battery & Memory
Background process management, location update frequency tuned by trip state, image memory pressure handling, and leak detection as part of our standard review process.
Network Resilience
Optimistic updates, request queuing for offline, retry logic with exponential backoff, and graceful degradation when connectivity is poor.
Mobile Case Studies
Transportation · 4 Mobile Apps
Ride-hailing platform — passenger and driver apps for iOS and Android
Four native mobile apps (passenger iOS, passenger Android, driver iOS, driver Android) with real-time GPS tracking, push notifications, and in-app payments. Platform expanded to multiple cities in 12 months with 3x driver fleet growth.

Frequently Asked Questions
Native or cross-platform — which should I choose?
Native (Swift for iOS, Kotlin for Android) when you need maximum performance, hardware access, or background process reliability — GPS tracking, real-time audio, complex animations. Cross-platform (React Native, Flutter) when you need a single codebase, your UI is mostly standard components, and budget or timeline is constrained. We make the recommendation based on your specific product, not our tool preferences.
How long does it take to build a mobile app?
A focused MVP with core flows — typically 8–14 weeks. A full production app with onboarding, authentication, payments, real-time features, and offline support takes 4–8 months. The range is real and driven by scope, not padding.
Can you take over an existing mobile app?
Yes. We do code audits, performance reviews, and incremental modernization — or full rewrites if the existing codebase is unsalvageable. We will tell you which after reading the code, not after signing the contract.
Do you handle App Store and Google Play submission?
Yes. App Store and Google Play submission, rejection handling, review guideline compliance, and certificate management are included. We have shipped dozens of apps through both stores.
How do you handle offline support?
Offline-first architecture requires deliberate decisions about sync logic, conflict resolution, and local storage. We design this upfront — it cannot be bolted on later without significant rework.
Can you integrate with our existing backend?
Yes. We integrate with REST APIs, GraphQL, WebSockets, and custom backend protocols. If your backend does not have a mobile-friendly API layer, we can build one as part of the engagement.
Do you do product design or just engineering?
Both. We can run full product and UX design alongside engineering, or slot into an existing design system and just build. We do not treat design as a separate workstream — designers and engineers work together from week one.
Have a mobile app to build?
Tell us what you are building, who it is for, and what success looks like. We will tell you the right approach and whether we are the team to build it.
