I had the pleasure working with Aman and the GMAV team on a custom mobile app solution for cross-border payment infrastructure that required extensive integrations. The entire team was great to work with from discovery to design and development. They take a very consultative approach to ensure all requirements are captured correctly, in addition to providing a value-conscious quote that works within our budget. Project was delivered on time and within scope. Would not hesitate to use them again.

Why Mobile-First
Why Mobile-First Is
No Longer Optional
Over 60% of all digital interactions happen on a mobile device. A great app isn't a feature, it's the primary relationship between your brand and your customer.
Retention vs. Mobile Web
Native apps retain users 3× better than mobile web. Push notifications, offline capability, and device integration create engagement loops that browsers can't replicate.
App Store = Discovery Channel
The App Store and Google Play are active acquisition channels with 650M weekly visitors. A well-rated app in the right category generates organic downloads at zero acquisition cost.
Hardware Access Unlocks Revenue
Camera, GPS, biometrics, NFC, and Bluetooth unlock use cases impossible on web (AR features, contactless payments, health tracking, and location-based services that drive measurable revenue.
Performance = Perception
60fps animations, instant responses, and smooth transitions aren't vanity) they determine whether users see your brand as premium or disposable. Performance is brand.
What We Build
Apps Built for
Every Platform
Six mobile development capabilities. One codebase standard.
01
Native iOS Apps
Swift and SwiftUI apps for iPhone and iPad. Built to Apple Human Interface Guidelines, optimised for App Store submission, and designed to hit top-chart performance benchmarks.
02
Native Android Apps
Kotlin and Jetpack Compose apps for Android. Material Design 3 compliant, Play Store ready, and tested across the fragmented Android device landscape.
03
Cross-Platform (React Native)
One codebase, two platforms. React Native for teams that need iOS and Android simultaneously without doubling engineering cost. Near-native performance where it counts.
04
Cross-Platform (Flutter)
Dart-based Flutter apps with pixel-perfect custom UI. Ideal for design-heavy apps where visual fidelity across platforms is non-negotiable.
05
MVP & Prototype Builds
Functional prototypes and MVPs in 4–8 weeks. Core user flows, real data, App Store-ready. Built to test market assumptions before full investment.
06
App Maintenance & Scaling
OS update compatibility, feature additions, performance optimisation, crash monitoring, and App Store review management as an ongoing engagement.
In Detail
Our Mobile Engineering
Standards
Every app we ship meets these benchmarks before it goes to review.
01: Compliance
App Store Compliance
We handle every App Store and Google Play guideline, privacy manifests, permission justifications, age ratings, screenshot requirements, and review process management. Clean first submissions.
02: Performance
Performance & Battery
60fps UI rendering, background task optimisation, memory management, and battery impact testing. Apps that run smoothly don't get uninstalled. We test on low-end devices, not just flagships.
03: Security
Security & Data Privacy
Encrypted storage, secure authentication (biometrics, OAuth, MFA), certificate pinning, and GDPR/CCPA compliance. Privacy-by-design from architecture through submission.
04: Resilience
Offline-First Architecture
Local data persistence, sync conflict resolution, and graceful degradation when connectivity is lost. Apps that work regardless of signal strength.
05: Analytics
Analytics & Crash Reporting
Firebase, Mixpanel, or Amplitude integration. Funnel tracking, user session recording, crash reporting, and A/B testing infrastructure wired in before launch.
06: DevOps
CI/CD & Release Pipeline
Fastlane, GitHub Actions, and TestFlight/Firebase App Distribution for automated builds and staged rollouts. Every release is reproducible, auditable, and fast.

Ask Our Mobile Expert →
Should we build native (Swift/Kotlin) or cross-platform (React Native/Flutter)?
Native when: you need maximum performance, platform-specific hardware features, or are building a flagship product with a large engineering budget. Cross-platform when: you need iOS and Android simultaneously, have a tighter budget, and your app doesn't require deep platform APIs. React Native is better for JS-heavy teams. Flutter is better for design-intensive apps with complex custom UI. We'll recommend based on your specific requirements.
How long does it take to build a mobile app?
An MVP with core user flows runs 8-12 weeks. A full-featured app is typically 16-24 weeks. Timelines depend on feature complexity, third-party integrations, and backend requirements. We provide a fixed-scope, fixed-timeline quote before any engagement begins.
Do you handle App Store submission?
Yes, fully. We manage App Store Connect and Google Play Console setup, metadata, screenshots, privacy policy requirements, age ratings, and the review process. We handle rejections and resubmissions. Clean submissions are the goal; we've done this hundreds of times.
What happens after launch?
iOS and Android release new OS versions annually, requiring compatibility updates. We offer post-launch retainer plans covering OS compatibility, bug fixes, minor feature additions, performance monitoring, and review management. Apps are never truly "done" - they need ongoing care.
Can you build the backend as well, or just the app?
Both. We can build the entire stack (app + API + database + admin panel) or integrate into your existing backend. For new projects, we typically recommend Firebase for speed, or a custom Node.js/PostgreSQL backend for complex business logic.
How do you handle app security?
Encrypted local storage (Keychain/EncryptedSharedPreferences), HTTPS with certificate pinning, biometric authentication, OAuth2/JWT token management, and GDPR/CCPA compliance by default. We include a security review before every submission.
Do you do React Native or Flutter exclusively, or native too?
All four. We have dedicated iOS (Swift/SwiftUI), Android (Kotlin/Compose), React Native, and Flutter teams. The recommendation always follows requirements - we don't push a single stack because it's convenient for us.
What's the minimum budget for a mobile app?
A well-built MVP (2-3 core flows, one platform) starts around the investment level of a custom website. A full-featured dual-platform app is significantly more. We're transparent about cost drivers: backend complexity, third-party integrations, and polish level during scoping. Contact us for a fixed-price estimate.
