Native & Cross-Platform Development

Mobile apps that users love and businesses depend on

We build native iOS, Android, and cross-platform applications that deliver exceptional performance and user experience. From consumer apps to enterprise mobility solutions, mobile development that drives engagement and business results.

White Widget builds mobile applications that combine stunning user experience with robust functionality—we don't just port web interfaces to mobile, we design native experiences that leverage each platform's unique capabilities.

Our mobile development has helped consumer apps achieve top App Store rankings, enabled enterprises to deploy mobile-first workflows that increased productivity by 40%, and supported startups in launching viral applications that secured millions in funding. We build mobile experiences that users love and businesses depend on.

iOS App Development
Native iPhone and iPad applications built with Swift and platform-specific features.
iPhone users have the highest spending power and engagement rates of any mobile platform. But they also have the highest standards because they expect apps that feel like Apple built them. We create sleek iOS experiences that users actually want to keep on their home screen, not bury in folders.
How we get it done:
Secure Swift development with iOS SDK optimization
Apple Human Interface Guidelines implementation
Face ID, Apple Pay, and Siri integration
TestFlight beta testing and App Store submission
Android App Development
Native Android applications optimized for diverse devices and user experiences.
Android owns 71% of the global mobile market, but most companies only build for the premium 20%. We develop native Android apps in Kotlin that work beautifully across the entire ecosystem, from budget phones in emerging markets to flagship devices. When it makes strategic sense, we use Kotlin Multiplatform Mobile to share business logic while maintaining native performance on each platform.
How we get it done:
Secure native Android development with modern frameworks
Material Design implementation across all screen sizes
Multi-device testing from budget to flagship phones
Google Play optimization and staged rollouts
Progressive Web App Development
Web applications that work like native mobile apps with offline capabilities.
Why wait weeks for app store approval when you can launch immediately? Progressive Web Apps deliver native app experiences through the browser with push notifications, offline access, and home screen installation. No gatekeeping, fees, or update delays of traditional app stores.
How we get it done:
Service worker implementation for offline functionality
Home screen installation and push notifications
Native app performance through web technology
Cross-platform compatibility without app stores
Mobile Backend Development
Scalable server infrastructure and APIs designed for mobile applications.
Mobile apps have unique demands like offline sync, push notifications, and location tracking that standard web backends can't handle properly. Your users expect apps that work instantly, everywhere, even when their connection drops. We've built backends that handle millions of requests for ride-hailing platforms and real-time collaboration tools. Your mobile app will work smoothly whether users have perfect WiFi or spotty cell coverage.
How we get it done:
Build mobile-optimized APIs that sync data even when users go offline
Set up real-time notifications that reach users instantly across all their devices
Create auto-scaling infrastructure that handles traffic spikes without breaking
Implement security protocols and data encryption that protect user information
Optimize performance so your app responds quickly no matter where users are located
Real-Time Location & Fleet Apps
GPS tracking, mapping, ride hailing, and offline-first transportation applications.
Whether you're building the next ride hailing platform or optimizing delivery logistics, location apps require offline-first architecture and bulletproof reliability. We've built these systems and understand the high-performance development challenges.
How we get it done:
Offline-first GPS tracking and geofencing
Route optimization, even with multiple pick ups and drop-offs
Deep experience with Google Maps, HEREMaps, ArcGIS SDK, Pelias
Driver-passenger matching and fleet dashboards
Real-time messaging for coordination

“Over the pandemic, they helped save and optimize cost as well in smart ways... in the early days of lockdown, our revenue plummeted by something like 95%. White Widget brought down costs by more than 60%, and they did that fairly quickly.”

“
I was really impressed by their UX/UI expertise. White Widget is also incredibly professional. They are not afraid to take the time to clear up requirements and specifications before diving into the main development work
Wimbie S.
CTO, Baby Product E-Commerce Store

“
They always wanted to find the best solution. We didn't have a lot of experience in Android app development, and we wanted a partner to offer their input. White Widget was very good at providing advice on best practices on how to build an Android app.

“
They basically rebuilt our whole ride-hailing platform, which at the time was servicing upwards of 200,000 bookings a day — in the span of 10 months. Where possible, they’ve gone the extra mile.
Walter W.
Product Head, Ride-hailing Co.

“
The most important result is that our clients are very happy with the app. Most of our customers have to go through two or three days training, which is a lot of cost for them. With this app, they just pick it up and start using it. It's a very intuitive app, so they were very happy with it.
