ServicesMobile and Application Development
Mobile apps that ship and stay installed.
We build native iOS, native Android, Flutter apps, progressive web apps (PWAs) and Chrome extensions that run in production. Our Apple App Store developer account has been active since 2012.
- Native iOS development:Swift, SwiftUI, UIKit, App Store submission and review management
- Native Android development:Kotlin, Jetpack Compose, Google Play submission and management
- Flutter cross-platform:Single codebase for iOS and Android, native performance, platform-appropriate UI
- Progressive Web Apps:Offline support, home screen installation, push notifications, no App Store required
- Chrome extensions:Browser-based tooling, workflow automation, team productivity
- App Store presence:Active Apple App Store developer account since 2012
- API and backend integration:REST, GraphQL, real-time data, authentication, push notification services
- App architecture:State management, offline-first design, performance profiling
- Post-launch support:OS updates, App Store compliance, bug fixes, feature iterations
Proven in Production
One of our earliest iOS apps, Battigayo, reached an estimated 100,000+ users and became one of Nepal's first viral consumer apps (2012 to 2018). Since then, we have shipped:
- Medibook, a medical directory app for Kathmandu (2013, retired)
- Two news apps still live on the App Store: The Rising Nepal and Gorkhapatra
- A Chrome extension for team timesheets
That track record matters because mobile is unforgiving. App Store review rejects apps that crash or mislead, and users uninstall apps that feel slow. Performance, reliability and polish are the cost of staying installed.
Native when it matters. Cross-platform when it makes sense.
We build native iOS and native Android when the product demands it. Platform-specific behavior, deep OS integration, hardware access, performance-critical interfaces.
We build with Flutter when the product is better served by a shared codebase. One Flutter codebase ships to iOS and Android at once, with a consistent UI across platforms. For most B2B tools, internal apps and early-stage consumer products we recommend Flutter: faster iteration and lower maintenance cost.
We also build Progressive Web Apps for teams that need mobile-grade experiences without App Store distribution. PWAs run in the browser, install on the home screen, and work offline.
What We Do Not Do
We do not take on mobile projects we cannot own. If your app requires hardware integrations, AR, or complex payment systems, we scope those precisely before we start. If the right answer is a PWA instead of a native app, we will tell you that, even if native is the larger engagement. The goal is a product that works.

Who This Is For
Startups
that need a mobile product shipped and kept running.
B2B product companies
that need a mobile companion or internal tool without standing up a dedicated mobile team. Flutter lets us ship and iterate without a separate iOS and Android team.
Enterprise teams
that need a Chrome extension, internal app, or PWA built to complement an existing web platform.
- Consumer iOS app published 2012. Reached an estimated 100,000+ users. One of Nepal's first viral apps.
- iOS medical directory app published on the Apple App Store.
- Chrome extension for team timesheet management shipped and used in production.
- Active Apple App Store developer account since 2012: apps.apple.com/in/developer/lastdoor-solutions
You need an app that ships and stays shipped.
We have the track record, the stack, and the App Store presence.
