With over 70% of smart phones worldwide running Android, you're looking at billions of potential users. From budget phones in emerging markets to flagship devices in developed countries, Android's reach is unmatched. But here's the challenge—building an app that works flawlessly across thousands of different devices, screen sizes, and Android versions.
At BirajTech, we've mastered Android development. We build apps that perform smoothly whether they're running on a $100 phone or the latest Samsung Galaxy. Nearly a decade of experience means we've helped startups launch their first app and enterprises reach global audiences.
Not sure where to start? We help you make the right decisions from day one.
Our consultation covers business goals analysis, target audience research, competitor evaluation, and technical recommendations. Should you build native or cross-platform? Which features matter most? What's a realistic budget and timeline?
You'll get a clear roadmap outlining features, technical architecture, estimated costs, and launch strategy—your blueprint for success backed by years of experience.
Great apps aren't just functional—they're delightful to use. Our designers create Android interfaces that users love.
We follow Material Design principles while making your app feel unique. Starting with user research and wireframes, we build high-fidelity designs with interactive prototypes you can test on actual Android devices. Every screen, interaction, and animation is crafted to guide users naturally.
We also conduct usability testing with real users, revealing friction points and improvement opportunities we'd never catch otherwise.
What you get: User research, wireframes, high-fidelity designs, interactive prototypes, design system.
This is where your app comes to life. Our developers build custom Android applications using Kotlin and the latest Android frameworks.
Every app is built from scratch, tailored to your specific requirements. We work in 2-3 week sprints, delivering working builds regularly so you can see progress and provide feedback throughout.
We write clean, maintainable code following best practices and modern architecture patterns. Security is built in from the start—encrypted storage, secure APIs, and protection against common vulnerabilities. We also optimize for fast performance and battery efficiency.
Technologies: Kotlin, Jetpack Compose, MVVM architecture, Retrofit, Room, Hilt, Firebase.
Bugs kill apps. We find and fix them before your users do.
Our QA team conducts comprehensive testing across multiple Android devices, versions, and screen sizes. We test on real devices—not just emulators—because real-world behavior often differs.
What we test:
We use both manual testing and automated testing (JUnit, Espresso) to catch different types of issues.
Deliverables: Test plans, bug reports, performance metrics, compatibility results.
Online stores with product catalogs, shopping carts, secure checkout, order tracking, push notifications for deals, and payment gateway integration. Android's massive reach helps retailers connect with price-conscious shoppers globally.
Chat applications, social media platforms, dating apps, community forums, and messaging services leveraging real-time communication, media sharing, and social features.
Uber-style apps connecting service providers with customers—ride-hailing, food delivery, home services, beauty appointments, laundry, grocery delivery. Android dominates in markets where these services thrive.
Patient portals for booking appointments, teleconsultation with doctors, prescription management, health tracking, medication reminders, and integration with wearables for monitoring vital signs.
Interactive learning apps, virtual classrooms, video courses, quiz applications, language learning, exam preparation, and student management systems reaching students in underserved communities.
Mobile banking with account management, fund transfers, bill payments, digital wallets, investment tracking, loan applications, credit score monitoring, and UPI payment integration.

Apps helping farmers with weather forecasts, crop advice, market prices, government schemes, equipment rental, and expert consultations—particularly impactful in emerging markets.
We understand your vision, document requirements, define features, and establish success metrics. You'll get a comprehensive project scope, competitive analysis, timeline, and cost estimate.
We prioritize features, define technical architecture, choose the tech stack, and create a product roadmap. For complex projects, we recommend phased launches.
Designers create wireframes, then high-fidelity designs implementing Material Design. You get interactive prototypes to test on Android devices before development begins.
Development in 2-3 week sprints with regular demos. Each sprint includes planning, daily standups, coding, code reviews, and sprint demos. You receive builds to test throughout.
Comprehensive testing on real devices covering functionality, usability, performance, security, and compatibility. All bugs are logged, prioritized, and fixed.
Google Play Beta release to real users for 1-2 weeks. We monitor crashes, gather feedback, and make final refinements before public launch.
We prepare your store listing with optimized descriptions, screenshots, and video. Submission typically approved within hours.
Ongoing monitoring, bug fixes, Android version updates, performance optimization, and new features based on user feedback.
Simple apps take 2-4 months, medium complexity apps need 3-5 months, and complex apps require 6-12 months. We'll provide an accurate timeline after understanding your requirements.
Simple apps: $12,000-$35,000 | Medium complexity: $35,000-$90,000 | Complex apps: $90,000-$200,000+. Cost depends on features, design, and backend requirements. Contact us for a detailed estimate.
Build for the platform where your audience is. Android for global markets and emerging economies; iOS for premium audiences and higher revenue per user. Consider cross-platform (Flutter/React Native) to launch on both simultaneously.
We typically recommend Android 8.0 (Oreo) and above, covering 90%+ of active devices. We'll analyze your target audience and recommend the optimal minimum version.
Yes. We test on multiple devices from different manufacturers and screen sizes. We use responsive design principles for consistent experience across devices.
Rare, but if it happens, we address the issues and resubmit quickly—usually within 24 hours. We build compliant apps following Google Play's policies.
Yes. We offer App Store Optimization (ASO), launch strategy guidance, and can connect you with marketing partners for user acquisition.
