Android apps that reach billions of users worldwide.
Native Kotlin apps built with Material Design — optimized for the diverse Android device ecosystem, Google Play policies, and emerging markets.
Kotlin-first apps using Jetpack Compose, Coroutines, and modern architecture (MVVM, Clean Architecture) that stay maintainable at scale. We optimize for the real Android world — thousands of device profiles and OS versions back to Android 8.
Pixel-perfect interfaces with dynamic color, motion, and adaptive layouts for phones, tablets, and foldables. Material-compliant apps consistently score better in Play Store ratings and reduce user confusion.
Data safety forms, target API level compliance, app signing, and staged rollouts managed end to end. We keep your app ahead of Google's annual target-SDK deadlines so it never gets delisted.
Migration from Java to Kotlin and from legacy XML layouts to Jetpack Compose, done module by module without freezing releases. Modernized apps see build times and crash rates drop significantly within the first quarter.
Wear OS companions, Android TV experiences, and Android Auto integrations that extend your app across Google's ecosystem. We handle the distinct UX constraints and certification requirements of each form factor.
Baseline Profiles, startup tracing, memory leak hunting with LeakCanary, and WorkManager scheduling that respects Doze mode. We target cold starts under 1.5 seconds and crash-free rates above 99.5%.
We pick the right technology for your goals — not the trendiest framework.
“Devlex built an AI-powered quoting engine that cut our sales team's turnaround from two days to twenty minutes. They handled the LLM integration, the guardrails, and the training — and it actually works in production, not just in demos.”
“Our e-commerce replatform to a headless architecture was delivered GDPR-ready and PCI DSS compliant on the first audit pass. Page load times dropped 60% and conversion rose 18% in the first quarter after launch.”
“Devlex migrated our entire fintech backend to AWS with zero downtime over a single weekend. Infrastructure costs came down 35% and their DevOps team now runs our 24/7 monitoring under a clean SLA.”

Consumer apps, on-demand platforms, fintech apps with UPI and payment integrations, logistics and field-force tools, and enterprise apps for managed device fleets. All native work is Kotlin with Jetpack Compose; we also support legacy Java codebases.
An Android MVP takes around 3 months; a complete app with backend and Play Store launch takes 4-6 months. Supporting tablets, foldables, or Wear OS adds 2-5 weeks depending on scope.
Typical projects range $12,000 to $50,000 based on feature depth, device coverage, and backend needs. The Google Play developer account is a one-time $25 fee, and Play takes 15% commission on the first $1M of annual in-app revenue.
Yes — full Kotlin source, Gradle configuration, signing keys, and documentation transfer to you, with the app published on your own Play Console account. We sign IP-transfer agreements as standard.
We test on a matrix of 15+ real devices spanning Samsung, Xiaomi, Google, and OnePlus plus Firebase Test Lab's cloud devices. Maintenance plans from $800/month keep your app compliant with Google's yearly target API requirements and new Android releases.
We complete the data safety section, content rating, and store listing, then publish via staged rollout (5% to 100%) to catch issues early. Play review typically takes 1-3 days for new apps; updates usually clear within hours.
