Android App Development Company
Apps Users Actually Keep
We build Android apps on Kotlin and Jetpack Compose with a full architecture sprint before Sprint 1 starts. Real-device testing on every build. Play Store launch, ASO, and monitoring included. Your app earns a 4-star-plus rating because the architecture was planned to survive actual devices, not just the emulator.
Every sprint. Every device tier.
We test on physical hardware because the emulator does not catch every Galaxy A14 crash.
The rating falls before
anyone calls it a failure.
Play Store rating over 12 months (typical unarchitected app)
from 14,200 reviews
"Crashes every time I try to upload a photo. Samsung Galaxy S23. Unusable." - 3 months ago
"Battery drains 40% in 20 minutes. This is not normal. Pixel 7 user. Update killed the app." - 5 months ago
Five architecture shortcuts that turn early downloads into 2-star reviews:
Memory not managed: your app crashes on budget phones
Activities and Fragments hold references past their lifespan. On a Samsung Galaxy A14 — the most common Android device sold globally — the app freezes or crashes. The Pixel 8 team says it works. The Play Store says otherwise.
API calls on the main thread: the app freezes mid-task
Blocking the UI thread with network requests triggers Android's NetworkOnMainThreadException. The screen locks. The user force-quits. Uninstall rates spike in the first week.
Permission prompts at the wrong moment: users deny and never come back
A camera permission dialog before the user sees the camera feature gets denied by default. The feature breaks. No fallback exists. The user rates 2 stars and moves on.
Background tasks drain the battery: your app gets blamed in reviews
A wakelock held too long, no WorkManager, no Doze awareness. Battery drain complaints appear in Play Store reviews within 2 weeks of launch. Some manufacturers auto-kill your app.
Broken notifications and deep links: your marketing budget goes nowhere
Push notification taps open the wrong screen. Email campaign deep links land on a blank page. Every marketing dollar spent acquiring users hits a broken front door.

From architecture sprint
to Play Store live in a straight line.
Architecture sprint. The full blueprint before Sprint 1 code is written.
You see the complete technical plan before any production code runs. We deliver a Figma navigation graph, Kotlin data model document, OpenAPI contract, dependency injection map, and local/remote data strategy — all in two weeks. Sprint 2 starts with shared understanding, not assumptions.
UX Design. Every screen validated against a real Android user before engineering starts.
Figma screens built to Material Design 3 guidelines, with a dynamic color system, typography scale, motion tokens, and component library. An interactive prototype goes to stakeholders before engineering begins. Usability testing on target devices happens before Sprint 3. No screen enters development that a real user has not reviewed on actual Android hardware.
Core build. 100% Kotlin, Jetpack throughout, every layer testable.
100% Kotlin. No Java interop unless a third-party SDK forces it. Jetpack Compose handles UI. Hilt manages dependency injection. Coroutines and Flow handle async operations. Retrofit handles network calls. Room handles local persistence. DataStore replaces SharedPreferences. Every layer is testable. Every dependency is injectable. That means your team can maintain and extend the codebase without dependency on Redefine after handoff.
class HomeViewModel @Inject constructor(
private val repository: UserRepository
) : ViewModel() {
val uiState: StateFlow<HomeUiState> =
repository.getUsers()
.stateIn(viewModelScope,
SharingStarted.WhileSubscribed(),
HomeUiState.Loading)
}
Device testing. Real hardware. Every sprint.
Firebase Test Lab runs the full test suite across a device matrix: entry-level (Galaxy A14), mid-range (Pixel 6a), and flagship (Galaxy S24). Robo tests crawl every screen path. Automated UI tests verify critical flows. Performance profiling on the lowest-spec target device in the matrix. Crash-free rate target agreed before launch. If it fails the threshold, we do not ship.
Play Store launch. ASO, staged rollout, and monitoring from day one.
Store listing copy, screenshots, feature graphic, and short description written to ASO guidelines. Privacy policy and data safety form completed. Staged rollout configured starting at 10% of users. Firebase Crashlytics and Performance Monitoring live from day one. You see the rating trend, ANR count, and crash-free rate in the first 24 hours. Nothing launches without a monitoring plan.
Looking at cross-platform or backend options? These fit into the same stack:
A real estate app. Custom QR scanning.
Launched on iOS and Android simultaneously. 4.8 stars.
Case Study · Mobile app product team reviewing launched app on devices
Homes and Lands
Real Estate Platform
A mobile app to showcase property listings and real estate agents, featuring custom QR scanning, secure user data, and simultaneous iOS and Android delivery.
Homes and Lands needed a mobile app that let buyers browse property listings and contact agents, all without friction. The challenge: custom QR scanning for property sign-ups, strict App Store and Play Store compliance, and a simultaneous dual-platform launch. One failed submission would delay the entire go-to-market.
Custom hardware scanning + dual-platform delivery + strict store guidelines — all required at launch.
combined Play Store and App Store rating at launch. Custom scanning shipped on time. Both stores approved on first submission.
First submission approved on both App Store and Play Store
Custom QR scanning feature shipped at launch with no extra delay
4.8 combined store rating from first users — no patch cycle required
Six things we treat as standard on every Android engagement.
Real-device testing. Every sprint.
Firebase Test Lab runs every sprint. Entry-level to flagship. If it does not pass on a Galaxy A14, it does not ship to anyone.
Performance budgets set before Sprint 1.
Cold start target, crash-free rate, and ANR threshold agreed before coding begins. CI fails the build if any metric falls below target.
Security designed in from day one.
EncryptedSharedPreferences, certificate pinning, biometric auth, and ProGuard obfuscation are architecture decisions made in Sprint 1. Not sprint 18 additions squeezed in before launch.
Offline-first by default.
Room local cache, sync queue, and conflict resolution designed upfront. Your app works in a tunnel, not just a fast WiFi network.
Play Store listing and ASO written by us.
Store listing, screenshots, feature graphic, and data safety section completed by us. You do not spend launch week writing Google Play descriptions.
Architecture docs your team owns at handoff.
Navigation graph, module diagram, data flow docs, and contribution guide delivered at handoff. Any Android developer you hire can onboard in days.
What product owners and CTOs ask us before they sign.
Platform choice, timeline, and testing approach matter more than most agencies admit. Straight answers here.
Scoped before work starts. Line-by-line pricing. No commitment to receive a proposal.
An app discovery sprint delivers a full architecture document, screen flow, and sprint plan. You see every deliverable and cost before signing.
Tell us what you are building. We will be direct about fit.
Select the cards that match your project. We name the engagements we are not right for — as clearly as the ones we are.
Not sure where you land? Describe your app and we will give you a straight answer on platform, scope, and timeline.
Building a consumer app that needs to retain users beyond day 30
Push notifications, personalization, in-app payments, and Play Store rating management matter.
Enterprise app with SSO, MDM, and security requirements
Your IT team manages device policy. Your security team has compliance requirements. We build Android apps that satisfy both without slowing down the product team.
B2B field app that works offline and syncs when connected
Warehouses, field sites, and rural routes all have spotty connectivity. Your field staff cannot afford an app that needs a signal to function.
Existing Android app with poor ratings or performance issues
A code audit identifies memory leaks, ANR causes, battery drain, and architecture debt before you start rebuilding.
Not the right fit if:
Your total Android budget is under $12,000
A 5-screen app with an architecture sprint and real-device testing takes real engineering hours. We give you a scoped cost before any work starts, but the floor is real.
You need a no-code app builder or template-based solution
We build custom applications. If a template fits your needs, we will tell you and point you toward the right tool.
Tell us what the app needs to do. We scope the build and send line-by-line pricing.
