An app that performs across Android's device fragmentation
Test against real screen sizes, manufacturers and OS versions so the app doesn't just work on your reference device—it works on the ones your users actually own.
Mobile App Development
Build a native Android app that performs on every device it reaches—engineered in Kotlin and Jetpack Compose, tested across real hardware and OS versions, and ready to pass Google Play review the first time you submit.
Reliable Android products built for every screen.

Quick answer
Android app development is the process of designing, building and releasing native apps for Android phones, tablets and other devices, typically using Kotlin and Jetpack Compose. Integr8e delivers Android app development end to end—strategy, UX, native engineering, device testing, Google Play submission and ongoing support.
Business outcomes
Integr8e approaches android app development as a business capability—not an isolated technical task. Priorities stay connected to the users, operations and results behind the work.
Test against real screen sizes, manufacturers and OS versions so the app doesn't just work on your reference device—it works on the ones your users actually own.
Build to Google's Material Design guidelines and Play Console policies from day one, so submission doesn't turn into a policy rejection loop.
Use Kotlin and Jetpack Compose directly instead of a cross-platform wrapper, so scrolling, animation, background tasks and permissions feel instant on real hardware.
Receive maintainable Kotlin source code, Google Play Console access and documentation for a product you control, not one locked to a single agency or contractor.
What we deliver
One connected team covers the decisions and delivery work needed to move from uncertainty to a dependable outcome.
Clarify the core user journey, target devices, Android version range and whether native—rather than cross-platform—is the right call before design starts.
Design navigation, interaction and accessibility that follow Google's Material Design guidelines so the app feels native to Android, not adapted from iOS.
Build the app in Kotlin and Jetpack Compose with Room and Retrofit, connected to secure backend services and APIs.
Connect biometric authentication, push notifications, background services, widgets and other native Android APIs your product needs.
Test across manufacturers, screen sizes, Android OS versions and network conditions, then validate against Google Play's policies before submission.
Manage Play Console, staged rollouts, versioning, crash monitoring and post-launch iteration using real usage data.
Is this the right fit?
Not every challenge needs the same team or solution. We start by testing the business case, current constraints and fastest credible route to value—then recommend a scope that fits the evidence.
Delivery architecture
The plan adapts to your context, while short feedback loops and visible milestones keep the engagement controlled.
Define users, core journeys, target devices, Android version range and the business case for a native build.
Prototype navigation, interaction and visual design against Google's Material Design guidelines before engineering starts.
Develop the app in Kotlin and Jetpack Compose in short iterations, with a working build on real devices at every milestone.
Test devices, screen sizes, Android versions, accessibility, performance and Google Play policies ahead of submission.
Submit to Google Play, monitor crashes and adoption, and prioritise updates using production evidence.
Technology context
We select platforms against security, scale, team fit, integration needs and the full cost of ownership.

Android app development is the process of designing, building and releasing native apps for Android phones, tablets and other devices, typically using Kotlin and Jetpack Compose. Integr8e delivers Android app development end to end—strategy, UX, native engineering, device testing, Google Play submission and ongoing support.
Integr8e designs and builds native Android apps, including UX design against Google's Material Design guidelines, Kotlin and Jetpack Compose engineering, backend and API integration, device and OS-version testing, and Google Play Console submission and support.
Native Kotlin and Jetpack Compose development gives the best performance across Android's wide range of devices, deeper access to Android APIs, and day-one compatibility with new OS releases—which matters for apps with background processing, widgets or hardware integration. Cross-platform tools can lower cost when you also need iOS from one codebase and performance needs are moderate. Integr8e reviews your requirements and audience before recommending either path.
Cost depends on scope—a focused MVP with a handful of core screens costs less than a full-featured app with backend integrations, offline support and complex business logic tested across many devices. Integr8e scopes the requirement first and provides a phased estimate with clear assumptions rather than a generic day rate.
A focused Android MVP typically takes eight to twelve weeks, while a fuller app with integrations, multiple user roles and broad device support takes longer. Integr8e defines milestones after discovery instead of giving an unreliable one-size-fits-all timeline.
Yes. Integr8e signs an NDA before discovery begins if you need one. Ownership and licensing are set out in the engagement agreement, and you receive the Kotlin source code, Google Play Console access and documentation—no hidden dependency on our team to operate or extend the app.
Yes. Integr8e audits the existing codebase, architecture, crash and performance data, and Google Play rating before planning an incremental rebuild or a phased Java to Kotlin migration that avoids a risky rewrite from scratch.
Integr8e validates the app against Google Play's Developer Program Policies before submission, prepares store listing assets, data safety declarations and metadata, and manages the Play Console release. If Google raises a policy rejection, we diagnose the specific policy and resubmit rather than guessing at a fix.
Yes. Android apps can connect to CRM, ERP, payment, identity and analytics systems through REST or GraphQL APIs, webhooks, or a dedicated integration layer, with secure authentication built around your existing infrastructure.
Integr8e can provide crash monitoring, Android OS compatibility updates, Google Play metadata and policy management, performance improvement and feature development after launch, matched to how actively the app is used.
