Mobile App Development for iOS and Android | Applic
A full cycle of Android app development — from the first conversation about your goal to Google Play publishing and post-release support. Fixed cost, transparent timelines, an in-house team. No outsourcing — only people who bear direct responsibility for the result.
For whom
Which businesses benefit from Android app development?
Android covers about 72% of the global smartphone market. That means most of your customers already hold an Android device in their hands. Android app development isn't just a technical step — it's a direct channel to that audience.
If your customers use smartphones — and today that's practically everyone — an Android app secures this communication channel more reliably than any website. And your brand stays on the user's screen constantly, not only when they visit your site.
Quick checkout, Google Pay, push notifications about promotions
Secure transactions, biometrics, payment system integration
Trackers, doctor appointments, telemedicine
Booking, payments, CRM right in the client's smartphone
Corporate tools: tasks, reports, approvals
Interactive content, user progress, notifications
Order tracking, routes, delivery confirmation
Advantages
Key reasons to build an Android app
An app on a smartphone works differently from a website. It's always at hand, doesn't require logging in every time, and can send a notification at the right moment
An app doesn't sell itself.
A well-designed app sells.
Builders like Adalo can handle the task at the start — but when a business needs specific features, offline mode or integrations with corporate systems, native development becomes unavoidable. That's exactly where we begin.
Push notifications are read more often than email. A conversation with the customer — with no ad auctions or social media algorithms
A good app becomes part of your routine. It's harder to delete it than to forget to visit the website
Subscriptions, in-app purchases, loyalty programs—all of these are available on Google Play
Behavioral data not available through the website: conversion funnel, usage patterns, exit points
Android is the most popular operating system in the world, especially in Ukraine and Eastern Europe
Process
How to build an Android app: the stages
The process is built so the client always knows what's happening. The most common complaint about previous contractors isn't code quality — it's the lack of communication. We've closed that gap systematically
A well-designed app sells.
⌄We don’t start with the code—we start by understanding the problem. Who is your user, how do they behave, and what are they looking for in the app? We analyze competitors on Google Play: what works and where the gaps are. At this stage, we also define the monetization model—this influences the architecture. If you only have ideas so far, our specialists will use proven tools to help you refine them into a clear concept. At this stage, it becomes clear whether we need to build an Android app from scratch.
Preparation
⌄The spec is the contract between everyone involved. We lock down functionality, screens, navigation logic, integrations, the stack and performance requirements. No 'we meant something a bit different' halfway through development. The more precise the spec, the more predictable the timeline and cost of building the app.
Design
⌄UI/UX in Figma: wireframes, prototypes, final mockups. Everything is approved before development begins. The design follows Material Design — the app looks native on Android, not a layout ported from another platform. We work through edge cases: what the user sees with no internet, on first launch, on an error. Good design is a way to cut the number of code-stage revisions and speed up the whole project.
Development
⌄We write in Kotlin — a modern, safe language for Android recommended by Google. If a project involves Python for the backend or Java to integrate with legacy systems, we bring those in too. An in-house team, no outsourcing. Android mobile app development done our way means native code, not wrappers over web technologies. The architecture is designed for the project's future growth, not just the first release. We document the app's code and hand it over to the client.
Testing and Launch
⌄We test on real devices across different Android versions — not just emulators. Functional tests, regression, load, edge cases. We catch bugs before release. Google Play publishing — we help with metadata, screenshots, description and search keywords. Preparing the listing takes a few minutes of joint work with the client.
Support
⌄After launch we stay with the project. We monitor crash reports, ship updates for new Android versions, and add functionality per the roadmap. Google regularly updates its app requirements — without support a product degrades. Most of our clients work with us for several years in a row: after all, it's far easier to grow a product with a team that already knows its architecture.
Tech stack
What building an Android app involves
We use a native Android stack — with full access to Google's system APIs and no intermediate layers
Kotlin
The primary Android development language. Java — for legacy projects and integrations
Jetpack Compose
A modern declarative approach; XML + View — for supporting older versions
MVVM / Clean Architecture
Jetpack ViewModel, a scalable structure for project growth
Room / Retrofit
OkHttp, Firebase, GraphQL — data and networking
JUnit / Espresso
Mockito — unit, UI and integration tests
GitHub Actions
Firebase App Distribution — build and distribution automation
Figma / Material Design 3
Mockups, prototypes and a design system per Google's guidelines
For projects that need to cover iOS and Android at once, the optimal solution is cross-platform mobile apps built with Flutter or React Native, where Android mobile app development is part of a single process.

Real Problems - Real Solutions
East-West Air Cargo
22+ years of partnership
Toyota dealers received cars for service without recording the condition of the bodywork: after servicing, disputes arose and nothing could be proven. The solution — a mobile app for a 360-degree inspection right at the intake point: an employee walks around the car, photographs damage, and the client signs the report on a tablet. All data goes into the dealer's system in real time.
Result: Disputes over vehicle condition — zero. Intake processing time dropped by 35%. Data was never lost. The partnership has been going for over 22 years.

Frequently asked questions about Android mobile app development
How long does development take?
⌄It depends on complexity. A simple MVP — a few weeks, sometimes up to two months. An app with complex functionality, integrations and custom design — from 3 to 6+ months. We determine exact timelines after discussing the task and fix them in the contract. In practice, most delays happen not in development but in approvals — which is why we build in buffers and keep the client informed.
How much does it cost to build an Android app?
⌄For Android mobile app development, the price depends on several factors: functionality complexity, the number of integrations, how custom the design is, and performance requirements. A simple app and a complex B2B platform are fundamentally different tasks, so quoting a price without a spec isn't possible. Write to us — we'll estimate an approximate cost within 1–2 days.
What are Android apps written in?
⌄Native development — Kotlin as the primary language. For UI — Jetpack Compose or classic XML. Java — where compatibility with legacy code is needed. We use Python for backend services when the task requires it. If you need to cover iOS and Android at once — Flutter. Building an app for each platform starts with choosing the right stack — based on the project's needs, not by default.
Do you provide support and updates after the Android app is released?
⌄Yes. We stay with the project after launch: we monitor crash reports, ship updates for new Android versions, and add features per the roadmap. The option of long-term cooperation is our standard, not an add-on. Most clients work with us for years.
Can the app be integrated with existing systems and services?
⌄Yes — and it's a standard task. Ordering an Android app from us means we'll connect CRM, ERP, payment gateways (LiqPay, WayForPay, Stripe), the Nova Poshta API, the client's internal systems — anything with an open interface. We test the correctness and security of integrations separately. If a system has no API — we analyze alternative ways to connect.
Can the app be improved after release?
⌄Of course. Ordering an Android app isn't a one-off. An Android app is a living product: we add features, change logic, and scale the architecture as the business grows. If you already have an app that needs refinement or a rewrite — we take that on too.
