Mobile Application Development
Overview
Mobile App Development in Baku, Azerbaijan – iOS & Android Apps | ONE Studio
Mobile is where customers spend their time. The right mobile app can replace your website, your call centre, your store. ONE Studio builds mobile applications for clients across Azerbaijan and internationally — native iOS and Android, cross-platform with React Native and Flutter, and Progressive Web Apps. We deliver from concept and UI/UX through development, App Store / Google Play submission, post-launch support and ongoing iteration.
Mobile development services we offer
- iOS app development — native Swift/SwiftUI apps for iPhone and iPad. Full Apple Human Interface Guidelines compliance.
- Android app development — native Kotlin/Jetpack Compose apps. Material Design compliance and full Android API support.
- Cross-platform development — React Native and Flutter for one codebase shipping to both platforms. Faster, more cost-effective for many use cases.
- Progressive Web Apps (PWAs) — installable web apps without App Store distribution. Right for some products.
- Backend development — APIs, authentication, real-time features, push notifications, analytics — built to support the mobile app.
- App store submission — Apple App Store and Google Play preparation, screenshots, descriptions, ASO (App Store Optimization), launch coordination.
- App maintenance and updates — bug fixes, OS compatibility (new iOS / Android releases), feature additions, performance tuning.
- App migration — old hybrid app to native, monolithic app to modular, legacy stack to modern.
- App audit and recovery — diagnosing performance issues, abandoned development, technical debt cleanup.
Our mobile development process
- Discovery and strategy. Business goals, target users, key features, technical constraints, monetisation, timeline.
- UI/UX design. Wireframes, user flows, prototypes, high-fidelity designs in Figma. Mobile-first thinking — different from web.
- Architecture. Tech stack selection, backend architecture, data models, API design, scalability planning.
- Development. Sprints (typically 2-week), continuous integration, code reviews, test-driven where appropriate.
- QA testing. Real devices, multiple OS versions, edge cases, performance, accessibility.
- App store submission. Apple and Google review processes — we handle compliance, screenshots, metadata, ASO basics.
- Post-launch. Monitoring crashes, user feedback, performance. Hotfixes and feature releases on regular cadence.

iOS or Android first? Native or cross-platform?
iOS or Android first: Depends on your audience. In Azerbaijan, Android leads in volume but iOS users have higher purchasing power. Premium services often launch iOS-first; mass-market apps Android-first. Most enterprise clients launch both simultaneously.
Native or cross-platform:
- Native (Swift / Kotlin) — best performance, full platform features, longer development time, separate iOS and Android codebases.
- React Native — single JavaScript codebase, 80% performance of native, faster development, occasional native code for specific features.
- Flutter — single Dart codebase, near-native performance, growing ecosystem, beautiful UI capabilities.
- PWA — web app that feels native, no app store, no install. Right for some products but limited platform features.
For most business apps, React Native or Flutter is the pragmatic choice. For graphics-heavy games, real-time apps and apps requiring deep platform integration: native is worth the extra investment.
Common questions about mobile development
How long does an app take to build? Simple: 3–4 months. Mid-complexity: 5–8 months. Complex: 9–18 months.
Will I own the source code? Yes — full ownership including iOS / Android codebases, backend code, design files.
What about after launch? Apps need regular updates — OS compatibility (every iOS/Android release), bug fixes, new features. We offer maintenance retainers.
How do you handle App Store rejections? Most rejections are predictable — we follow Apple/Google guidelines from day one. When they happen, we fix and resubmit within days.
Do you do app store optimization (ASO)? Yes — keyword research, screenshots, descriptions, A/B testing of store assets to improve organic install rates.
Can you help with marketing the app? Yes — through our digital marketing services, including paid app installs, ASO and influencer marketing.
What about backwards compatibility? Standard support: iOS 15+ and Android 9+. Older OS versions on request, with cost trade-offs disclosed upfront.

Process
Advantages of developing a mobile app for business:
Direct communication with customers: Information about campaigns and discounts is instantly delivered to customers via mobile apps.
Competitiveness: In today’s competitive environment, having a mobile app is a key requirement for companies to keep up with competitors and ensure successful operations.
Customer interaction: The feedback section available in most mobile apps helps users send their inquiries, feedback, suggestions, and comments directly.
Customer base: Offering promotions and giving special attention to users who download the company’s app helps turn them into loyal customers.
Stages of mobile app development
- Analytics
We analyze the competitive market environment, select the best solutions, and aim to create high-quality products. We sign an NDA. We review your technical brief (if there is none, we’ll help prepare it). By the second stage, we already have a description of the main functions of the app.
- Design and prototyping
Based on analytics, we implement your business goals with user-friendly interfaces. We develop a screen map, graphic elements, and a detailed (static or interactive) prototype, considering various usage scenarios. We strive for the best user experience — intuitive, easy to use, and functional interfaces.
- Development and programming
We code the prepared designs. We write clean and stable code and integrate it with the client’s technologies. The coding process is iterative — we develop and test one part before moving to the next. Designers actively monitor the process and verify the consistency of the screens.
- Testing phase
We test the app on different devices and guarantee on-time delivery of a quality product. From the start of the project, our QA engineers are involved; we prepare test documentation and conduct acceptance testing before release — verifying all business scenarios in practice.
- Publication on App Store and Google Play
We publish your app on App Store, Google Play, or any other platform of your choice. Important note: to pass store moderation, you can use our assistance or manage the process independently.
- Support and development
After release, the app’s journey does not end. We continuously improve the product based on user feedback, adding new features and enhancing the user experience. We work to maintain top rankings and attract thousands of downloads.
How much does mobile app development cost?
“How much does a mobile app cost?” — this is perhaps our most frequently asked question. The project’s cost depends on the volume and scope of work. We usually agree on a fixed price, and clients are always happy with both the conditions and the outcome.
The price is determined after preparing the technical brief and gathering all requirements. Payment can be broken into stages, each tied to a new version release. At each stage, you receive a ready, functional part of the product.
After successful publication, a final acceptance document is signed and the project moves into the support phase. Here, we discuss and evaluate new features and development plans. Using analytics, we track the effectiveness of key scenarios, measure conversion rates at each stage, and propose solutions to improve business performance.
Timeframe for developing iOS and Android apps
To calculate cost, it’s important first to clearly define all app functionalities. Initial estimates are based on the requirements list, with a more precise calculation after prototyping and brief preparation. The prototype models all screens, navigation, and user actions of the future app. On average, development takes 4 to 10 weeks.
