Build Your Mobile App Without the Handoffs
Most mobile projects fail at the seams — the handoffs between discovery agencies, design studios, dev shops, and QA contractors. Scope drifts. Bugs slip through. Timelines stretch.
We have built mobile apps differently since 2008. Business analysis, UX/UI, native iOS, native Android, cross-platform, dedicated QA engineers, and post-launch support all sit under one roof at Uran Company. Over 500 projects later, the model still holds.
What We Build
Native iOS Apps
Swift-first development for iPhone and iPad. We work with the current iOS SDK, Apple's Human Interface Guidelines, and App Store review requirements. Legacy Objective-C codebases are also supported when we inherit existing projects.
Native Android Apps
Kotlin-first development against the latest Android SDK. We handle Material Design 3 components, Jetpack libraries, and Google Play policy compliance. Where business logic justifies it, we will integrate Java modules in mixed codebases.
Cross-Platform Apps
Flutter and React Native, chosen per project after a short technical discovery. Single codebase, two stores, faster time-to-market — when the use case fits. We will not push you to cross-platform if your app needs deep native performance or hardware integration that justifies two codebases.
Backend and APIs
Mobile apps without solid backends do not ship. We build REST and GraphQL APIs, integrate third-party services (payments, auth, analytics, chat), and design for the scaling profile your app actually needs — not the theoretical millions of users a slide deck might promise.
The Full-Cycle Process
Most vendors quote you for 'development' and treat everything else as out-of-scope. Our default engagement covers the full lifecycle. Each phase has a defined deliverable and a named owner on our side.
Discovery
UX/UI Design
Output: clickable Figma prototype, design system, asset library.
Designers work in pairs with the development lead to keep designs implementable. Every screen ships with state coverage: empty states, error states, loading, offline.
Development
Output: working app in agile sprints, two-week cycles.
iOS and Android teams work in parallel where applicable. Code reviews are mandatory. CI/CD pipelines run on every commit. You see builds at every sprint demo, not just at the end.
Quality
Assurance
Output: tested build, regression suite, bug-tracking artifacts.
QA engineers are assigned from day one of development, not bolted on at the end. Test cases are written alongside features. Manual testing covers real devices across screen sizes and OS versions. Automated testing (XCUITest, Espresso, or Appium for cross-platform) catches regressions.
Launch
Output: app live in App Store and Google Play.
We handle store submissions, review correspondence, and rejection appeals. Crash reporting (Firebase Crashlytics, Sentry) is configured before launch, not after the first complaint.
Post-Launch Support
Output: retainer for fixes, OS updates, new features.
Apps degrade. iOS releases break things. Android OEMs ship odd versions. We offer monthly retainer engagements for ongoing fixes, OS-version compatibility updates, and incremental feature releases.
Industries We Serve
We have shipped mobile apps in domains where mistakes have
real consequences:
Healthcare
patient engagement, telemedicine, treatment compliance tools, HIPAA-aware data handling
FinTech
mobile banking, investment management, KYC flows, transaction monitoring
eCommerce
native mobile commerce, headless storefronts, loyalty apps
EdTech
learning platforms, live-class streaming, assessment tools
Industrial / IoT
remote control apps for connected hardware
Media & Social
content platforms, social networks, live streaming
The list is not exhaustive. The pattern is: we take on domains where we can develop real expertise, not generic projects bouncing between unrelated industries.
Featured Projects
DreamsCloud Mobile — social network app
Two native apps (iOS and Android) for a dream-sharing social platform. We built the registration flow, Facebook and Google+ social login, content feeds, in-app messaging, and Mixpanel-based analytics. Three specialists, five months from start to App Store.
Results: 100,000+ downloads.
AD Assist — business
chat app
Real-time messaging app for sales teams. Quickblox for chat infrastructure, integrated voice via standard phone dialers, Google Calendar API for event scheduling. Secure REST API over TLS for core operations. Native iOS (Swift, Alamofire) and Android (Java, RxJava, Picasso) builds with shared backend.
Read Case Study
Mopac — civic information app
Mobile app providing real-time updates on road repairs and construction. Native iOS and Android with shared backend. Notification system tuned for high-frequency civic alerts without becoming noise.
Read Case StudyHow We Engage
We offer three engagement models, picked based on where you
are and what you need:
Fixed-Scope Project
Best when you have a clear specification and want a predictable budget. We deliver against the spec, with a formal change-request process for scope adjustments. Common for MVPs and bounded feature work.
Dedicated Team
Best when you have ongoing product work and want a stable team that learns your codebase. We assign developers, QA, and a project manager as a unit. You manage priorities; we manage execution. Common for product companies scaling their mobile presence.
Staff Augmentation
Best when you have an internal mobile team and need to plug specific skill gaps — a senior iOS architect, an Android performance specialist, a QA automation engineer. Our developers join your existing process and tools.

In-House QA — Why it Matters
Outsourced QA is the cheapest way to ship a mobile app, and the most common reason apps lose their App Store rating in the first month.
Our QA department has been part of Uran since 2006. QA engineers report to a Head of QA, not to project managers — which means they are free to flag problems without political pressure. Every project has assigned QA from day one, not just final-week testing.
What this looks like in practice:
Test cases written before development starts on each feature
Manual testing on real devices (we maintain a device lab covering current iOS versions, recent Android flagships, and lower-spec Android phones)
Automated regression suites for any project longer than three months
Security testing for apps handling personal data (auth flows, token storage, API security)
Performance testing for apps with real-time features (chat, streaming, location)

FAQ
01
How Long Does It Take to Build a Mobile App?
Range: 3-6 months for a focused MVP, 6-12 months for a full product, 12+ months for complex platform apps. We give you a defensible estimate after the discovery phase, not before. Any vendor giving you a hard timeline without discovery is guessing.
02
Native or Cross-Platform — Which Should I Choose?
Cross-platform (Flutter, React Native) wins on time-to-market and codebase maintenance when your app is primarily UI-and-API-driven. Native wins when you need deep platform integration, advanced graphics or AR, complex offline behavior, or peak performance. We recommend based on your actual requirements, not on what is currently trendy.
03
Do you Sign NDAs Before Discovery?
Yes. Standard NDA available, or we will sign yours.
04
Who Owns the Code?
You do. We work under work-for-hire terms. You receive full source code, repository access, and CI/CD configuration. No vendor lock-in.
05
Can you Take Over a Project from Another Vendor?
Yes. We do code audits before committing to a takeover engagement so you know what you are inheriting and we know what we are signing up for.
06
What Happens After the App Launches?
You can take the codebase in-house, contract us for a fixed support package, or keep a dedicated team on retainer for ongoing development. Most clients pick the retainer model for the first year, then decide based on roadmap.
07
Do you Do App Store Submissions?
Yes. We handle App Store and Google Play submissions, screenshots, descriptions, and review correspondence as part of standard project delivery.
08
How Do you Handle Security for Apps with Sensitive Data?
Security review is part of our QA process for any app handling personal, financial, or health data. We follow OWASP Mobile guidelines, implement secure token storage (Keychain, EncryptedSharedPreferences), and conduct penetration testing on critical flows. For Healthcare and FinTech projects, we align with HIPAA and PCI-DSS requirements respectively.
