What we do
Mobile development services
Native, cross-platform, new or existing — every engagement includes the testing it takes to ship reliably.
iOS Development
Native iOS apps built to Apple platform guidelines, from the first release through ongoing App Store updates.
Android Development
Native Android apps that behave consistently across the wide range of devices and OS versions your users have.
Cross-platform Development
One codebase for iOS and Android when it fits your product, with platform-specific work where it matters.
Mobile MVP Development
Scope the core flows, build them properly, and get into users’ hands without a codebase you will need to rewrite.
Existing App Development
New features, fixes, and regular releases for apps already live in the App Store or Google Play.
Mobile App Modernization
Stabilize and update aging apps: dependency upgrades, refactoring, and performance work backed by regression coverage.
Mobile Integrations
APIs, authentication, payments, push notifications, analytics, and third-party services, wired in and tested end to end.

Mobile QA
Tested where your users actually are
Mobile apps face risks web apps never see. We check behaviour across the conditions that break real installs — not only on a developer’s phone.
Screen sizes
OS versions
Real devices
Emulators & simulators
Network conditions
Permissions
Background & foreground
Push notifications

How we deliver
From idea to a maintained app
Eight steps, each with a clear outcome. Testing starts long before the release candidate.
01
Discovery
We clarify goals, target users, and platforms, and agree on what the first release must do.
02
UX & Requirements
User flows and acceptance criteria written so developers and QA share one definition of done.
03
Architecture
Native or cross-platform, backend and API design, offline and sync behaviour — decided before coding starts.
04
Development
Iterative builds you can install and try, with code review on every change.
05
Continuous Mobile QA
Manual and automated testing across devices and OS versions in every sprint.
06
Beta & Release Testing
Beta builds for real users, crash monitoring, and release candidate validation.
07
Store Release
Builds, store listings, and review requirements prepared so submission goes smoothly.
08
Maintenance
OS updates, fixes, and new features after launch, with regression checks on every release.

Engagement models
Pick the setup that matches your app today
Teams often start with one model and shift to another between launch and maintenance.
Full Mobile Product Team
Mobile developers, QA, and backend support delivering the whole app with one accountable team.
Dedicated Mobile Developers
iOS, Android, or cross-platform engineers working exclusively on your product.
Team Extension
Mobile engineers joining your in-house team inside your tools and process.
Mobile Development + QA
Development paired with dedicated mobile QA, so every release is tested across devices.
Existing App Support
Ongoing fixes, OS updates, and improvements for an app that is already live.
Why GenSoft
Mobile development and mobile QA, one team
From the first build to long after launch — the people who write the app are in the same sprint as the people testing it.
Development and QA, One Team
Mobile developers and QA engineers work in the same sprints, so device issues are fixed before they reach the stores.
Reliable Releases
Quality from day one and strong mobile testing expertise mean fewer crashes, fewer rejected builds, and fewer hot-fixes.
Flexible, Continuous Support
Scale the team up for a launch and down for maintenance, with continuous support for OS updates and new features.
Case studies
Selected work
