Mobile app development outsourcing
Athryx Tech is a mobile app development company in Bucharest, Romania, that companies across Europe, the UK and the US hire as their outsourced or nearshore app team. We design, build and ship native iOS and Android apps and the backend behind them, with one team accountable from scope to store release.
Romania is one of Europe's established software outsourcing destinations. Working with us means a team inside the EU, on Eastern European Time, one or two hours ahead of London, Berlin, Zurich or Copenhagen, with afternoon overlap into the US East Coast morning. You get GDPR by default, English-speaking engineers and direct access to the people building your product.
We have delivered for international clients at different scales: an enterprise logistics platform for Snap-on, a custom e-learning platform for HCLTech, and the visitor and staff apps behind Cantacuzino Castle's digital operation. MAM Bricolaj's loyalty app reached 7,500 active users in four months.
Outsourcing only works when responsibilities are clear. We agree up front who owns the code, repositories and store accounts, document as we go, and leave you free to grow the team, bring development in-house or keep us on for maintenance.
Problems we solve
- In-house hiring that takes months while the roadmap waits
- Offshore vendors in distant time zones with slow feedback loops
- Freelancers who disappear after launch, leaving code no one can maintain
- Apps that pass the demo but fail store review or real-world use
Who this is for
- Companies in the UK, DACH, the Nordics, Benelux and the US looking for a nearshore mobile team
- Startups that need a production app before building an in-house team
- Romanian companies that want to outsource app development to a local, accountable partner
- Product teams that need extra iOS and Android capacity next to their own developers
What we deliver
- End-to-end native iOS and Android app development
- Cross-platform apps with React Native where one codebase fits
- Backend, APIs and admin panels built alongside the app
- UX and UI design for mobile journeys
- App Store and Google Play release management
- Project-based delivery or ongoing development capacity
- Maintenance, OS updates and post-launch iteration
Technologies & stack
- Swift and Kotlin for native apps
- React Native where a shared codebase is the right trade-off
- TypeScript APIs and cloud backends
- PostgreSQL / Supabase and secure authentication
- CI/CD for mobile builds and store submission

Frequently asked questions
Why outsource mobile app development to Romania?
Romania combines a strong engineering talent pool with EU membership, GDPR, widely spoken English and a time zone that overlaps with Western Europe and part of the US working day. It is typically more cost-effective than hiring in-house in Western Europe or the US, without the distance of far-offshore teams.
Do you work with clients outside Romania?
Yes. We work in English with international clients, including Snap-on and HCLTech, and run projects remotely with regular calls, shared boards and test builds.
How do you keep an outsourced project on track?
A written scope before we build, short delivery increments, test builds you can install on your own phone and one point of contact who knows the project. You see real progress, not just status reports.
Can you take over an existing app?
Yes. We start with a code and infrastructure review, fix what blocks releases, then continue development or maintenance.
How much does a software project cost?
It depends on your needs and budget. Small apps and MVPs can start from around €3,000–5,000, while larger mobile apps and business platforms we delivered recently cost €15,000–21,000. You can also choose a monthly model from around €1,000 per month over 12–24 months, with maintenance included.
