Software development & mobile apps
We build software around how your team actually works. That means web platforms, internal tools, admin dashboards, and native mobile apps for iOS and Android. Not a generic product you have to force your processes into.
Mobile app development is a core part of what we do. We've shipped visitor apps, staff apps, loyalty apps, and ticketing apps that people use every day. At Cantacuzino Castle, the apps were the heart of the project: visitors bought tickets on their phone, scanned QR codes at the entrance, and staff managed daily operations from connected mobile tools. The castle went from offline ticket booths to a fully digital flow, and the numbers followed. Over €250,000 in revenue in the first six months.
We've done the same kind of work at different scales. Snap-on got an enterprise logistics platform for aerospace and industrial environments. HCLTech got a full custom e-learning platform. MAM Bricolaj got a native loyalty app that hit 7,500 active users in four months.
We scope before we build, communicate throughout, and deliver software you can run in production. Not a demo that dies after launch.
Problems we solve
- Off-the-shelf tools that force your team into someone else's workflow
- Mobile and web experiences that do not talk to the same data
- Projects that stall after a demo because production was never planned
- Scattered spreadsheets and manual handoffs instead of a real system
Who this is for
- Operators who need custom platforms, not another SaaS subscription
- Teams shipping visitor, staff, loyalty, or field apps
- Companies that need web and mobile connected to the same backend
- Founders and IT leads who want scoped delivery with clear ownership
What we deliver
- Native iOS and Android mobile app development
- Visitor apps, staff apps, ticketing, and loyalty apps
- Custom web platforms and internal business tools
- Enterprise integrations and API design
- Admin dashboards, ERP-style workflows, and reporting
- User access, roles, and multi-tenant architecture
- Ongoing maintenance, iteration, and feature expansion
Technologies & stack
- TypeScript, React, Next.js
- Node.js and modern backend APIs
- PostgreSQL, Supabase, and cloud databases
- Native mobile (Swift, Kotlin / React Native where appropriate)
- Docker, CI/CD, and cloud deployment (Vercel, AWS, GCP)
How we work
- 01Discovery: map workflows, constraints, and success criteria before writing code
- 02Architecture: define data model, integrations, and delivery phases
- 03Build: ship in increments you can review and put into real use
- 04Launch and iterate: harden for production, train users, and expand features

Frequently asked questions
Do you build both web and mobile, or only one?
Both. Many projects need a shared backend with web tools for operations and native or cross-platform apps for visitors, staff, or customers. We design them as one system.
Can you work with our existing systems?
Yes. We regularly connect new software to CRMs, ERPs, payment providers, and internal APIs so you do not replace everything at once.
How do you avoid building something that never launches?
We scope for production from day one: environments, access control, monitoring, and a rollout plan. Demos are checkpoints, not the end product.
Where are you based and who do you work with?
Athryx Tech is based in Romania and works with local and international teams. References include Cantacuzino Castle, Snap-on, HCLTech, and MAM Bricolaj.
