London software studio
Mobile apps and the systems behind them.
Rozemyne designs, builds, and maintains iOS apps and the backend services that power them — one accountable team from first sketch to shipped release.
About
Founded in London in 2024, Rozemyne is deliberately small. No account managers, no hand-offs — the people you talk to are the people who build. We take on a few projects at a time and see each one through, from architecture to the App Store.
What we do
- 01
iOS & mobile development
Native apps built with Swift and SwiftUI — fast, accessible, and comfortable on every screen size. From prototype to App Store release, and the updates after.
- 02
Backend & SaaS
APIs and services that stay up and stay simple: Elixir, Phoenix, and PostgreSQL on infrastructure you control. Built for years of low-drama operation.
- 03
Product & interface design
Real screens early, design systems that survive contact with development, and interface copy that says what it means.
- 04
Care & maintenance
Releases don’t end projects. We monitor, patch, localise, and keep software current with new OS versions — so what we ship keeps earning trust.
How we work
Ship small, ship often
Working software every week beats a big reveal every quarter.
Boring where it counts
Proven tools, few dependencies, honest estimates. Excitement belongs in the product, not the stack.
Built to hand over
Documented, tested, and explained. If we vanished tomorrow, your team could carry on.
