EOF YOMI LABS LTD designs, builds and maintains cross-platform applications — mobile, desktop and browser — together with the backend services and network infrastructure that power them. Privacy and security are part of the design, not an afterthought.
From the first prototype to store release and long-term maintenance — one team owns the client apps, the backend and the infrastructure.
Native-quality iOS and Android apps built with Flutter, with platform code in Swift and Kotlin where performance or system integration matters.
Windows, macOS and Linux clients with native C++ components, background services, signed installers and automatic updates.
Lightweight, permission-minimal extensions for Chromium-based browsers and Firefox, built on Manifest V3 and published to the official stores.
Typed, well-tested APIs and account systems: authentication, subscriptions and payments, real-time updates and admin tooling.
Secure transport, encryption and privacy-preserving architecture. We design systems that collect as little data as possible.
Automated builds and releases, infrastructure as code, monitoring and alerting — so products stay fast and available after launch.
Alongside client work we develop our own products — that is where we test our tools and practices first.
A privacy-focused secure connection app. One account works across phones, computers and the browser, with a simple interface and modern encrypted protocols under the hood.
We partner with startups and companies to design and deliver their products — or take over and modernise existing ones.
We choose mature, well-supported technologies so that what we build is easy to maintain for years.
Short iterations, working builds every week and clear communication at every step.
We clarify goals, users and constraints, and agree on scope, milestones and success criteria.
Architecture, data model and interface design — reviewed with you before a line of production code.
Iterative development with automated tests, code review and test builds you can install on your devices.
Store submission, monitoring and regular updates — we stay with the product after launch.
