Android, iOS, web and desktop from one Kotlin codebase
Most companies pay separate teams to build the same app twice. We think that money is better spent elsewhere. Ernst & Conte is a Swiss software consultancy that designs, builds, and maintains Android, iOS, web, and desktop applications from a single Kotlin codebase. Fewer handoffs, faster releases, and one team that stands behind the result.
What We Do
We take on new products, ageing codebases and projects short of people, from architecture to production.
Kotlin Multiplatform
One shared codebase for Android, iOS, desktop, and web. Your users get fully native apps. You pay for one implementation, and every fix reaches all platforms at once.
App Development
From a first prototype to a banking app with 150,000 users, we build Android and iOS applications that are ready for production. Native where it matters, shared where it saves you money.
Fullstack Development
Apps rarely come alone. We build the backends, web frontends, and cloud infrastructure behind them, along with the CI/CD pipelines that get releases out the door reliably.
AI Integration and Automation
AI where it pays off: automated reviews and routine steps in your development process, assistants built on your own data, and the infrastructure to run them. On our cloud or on your own servers, as regulated environments require.

Marc's profileTessa: end-to-end tests in plain language
Tessa explores your app, maps the screens and flows it finds, and drafts plain-language test scenarios for the ones nobody is testing. It runs them on your phones, simulators, browsers and desktop computers and hands you screenshots and logs for every step. No test code to write, none to maintain.
More about TessaA 24-second film without narration. A scenario, “Edit transfer amount before approval”, is drafted in four plain-language steps and accepted. Tessa runs it on an Android phone in MyBänkli, our demo banking app, and the fourth step fails. The report shows the expected and the observed behaviour next to the captured screen.
