A mobile software studio from Latvia, building for the long run.

Why we exist

Most people experience software through a phone. A good mobile app disappears into daily life: it opens fast, it does one thing clearly, and it keeps working after the next OS update. A bad one gets uninstalled within a day. We started Quattrotrend to make more of the first kind.

We began with our own product, Unicnet, an app that maps publicly available restrooms and essential facilities. Building it from scratch — the Android and iOS apps, the Firebase backend, the web app, the store listings and the legal documents — taught us what it really takes to ship and operate a mobile product. We now offer that experience to companies that need an app of their own.

What we do

• Native Android apps in Kotlin and Jetpack Compose.
• Native iOS apps in Swift and SwiftUI.
• Cross-platform apps in Flutter when one codebase is the better choice.
• Backends on Firebase and Google Cloud: authentication, data, storage, notifications, functions.
• Product and UX design, from research to clickable prototypes.
• Store launches, analytics and long-term maintenance.
