How we can help

From an idea on paper to an app published on the App Store — in one place, with no middlemen.

Our own apps

We design, build and grow our own iPhone and iPad products — from the first sketch to updates on the App Store.

Custom apps

A native iOS app for your company or your customers: SwiftUI, clean code and full rights to the source code when we’re done.

Integrations & data

We connect apps to business systems: APIs, SQL databases, KSeF, ERP. Financial data integration is what we do every day.

MVP & consulting

Got an idea? We’ll help you narrow it down to a first version you can quickly test with real users.

How we work

From idea to App Store in four steps

  1. Conversation

    We learn about the problem, the users and the goal. Together we decide what the first version must include.

  2. Prototype

    A clickable screen design — you see the app before a single line of code is written.

  3. Build & test

    Short iterations and TestFlight builds you install on your own iPhone.

  4. App Store & beyond

    Release, listing copy and screenshots — then updates and improvements based on feedback.
