Product Engineering &
Custom Development

The studio designs and builds custom iOS, macOS and tvOS apps for clients, from a focused single-purpose tool to a full product, with user experience first and the jobs-to-be-done methodology behind every decision.

Swift

  • SwiftUI
  • UIKit
  • Swift Concurrency
  • Foundation Models
  • WidgetKit
  • Live Activities
  • App Intents
  • SwiftData
  • HealthKit
  • WeatherKit
  • MapKit
  • EventKit
  • Vision
  • Charts
  • Core Motion

And the parts that are not the app: authenticated REST APIs over FastAPI and PostgreSQL, offline sync and sharing built on CloudKit, and releases run through App Store Connect.
