Your app, your way.
Built to ship.

We build what you need, on the stack that fits. Flutter + Firebase is our preferred approach, but we work with your existing codebase, platform preferences, and infrastructure. Data pipelines from users to analytics.

Flutter + Firebase preferred.
Your stack if you need it.

Our preferred stack is Flutter + Firebase — one codebase producing native iOS, Android, Windows, and macOS binaries. Firebase provides authentication, Firestore real-time database, and cloud storage. But we adapt to client needs: legacy codebases, platform-specific requirements, or existing infrastructure.

When we need to get close to the hardware, we develop native iOS (Swift) and Android (Kotlin) Flutter plugins — for wearable sensors, Bluetooth devices, and platform services like Apple Health and Google Health Connect.

Every app is instrumented for analytics from day one. Firebase Analytics tracks screen navigation, feature usage, and user engagement. Custom event logging captures study-specific interactions. On the backend, Python scripts using the Firebase Admin SDK extract and aggregate Firestore data to CSV — ready for your statistician, R script, or publication pipeline.

  • Cross-platform: iOS, Android, Windows, macOS from one codebase (or native if needed)
  • Firebase Auth with role-based access (researcher, clinician, participant)
  • Firestore real-time sync — works offline, syncs when connected
  • Firebase Analytics — screen navigation, feature usage, engagement tracking
  • Custom event instrumentation — study-specific interaction logging
  • Python data extraction pipeline: Firestore → aggregate → CSV
  • Backend statistical analysis in R — automated reporting pipelines
  • Ethics board approved — PIPEDA and Quebec Law 25 compliant
  • Wearable sensor integration (accelerometer, gyroscope, magnetometer @ 100Hz)
  • Apple Health & Google Health Connect integration
  • Native Swift (iOS) and Kotlin (Android) Flutter plugins for hardware access
  • Speech and voice analytics (emotion detection)
  • Custom hardware — circuit design and embedded C firmware
