Mobile apps with a cloud backend built in
We build iOS and Android apps in Flutter, backed by serverless services on Google Cloud. As a Premier Google Cloud Partner, we handle both the app and the backend it depends on, so you deal with one team.
What we build
One Flutter codebase for every device
Separate iOS and Android codebases double the work and the technical debt. We build in Flutter, which gives you:
- Smooth rendering: Compiled to native ARM code and drawn by the Impeller engine at 60 to 120 frames per second.
- Consistent design: The same UI on iPhone, iPad, Android phones and tablets, and foldables.
- Native hardware access: Platform channels to Apple HealthKit, Google Fit, Bluetooth Low Energy (BLE), NFC, the camera and biometric secure storage.
Offline first apps
Field workers, clinicians and logistics staff often work with poor or no connectivity.
- Local storage: SQLite or Isar databases let users read, write and finish workflows offline.
- Sync without data loss: Conflict free replicated data types (CRDTs) sync changes with Firestore and BigQuery when the connection returns, resolving conflicts across devices.
Serverless backends on Google Cloud
- Cloud Run APIs: Go or Python services that scale automatically, including down to zero.
- Firebase Cloud Messaging: Targeted push notifications triggered by user activity.
- Vertex AI: On device and cloud generative AI, OCR document scanning and speech to text.
How we deliver
- Discovery and UX: Figma prototypes tested with real users and against accessibility standards (WCAG 2.1 AA).
- Engineering sprints: Two week sprints with automated builds on GitHub Actions or Cloud Build, distributed to testers through Firebase App Distribution and TestFlight.
- Automated testing: Integration tests across a range of physical devices on Firebase Test Lab.
- Launch: App Store and Google Play submissions, metadata, privacy manifests and compliance checklists.
- Monitoring: Ongoing observability with Google Cloud Observability, Firebase Crashlytics and performance monitoring.
