Companion apps that make a device a product
For most users the app is the product: pairing, control, data, updates and subscriptions all happen there. I design and build this layer around your device and SDK.
Capabilities
Technical capabilities
Everything a device app needs — from the radio link to the subscription.
iOS / Android
Native or cross-platform apps chosen by the product's needs, published in global and local app stores.
SDK Integration
Your device SDK wrapped into a clean, tested layer the app and future products can reuse.
BLE / Bluetooth
Pairing, reconnection, background sync and battery-friendly data exchange.
Device Communication Protocols
BLE GATT, Wi-Fi, MQTT and custom binary protocols — documented and covered by tests.
Firmware API Integration
Commands, settings, OTA firmware updates and diagnostics through the firmware API.
Cloud Synchronization
Device data in the cloud, available across phones and accounts, with offline mode.
Push Notifications
Alerts and reminders through APNs, FCM and providers that work where FCM is unavailable.
Authentication
Accounts, sign-in with email, phone or third-party providers, family and device sharing.
Subscription Management
Plans, trials and premium features with app-store and web payments.
The stack is chosen for each project; the list shows typical technologies, not a fixed set.

Tools and platforms
- Swift / Kotlin
- Flutter / React Native
- BLE GATT
- MQTT
- REST / gRPC
- APNs / FCM
- OAuth 2.0
- In-app purchases
- CI/CD
Native or cross-platform?
It depends on the device and the team: native for heavy BLE work and the best battery life, cross-platform for faster delivery to both platforms.
Can the app be white-label?
Yes. One code base can be configured and rebranded for several device lines and customers.
Next step
Building a device that needs software, AI or a market?
