BLE control app development
Developing an app to support cutting edge live music performance
We partnered with Alto Professional to build a mobile app that unlocks the full potential of their speakers and amplifiers.
Connected products need more than basic app development
Mobile apps for Bluetooth
and connected devices
Build apps that reliably connect to real products.
We design and build mobile apps that communicate with physical devices over Bluetooth (BLE), including consumer products, audio equipment, and custom-built hardware where the app is a core part of the product experience.
Our focus is simple: make the connection reliable, usable, and maintainable in real-world conditions.
Bluetooth App Development
Built around the app and device together
We go beyond basic connectivity and build the full interaction layer between app and device.
Working alongside Azuki has been a real pleasure. They delivered us a fantastic product, and their expertise and problem solving were invaluable as we moved through the different stages of the project.

This kind of work sits in the gap between mobile product delivery, hardware integration, and long-term platform thinking.
The app has to be clear for users, dependable in poor conditions, and structured so the communication layer still makes sense when the product line grows.
That usually means close coordination with hardware teams and embedded engineers, not just building screens around an unfinished protocol.
Where this is typically used
- Companion apps for connected products
- Control apps for audio equipment and embedded systems
- Multi-device ecosystems with a single app interface
- Products where configuration, control, or monitoring happens via mobile
What we actually do
We build the communication layer, the control experience, and the surrounding app behaviour so the product continues to work once it leaves ideal test conditions.
BLE communication and integration
- Device discovery, pairing, and reconnection
- Stable communication under real-world conditions
- Background handling and session management
Custom device protocols
- Design and implementation of BLE command structures
- Consistent communication layers across device ranges
- Abstraction that allows one app to support multiple products
Control and configuration interfaces
- Real-time control of device behaviour
- Structured configuration flows
- Clear feedback between device state and user interface
Firmware update support (OTA)
- Over-the-air update flows via mobile
- Version handling and rollback considerations
- Reliable update processes for deployed devices
Where projects can go wrong
- The Bluetooth connection is unreliable outside ideal conditions
- The device protocol is unclear or inconsistent
- The app works in testing but breaks in real usage
- Supporting multiple device variants becomes difficult
- Firmware updates are risky or manual
These are not edge cases. They are common outcomes when this work is treated as standard mobile development.
How we approach it
We treat the app and device as a single system.
- Designing the communication layer early
- Handling edge cases like reconnection, failure states, and partial data
- Building for long-term support across device versions
- Keeping the system understandable for future updates
The result is software that continues to work as the product evolves.
