Two ways to work together
Software delivered with hardware
One team develops the hardware and software. We agree on communication protocols during design, develop firmware, apps and backend systems in parallel, and test them together on the device.
Independent software projects
For existing devices that need a companion app, an app rebuild or a backend system, we start by reviewing the protocols and agreeing on the scope. We also account for device constraints such as Bluetooth timing and power consumption.
Software delivery process
We agree on device, app and backend interfaces before development and integration testing.
- 01
Requirements & prototypes
Review user workflows and agree on screens and features
- 02
Protocols & interfaces
Agree device, app and cloud interfaces first
- 03
Parallel development
Develop firmware, apps and cloud platforms together
- 04
Hardware & software integration
Test communication, data handling and functions on real devices
- 05
App release & deployment
App store publication and platform deployment
- 06
Iteration & maintenance
Version updates, platform compatibility and issue response
Frequently asked questions
Do you take software-only projects?
Yes. We can start with communication protocols for existing devices that need apps or data platforms. For older products without documentation, we can analyze the protocols before development.
Who owns the app accounts and servers?
Developer accounts, hosting, source code and third-party component usage are agreed before work begins. We provide submission, deployment and handover materials within that scope.
Can you develop only firmware for our software team?
Yes. We can deliver firmware, apps or cloud platforms separately, aligning interfaces with your team's requirements.
How does ongoing maintenance work?
We can discuss maintenance by release or by period, with the support scope, platform updates and deployment responsibilities agreed in advance.
