We were contacted by CoastKey to help out with preparing a modern boat engine controller for the Internet of Things.

With growing demand in connected devices, CoastKey wanted to enable users to operate and update their boat engine controllers using a dedicated mobile app.


Within a short time, we delivered an MVP app for iOS that communicates with the boat controller using Bluetooth™ technology. It can send and receive signals to switch the engine on/off, change speed, direction, monitor batteries and update the controller firmware.

The User Interface was designed with simplicity and familiarity in mind, to provide users with a seamless transition from the physical buttons they used on the controller device.

To support firmware updates, we also created a back-end service in .NET, called through an API on request.
