Easy to obtain, easy to replace
All the parts used in Calmi are off-the-shelf, meaning they're easy to find and order. They are affordable and simple to assemble.
And if any of the components break, it's easy to replace, which allowed me to experiment and learn as I'm building and testing things out.
LED light ring
A ring of twenty four light emitting pixels shine into the white SLA-printed dome, allowing for different light patterns to be created.
Speaker
Calmi can play sounds and voice-overs through its 3.5-watt speaker and dedicated audio controller.
Charging
The device runs on a lithium battery. You can charge it via the USB-port or wirelessly by using the provided charger pad.
Microcontroller
A dual-core microcontrollers served as a foundation, it has Wi-Fi capabilities and a compact form factor.
Software
The microcontroller runs on custom-written firmware. It manages communication between all components and facilitates communication between the app and the device.
The custom app has been developed from scratch. It enables users to perform complex interactions that they can't easily execute on the device itself.
Lynk & Co aims to revolutionise the car industry by providing urban people with flexible access to vehicles. They offer a monthly subscription and a car sharing platform, where users can share their cars with others to reduce costs or earn extra income.
As a designer at Lynk & Co, my colleague and I were tasked with redesigning and restructuring the mobile app from scratch. The previous app had performance issues and lacked scalability.
The redesigned Lynk & Co features a dynamic interface with easy access to all connectivity controls. It also allows non-car owners to borrow cars from other customers within the same app. The interface adapts to each user's profile, prioritising the most relevant features based on whether they own a car or not.
After analysing user feedback from testing, workshops, surveys, and forums, we identified significant usability issues with the original Lynk & Co app. Users reported critical bugs, a confusing layout, and controls buried too deeply within the app.
The chatbot, intended to connect the car and the app, was ineffective and slowed down user interactions. Additionally, car sharing was less popular than expected. Instead, users preferred easy-to-use and stable connectivity features.
To create a new app from scratch, it was crucial for the team to share a common vision. We achieved this through a series of workshops with management, the brand team, and other stakeholders, who provided valuable feedback during the concept and design process.
Connectivity was a key focus in this redesign. Customers asked for efficiency, transparency and reliability. Most connectivity features are now easily accessible on the home tab. Users can check their car's status, such as whether the doors are locked, where the car is parked, or remotely activate climate control. All located in one place without needing to dig through the app.
Before starting this project, we completed a brand redesign. We updated our design language, colour palette, and brand values. Key achievements include a flexible new colour system, design tokens and improved accessibility, enhancing both our the website and app.
We integrated these brand values into our new Design System for the app. This scalable and adaptable component library offers designers and developers a consistent foundation. With design tokens and motion documentation, it explains how components work and behave.
What sets the Lynk & Co app apart is its car-sharing feature. Like other car-sharing apps, it offers a map of available cars for non-car owners to book. Once booked, users can access the car for the agreed time. This sharing experience has been revamped and enhanced in the new app.
