Logo Design Illustration Healthcare App Design

Illustrating Sleep Health

For EnsoData’s Celeste+ app, I created the logo, app icon, and illustrations that help patients confidently navigate at-home sleep testing. These visuals established a clear, approachable style that continues to guide their product experience.

Scope

I worked as a freelance design consultant, focusing exclusively on the visual identity and illustrations for the Celeste+ app.

Logo & App Icon

Created the Celeste+ logo and app store icon to establish a clear, recognizable brand identity across platforms.

Custom Illustrations

Developed vector illustrations that guide users through device setup and usage, inspired by simple, instructional design styles like Lego and IKEA manuals.

Masked Product Shots

Prepared, cleaned, and exported product/device images at multiple sizes for integration into the app alongside the custom illustrations

UI/UX design and app development were not part of my role.

This scope ensured my contributions stayed highly focused while still delivering lasting brand assets for the app.

My Approach

I collaborated directly with Ensodata’s Senior Marketing Director, Rachel Boer, following a clear step-by-step consultancy process for each project:

01. Brief & Estimate

I received Rachel’s requests and drafted a clear scope of work with defined revision terms.

02. Exploration

I developed multiple visual concepts, especially for the first illustration set, to establish a consistent style direction.

03. Refinement

I refined the designs through iterative rounds of feedback and communication with Rachel and her team.

04. Delivery

I exported final files in multiple sizes and packaged them for seamless integration into the app.

This structured process allowed me to deliver high-quality assets efficiently while adapting to Ensodata’s evolving project needs.

Logo & App Icon

One of the tools I used during my process was the InVision prototyping software. It helped me visualize the UX and streamlined my own processes while building out my concepts for the Logging Seizures application. InVision learned of my experience and asked me to write about the process in a guest article on their Invision App Blog. Read the full article, now hosted on Medium.

Custom Illustrations

I created step-by-step vector illustrations to guide users through device setup, pairing, and usage. These were designed in a clean, instructional style inspired by IKEA and Lego manuals, ensuring clarity and ease of use.

Outcomes

Clear visuals for healthcare, scaled for real-world use

The final deliverables ensured Celeste+ had a consistent, scalable identity, from the logo and app icon to device illustrations used inside the app. These assets remain part of the live platform today, helping users interact confidently with their devices.
