SCOPE
Onboarding + Dashboard
Overview
Aerovu is a mobile health platform that helps people with asthma and COPD track symptoms, manage medication, and follow doctor-prescribed action plans. It was built by Evrone (Flutter + Rails).
I joined the project in its late stage, after most of the core product had already been built by a previous designer. My job was to pick up the existing direction, design the parts still missing, and keep the product visually and functionally consistent as it moved toward release.
The Challenge
Asthma and COPD have no cure, only management — and most patients are never properly taught the difference between control and rescue medication. Aerovu set out to close that gap with a mobile app for tracking triggers, symptoms, and inhaler use, and for following a doctor-prescribed action plan.
By the time I joined, the product direction, visual language, and most core flows were already defined by a previous designer working with the Evrone team. The challenge for me wasn’t starting from a blank page — it was understanding an existing system quickly, finishing the onboarding and dashboard experiences to the same standard, and staying tightly aligned with engineering, product, and QA as the app moved toward release.
My Role
01 · Get up to speed
Audited the existing UI kit, flows, and previous designer’s decisions to understand the visual language and interaction patterns already in place.
02 · Design in context
Designed the remaining onboarding steps and the daily dashboard, matching existing components while filling gaps in states and edge cases.
03 · Collaborate closely
Worked directly with Evrone’s engineers, the product manager, and QA engineers in weekly syncs to keep design, build, and testing moving together.
04 · Refine with QA
Reviewed builds against designs, fixed inconsistencies flagged by QA, and adjusted for real device and data edge cases before release.
ONBOARDING
Getting new users set up with confidence
New users sign in with their phone number, then complete a short profile: personal details, followed by medical information — condition, control level, and which devices they use (inhaler, peak flow meter). This lets the app tailor tracking and reminders from the very first session.
DASHBOARD
A daily home base for tracking symptoms
The dashboard is the first thing users see each day. It surfaces how they’re feeling, a shortcut to log symptoms, weather that may affect breathing, and quick access to peak flow charts, inhaler puffs remaining, and rescue medication — so the most time-sensitive information is never more than a glance away.
Outcomes & reflection
The onboarding and dashboard experiences shipped as part of Aerovu’s MVP release, giving new users a clear path from sign-up to their first day of tracking. Working this late in a project — inside someone else’s design system, alongside engineers, product, and QA who already had momentum — meant success was measured less by a signature style and more by how invisibly the new screens fit in and how smoothly they made it through build and testing.
The biggest takeaway was practicing design as a form of collaboration: reading an existing system quickly, respecting its constraints, and communicating tightly enough with engineering and QA that new screens felt like they had always been part of the product.
