Project overview
Aeris Health was created to help users better understand the relationship between indoor air quality and personal wellbeing. While air quality data is often presented through technical metrics, the goal was to create a more human-centred experience that translates environmental information into meaningful insights and actionable recommendations.

The project focused on making complex air quality information accessible, helping users monitor their environment, identify potential risks and take simple actions to create healthier indoor spaces.
Challenge
Most users do not understand technical air quality measurements or how environmental conditions affect their health. Information is often presented through complex data points that provide little context or guidance.

The challenge was to transform environmental data into clear, actionable insights that help users understand their surroundings and make informed decisions about their wellbeing.

Solution
The experience was designed to bridge the gap between environmental data and everyday decision-making. Air quality information was simplified and presented through intuitive visualisations, helping users quickly understand current conditions and their potential impact on wellbeing.

The platform combines monitoring, insights and recommendations into a single experience that supports healthier habits and greater environmental awareness.

Key Decisions
Making air quality data easier to understand
The experience focused on translating technical environmental data into information that users could quickly interpret and act upon.
Encouraging habit-based monitoring
The dashboard was designed to help users regularly check and understand changes in their indoor environment rather than only interacting with the product when problems occurred.
Balancing information and simplicity
Environmental data can become overwhelming. The interface prioritised the most relevant metrics while keeping secondary information accessible when needed.
Outcome
The redesign delivered measurable improvements in usability and engagement. Wait times between screens dropped noticeably, making everyday use faster. A 15% increase in users engaged with advanced features, including personalised scheduling directly from the app. Post-launch feedback showed a stronger user–app relationship overall, with 65% of users specifically valuing the AQI education content that helped them get more out of the product. What travels forward: information that empowers users beats information that just informs them — the AQI content wasn't a feature, it was the reason users kept coming back.

By focusing on understanding rather than raw data, the experience helps users make more informed decisions about their health and indoor environment.
