Your day, your air, your story.
Air Diary is the first tool in the Companera ecosystem.
See what's in the air around you without alarm bells or noisy dashboards.
Notice, gently, how outside conditions shape how you feel inside.
Small, calm notes build up into patterns you can actually use.
Your entries stay yours. No noise, no pressure, no hidden retention.
Air Diary is built for ADHD, autistic, anxious, senior, and people with sensory differences — and anyone who wants a quieter way to understand how their environment shapes their day.
Human AQI is a future layer of Air Diary — a gentle way to understand air quality through lived experience. It is not a separate app.
It is the next step in the same journey: helping people notice how air and comfort connect. Human AQI will build on the daily entries you already make in Air Diary, turning lived experience into a clearer picture of comfort and environment.
It stays fully inside the Companera ecosystem.
Open the app in a new tab and start with a single, gentle entry.
