Air Quality Journal & Log

Air quality numbers are simple to see and easy to forget. Air Quality Journal keeps your personal record, tied to the places where you actually spend time. WHAT YOU RECORD • Location • The AQI reading • Action taken • A brief note WHY YOUR OWN LOG A public index shows the current readings. Your log indicates if your bedroom is usually worse than your office. FIND IT LATER History is organized by day and can be searched. YOUR DATA STAYS YOURS Records are saved on this device. No account, no server. Export to CSV anytime. WORKS OFFLINE No internet connection needed. WHY A JOURNAL AND NOT AN INDEX A public air quality index shows you the city average right now. Your personal log reveals that the bedroom is often worse than the kitchen and that opening the window on a rainy day helped. That’s the difference between a number and an actionable insight. WHAT PEOPLE USE IT FOR • Deciding whether to use the air purifier tonight • Showing a landlord that one room is worse • Checking if a new filter made a difference
