Responding to user feedback, Local Haze has a new search by location feature to improve the app’s user experience and make it easier to locate air quality (AQ) sensors. In addition, the scalability of the map view has been improved with sensor site clustering.

With this new release, Local Haze continues to help air quality enthusiasts be more confident about their local outdoor air quality readings by improving the quality of sensor accuracy through crowdsourcing.

The new search UI in the Local Haze app (left) lets users enter the name of a location, an air quality sensor name or a zip code to see sensors for that location. When there are many sensors in a geographic region, Local Haze now displays an aggregated visual “pie chart” of colors representing clustered sensors’ air quality readings (right).

With release 1.1.0, now when you swipe down from the top of the main Sensors screen you’ll see the new search UI. Enter a specific sensor’s name, location or a zip code to see sensors for that specific area. After search input has been entered, auto recommendations for sensors appear in a list. Tap on a sensor in the list to see the details about that sensor’s air quality data.

With the Local Haze app, you can quickly find specific locations to check the air quality and confidence ratings or you can browse a world map to look for sensors by geographic region.

In this release, the mapping interaction for Local Haze includes several improvements around map scaling and visualizations of large numbers of AQ sensor sites. Now when there are numerous sensors in a geographic region, the user sees an aggregated visual “pie chart” of colors representing clustered sensors’ air quality readings for that area.

About Local Haze

Local Haze crowdsources and analyzes readings from a variety of outdoor air quality sensors to help users understand the air quality of the world around them. Local Haze reads AQ data from sensors from PurpleAir, AirNow, and the U.S. Department of State. Local Haze is available for free on the Apple App Store (for iPhone) and can be installed here.

Our goal is to deliver the best possible air quality confidence ratings for people using Local Haze. We are continuing to improve the search experience and the analytics around AQ sensor data to help people understand the air quality readings for the locations and gain a sense of confidence about the accuracy about their AQ sensor readings.

The Local Haze team hopes you find this new search UI and mapping enhancements useful and we welcome all feedback at localhaze@humanlogic.com. Follow updates for Local Haze on Twitter at @localhaze.
