air-Q

I really wanted to like this

The app is incredibly slow and buggy. Feels like something out of the 1990s. Every time I want to view a graph, it takes ages and ages for it to load. Sometimes random pieces of data will be missing. Sometimes the time on the graph would stop a few hours short of the current time. If I try to load anything up from a year ago, it simply stays there loading for like 10 minutes, and then… blank. Hygrometer on the device itself reads too high.

air-Q is the only consumer product with comprehensive sensing and monitoring

I spent days researching products that can monitor a range of air quality measures and perform detections of multiple nuisance—and even dangerous—air components, and shy of building my own sensing platform or buying lab-grade equipment, air-Q was the only consumer product with a wide range of capabilities. You can customize and add a variety of different sensors, and you can even purchase a “scientific”model with API access. The application is well-designed, provides optional and free cloud and AI access, and provides home automation-like remote alerts for smoke, fire, and carbon monoxide (plus the sensor can be setup as a local alarm). There were no stability or other issues encountered with the app. Excellent product that ships quickly from Germany and an equally excellent app. Very pleased with this product purchase.
