Small changes would make a big difference

The app is easy to get up and running. However, there should be a setting to disable the loud beep each time a Bluetooth connection is made. That quickly gets very annoying.

The graphing of data really misses having a time stamp on the x-axis. It makes trying to understand daily patterns painful. Even the exported data doesn’t enable time tracking easily. So the whole feature set of having trend data is really crippled by this omission.

Otherwise, very pleased with the monitor so far.

Great device but mediocre app due to lacking of timestamp on captured data

This app get basic job done. The device is the best in the consumer market. If the app could chart and export timestamp, it will make the user experience 10x better. Please add this feature in.

most reliable and accurate consumer radon detector

It’s very accurate Radon data reading. It uses a dual structured pulse ionization chamber system that can detect Radon level accurately, 95% confidence +-0.5 pCi/l, within the first 1 hour. Its base technology is NRPP certified. Easy to use. Simple UI. Strongly recommend for anyone who wants to monitor Radon at home.
