the app is very finicky, unfortunately. I have a Samsung s21. mostly the app works. sometimes it doesn't connect. right now at the time of being asked to review it, it is not working! very frustrating sometimes. Edit: to respond to the manufacturer -- no, the cache doesn't solve issues. It's a very finicky device and app. I'm rather disappointed by the reliability. It's too bad, it's an expensive tool and it's not very reliable. Wish this could be better. Disappointing.

Overall the app and monitor seem easy to use. The main problem I have revolves around gps tracking. The downloaded results often are missing geolocation data or have inaccurate data even when I select precision gps mode with continuous sampling. Tracking for mobile use was an important reason I bought the thing.

The app connects well and runs fine on the Samsung S9. The only thing that needs a rework are the graphs. While the history can be broken down into hours, days and weeks it does so in chuck's that make it hard to interpret. The app does have an export to Csv. I wish the app could just open in excel. Once I reviewed the file on my desktop, I was able to clearly see that certain rooms and the garage had decisively higher levels of particulates. I could not tell that from the app.
