This app can control air quality sensors, type that is visible on Bluetooth network with names beginning with 6003#. There is Android app for this, but why use Android when you can use Windows? :) And this app has some features not present in official Android app (but, of course, also lacks some of functionalities).

App doesn’t use Internet - it doesn’t send your data, it doesn’t require you to create any account, etc. Your privacy is valuable, and I don’t want to compromize it.

Main functionality of this app is download data from app, and export it. Every measurement downloaded from device, is saved in text file. On desktop, you can access this files clicking on Explorer button on MainPage. On phones, these files are created on your SD card, in folder Datalogs\AirBox, subfolders for year and month.

App can work in background, retrieving data every 30 minutes. This data is then compared with warning and alarm levels, and if such level is crossed, app sends you notification (in form of Toast). As data is stored in Roaming form, one instance of app (e.g., on desktop) can retrieve data, and another instance (e.g., on phone or laptop) can show this data for you.

If you want charts, please export data to e.g. Excel - use History page, read data, copy to clipboard; then in Excel - paste into worksheet. Or use log files, created by app.
