Ratings and reviews

This app has been working reliably to display data from the CO2 monitor. My only complaint is that the chart displays data only from the range you tap on. If you want to view the overnight data, you have to tap "7 days," and zoom in rather than "Today" or "Yesterday" because otherwise the data on the chart starts at midnight or end at it. It would be nice if it simply displayed the data for the range in the view, then use the buttons as a convenience to snap to a particular range of the data.

Was working flawlessly until the recent update: Then the app couldn't load the time series data anymore, it was only able to show the current values. Even updating the firmware to the most recent version didn't help. I wrote this here and got the feedback to restart the sensor by removing the batteries. This resolved it (though it also deleted the old data, it seems). Thanks!

App charts CO2 and other levels reasonably enough, but there's no way to get a smartphone notification when levels exceed the risk threshold—the only option is a short "peep" from the device or a series of impractical "peeps" until levels recede. The lack of notifications means if you miss the audible alert you may not realise for hours levels are too high, and no way to send an alert to wearables either. Developer said a notification was on the to-do list years ago. How many years do they need?
