Very mediocre app I would say being working I. The tech industry. This app don’t connect with the device which I can manage refreshing it repeatedly to make it work. The problem is when I sync the device new data do not get uploaded. It show be the data which was older. I delete all from the app and then it load the new data but I can’t be doing this every time though not sure it works. I expect more from such a company dealing with medical equipment where data is key. The only way I could know the stat is by looking at this app. My understanding is that the device itself don't show it? Looking forward to get a newer app sooner which address this important need.

This is a complete waste of time and energy. Not sure why they even bothered making this app. I've had 3 nights out of a week that's it's recorded my sleep. Every night I've used it I make sure my CPap is connected and in the morning, Nothing.I've deleted the app.Don’t waste your time.

App will not update data unless you delete and reinstall app. I know the data is on the machine, since I can connect with the usb cable to my computer and see all data. Really hope that Breas will come up with an app that works consistently. Love using my Z2 Auto.

As previous reviewer mentioned, the app will not update the data, it’s false advertising that is does have a fully functional Bluetooth interface.Mechanically, the machine works ok if this is the only thing you are looking for.
