No Windows Phone App
Best Uses
Had 4 of them. One kept saying it had a bad sensor. Reset it and it was ok for another month. Every month another one would spout off there is smoke when there wasn't any. You need an IOS or Android device to set them up and does not support Windows Phone. Luckily I am able to send them back and get a refund since the product had a recall because of the 'hand wave' to silence feature.
How long have you owned it:

No, I would not recommend this to a friend.
