5 stars: All the negative reviews I have been reading seem to be user error or just lack of understanding how the app works. I have had zero crashes and app works perfectly fine.
5 stars: i used to hate the whole c4 system but having sacked 4 useless installers i finally came to one genius engineer who simply installed it the way it should have been done from the start. if you cant get it to work the chances are your Wi-Fi needs improving.... or you just need to call Lewis Light and Sound. C4 is great but it needs a good installer and most of the ones I've met so far are cowboys and incompetent
4 stars: good app. an interface update would be good with a more modern and simplistic setup. launch time should be made quicker too. don't trust the negative reviews on here, they're from those that are bit backwards on how the app is supposed to work.
4 stars: Video Overview button, on the first screen, is broken. The button acts as if it's been clicked, but does not go anywhere.
5 stars: The smartest system ever had... Its so fast and improved alot.....
4 stars: Works great on our cell phones, but not our note 10 tablet. Perhaps it's too old.
4 stars: Guys. This is the most perfect and good app ever in house and homes. It is the best and easy to use for beginners.
5 stars: Best Smart Home system around. Great value and products. Unimaginable that \nevery home doesn't have Control4. I guess there dumb homes for dumb people..
5 stars: Great App with ver...
