So heres my honest thoughts: I often have to reset the app in order to login sometimes which can be a slight inconvenience. One of my biggest complaints is every time we have a power surge, I have to manually restart the camera router otherwise it remains in the off position. The app itself works great and Ive even used the camera to watch our main living area while we were away. Summer needs to update the app to work better with newer iPhones better. This app functions on my 6S Plus, albeit not perfectly.
