Lock App Functionality

The lock was easy to install and connect to the app. It could use some drastic improvements, like allowing two people to sign in to the account and for the app to accurately reflect if the door is unlocked or locked.
Also, the capability to lock or unlock the door while away doesn’t work sufficiently.

Room For Improvement

The lock was easy to install and the app was easy to set up. There are a couple of areas where the app could use improvement.

1) Push notifications to confirm the door is locked or unlocked

2) An on screen indicator to show the lock is either locked or unlocked.

Security issues

The app and lock were very easy to setup. However there were no directions on how to lock the door from the outside using the keypad. Also, I am not getting push notifications of when the door is locked or unlocked. I agree with most reviews the Home Screen should state whether or not the door is locked or unlocked when opening the app. The Face ID required to open the app hardly works. If you use the Face ID to open the app, then close the app, the Face ID is not engaged if you reopen the app. Makes me feel a bit unsafe knowing the app can be opened without a passcode/ Face ID.

Also the remote unlock is not working. So don’t rely on it to let someone in if you’re away. Recommend getting a different door system

Horrible

Doesn’t auto lock when it’s supposed to. Huge safety issue. Also does not tell you if your door is locked or unlocked.

Great app with some issues

The system does tell you when to change the battery. The product itself has some issues with locking and can be dangerous.
