TTLock

The app generally works okay, but there are some design issues that make its operation unnecessarily cumbersome. My main complaint is that when you add a new user/access code through the app, you have to also PHYSICALLY enter this same code once into the lock itself within 24 hours to "activate" it, or else it'll expire, which severely complicates remote access management. The app claims it's for "security reasons," but I don't see ANY extra security benefit here, just a useless limitation.

I've used this app for two locks for about 3 years. Although slow and poor security, it has been fairly reliable. Recently it has been failing to connect to both of my locks via the internet and via Bluetooth. I get the impression it is not well maintained. There are several frustrating things about the user interface, but isn't too bad. It doesn't handle the locks being in one time zone, while I'm travelling in another time zone very well. It isn't the locks with the problem.

Fixed known issues & created new issues! Since the recent upgrade the entire panel is no longer lit nor active. The battery level is at 70% and the only option is to use the hard key 🔑 to lock and unlock the door. Worked as expected for less than a year. No customer support found.
