About this app

With Bold, your smartphone is your key. Enter and leave your house with your phone in your pocket; Bold will (auto) unlock and lock your door as you come and go.

Having guests over? Share virtual keys with whomever, whenever. Invite people with the Bold app and activate or deactivate their virtual key. You are the digital key master: give your spouse permanent access, let the plumber in Monday morning and the cleaning lady every Friday afternoon. You decide!

With the highest level of security (think of digital banking-security), your house is safer than ever before. By just replacing the cylinder, burglars will be unable to enter your house using the common techniques.

Bold's simple and elegant design makes your front door look better, your house safer and your life easier.

Why did you change it? This review is for the app, not the product which is great, I want to make that perfectly clear. So two issues here... 1. having to login again when you want to get through your door because the app has failed 2. Why on earth have you used black text boxes on a black background. When you are outside trying to reload your app and enter in SMS codes YOU CANNOT SEE THEM!! I used another entrance with a key. Poor update.

I have 3 locks, 2 bold connect as controller of which one should be gateway for one lock and another bold connect for 2 other locks. The gateways never work well, the only thing that works is Bluetooth. Gateways show as disconnected from the network in the app but as connected on the router, very inconsistent ... I'm very annoyed with this.

Opening the door is really really slow, sometimes lets me stand in front of the door for about 40 to 60 seconds or longer, even had to reboot the device. (Pixel 7 pro). Also get an error on a regular basis. A key is a lot faster and much more trustworthy. Had no issues with my previous iphone 12. Don't recommend getting this if you have a pixel 7 pro (did not test other Android devices so far). Really really really frustrating...... :(
