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.

Garbage. Absolutely unacceptably long load screen time, over 5 minutes on a blank landing screen. We don't need digital locks, another reason to keep using physical keys! FIX THIS HANGING ISSUE NOW YOU HAVE LOCKED ME OUT OF MY BIKE (Bold lock is on the bike bunker provided by the city, the app is the problem).

After opening the app we all first get an "can't communicate with device" error. After clicking it away, the locks work.

I have 2 of locks. The app does the job, usually. Unlocking is rather slow and it often takes more that 1 try. 2 stars for not having a Wear OS integration. If you can do it for Apple Watch, you can do it for Wear OS watches too

Hi Nedyalko, thanks for your review! We are working on Wear OS integration, so stay tuned. A workaround for now (if you have a Bold Connect or Bold Elite) is to connect the Lock to Google Home and use the Google Home app on your watch to control the lock. Best regards, Bold Service Team
