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.

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

Was good and groundbreaking a few years ago but can use an UWB upgrade. Too many times I am right I front of my door and Bold does not open.
