The August Home Smart Lock doesn't only help you when you lose your keys or prefer not to fumble for them. You can grant access to family members, friends, employees and whoever else is in your circle, and keep track of who enters through the August app.

Here's exactly how it works: The smart lock attaches to your existing deadbolt on the inside of the door and can be installed in under 10 minutes, according to Amazon's product description. Next, download the August app, and when you want to get into your home, the app will automatically unlock the door as you arrive—no button-pressing required. You can then set up Auto Lock if you'd like the door to re-lock behind you after entering.

If you have a little bit of anxiety about remembering whether you locked the door or not, this can also help with that. The smart lock has a sensor that will tell if you if it's securely closed or been left opened.

And a little pro-tip: If you'd like to use the app remotely or through Alexa, you'll also want to get the August WiFi Connect Bridge ($68.05 on Amazon).

One Amazon reviewer wrote, "Absolutely love the lock. Friends love it too and several have purchased one after accessing my house via the app. Love the lock and the general features. I travel a lot for work, so the ability to provide access and the notification when used, limiting the hours and days, has been wonderful."

"Having lived with it for a while now, I can say it works great. The door auto-locks after a pre-set time and sends you a notification. I get LOTS of those telling me indeed the kids don't lock the back door when they tumble out to school and it has auto locked," wrote another.
