The accompanying app is intuitive and easy to use, providing quick and easy access to features like auto-lock, which can be a life saver. Yes, the August Smart Lock Pro is one of the priciest smart lock kits on the market, but we can confidently say it’s one of the best.

The lock will let you see who has come and gone from your property and at what time, whether they use a key or a PIN. It’s therefore a good option for those who rent out their home on sites like Airbnb.
The Sense is easy on the eyes, so you won’t have to sacrifice the nice look of your home for the beefed-up security. Schlage’s accompanying app is a breeze to use and there’s also a physical override for emergencies, something which is conspicuously absent from many top-contenders in the marketplace.
