August Wi-Fi Smart Lock in silver

Quick verdict

The August retrofit design is its killer feature. Snap it over your existing deadbolt, keep your keys, no locksmith needed. It works with basically every voice assistant. The tradeoff is heavy cloud dependency, so local-first buyers should look elsewhere.

Standout: Retrofit design installs over your existing deadbolt in minutes with no locksmith needed.
