Level Bolt
Score: 85/100
Ultraloq Bolt
Score: 92/100Rankings

The ULTRALOQ Bolt Fingerprint WiFi Smart Deadbolt offers robust ANSI Grade 1 security with seamless native Apple Home integration. It features built-in WiFi and Thread support, eliminating the need for a separate hub for remote access. The main trade-off is the lack of a Micro-USB backup port and reliance on 2.4GHz WiFi.

The Level Bolt is a retrofit smart lock that installs inside an existing deadbolt, preserving the original hardware and aesthetic appearance of the door. It offers multiple access methods and high security standards but suffers from short battery life and the need for additional hubs. It is best suited for design-conscious homeowners who want smart technology without visible hardware changes.
