Ranked #3 in Best Smart Locks

Level Lock+

4.3

2 sources$345.99as of Aug 1

Apple users widely consider the Level Lock+ the best smart lock available, thanks to tight HomeKit integration, Home Key support, and a discreet design that hides the motor inside the door. Remote control requires a separate Wi-Fi bridge, and compatibility with non-Apple ecosystems like Google Assistant is limited for now. Installation is straightforward, but the included security cylinder is a weak point that may need a locksmith to upgrade for maximum protection.

Strengths

— Understated industrial design that hides the smart mechanism inside the door frame
— Supremely easy to install and set up using only a Phillips screwdriver
— Supports Apple Home Key for instant NFC unlock via iPhone or Apple Watch

Watch-outs

— Limited to local operation without purchasing a separate Bluetooth-to-Wi-Fi bridge for remote access
— Essentially incompatible with Google Assistant until the Thread radio is activated
— Security cylinder lacks security pins and can be picked with a simple bump key

Higher ratedRanked #2 in Best Smart Locks

Ultraloq U-Bolt Pro WiFi

4.4

3 sources$159.99as of Aug 1

Six unlock methods and built-in Wi-Fi make the Ultraloq U-Bolt Pro Wi-Fi one of the more capable keyless entry options around. Working against it: no Apple HomeKit support, a 2.4GHz-only Wi-Fi radio, and mediocre battery performance. The compact design and reliable fingerprint sensor still make it a strong addition to most smart homes.

Strengths

— Supports six unlock methods including fingerprint, keypad, key, app, geofence, and Bluetooth
— Built-in Wi-Fi connectivity eliminates the need for a separate bridge or hub
— Compact design fits standard doors with universal backset adjustment (2-3/8" or 2-3/4")

Watch-outs

— Requires 2.4GHz Wi-Fi only and does not support dual-band networks
— Battery life is described as so-so, requiring 4 AA batteries
— Lacks support for Apple HomeKit and Amazon Key integration

How they stack up

Level Lock+

The Level Lock+ offers a uniquely discreet design that hides the motor inside the door, a feature absent in the bulky Schlage Encode Plus and August Wi-Fi Smart Lock, and provides superior Apple Home Key integration. However, it is significantly less versatile than the Ultraloq U-Bolt Pro, which supports six unlock methods including fingerprint, whereas the Level Lock+ requires a separate bridge for remote access and has limited Google Assistant compatibility.

Ultraloq U-Bolt Pro WiFi

The Ultraloq U-Bolt Pro WiFi offers the most unlock versatility with six methods, including a robust fingerprint reader that the Schlage Encode Plus and August Wi-Fi Smart Lock completely lack. While it shares the 2.4GHz Wi-Fi limitation with the August, it avoids the Level Lock+'s need for a separate bridge for remote control, though it sacrifices Apple HomeKit support which is a primary selling point for the Level Lock+ and Schlage.
