Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Ultraloq U-Bolt Pro WiFi comes out ahead by a clear margin (3.8 vs 4.3). The gap is mostly about Users needing maximum unlock options like fingerprint scanning without a bridge — read the strengths below before deciding.

Ranked #4 in Best Smart Locks

Level Lock+

3.8

$349as of Apr 22

The Level Lock+ is widely considered the best smart lock for Apple users due to its seamless HomeKit integration, Home Key support, and discreet design that hides the motor inside the door. However, it requires a separate Wi-Fi bridge for remote control and currently has limited compatibility with non-Apple ecosystems like Google Assistant. While installation is straightforward, the included security cylinder is a weak point that may require upgrading by a locksmith 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

4.3

$199as of Apr 22

The Ultraloq U-Bolt Pro Wi-Fi offers exceptional versatility with six unlock methods and built-in Wi-Fi, making it a top choice for keyless entry. However, its utility is slightly hampered by the lack of Apple HomeKit support, reliance on 2.4GHz Wi-Fi, and mediocre battery performance. Despite these limitations, its compact design and robust fingerprint sensor make it a strong asset for 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.
