I love my Halo Wi-Fi Enabled Smart lock! My favorite feature is that I do not have to remember keys when going out to my studio in my backyard, and if my kids or husband need something inside while I am gone, I can grant them access with the app. I have an iPhone 12 and had no issues getting the app to work. 

One drawback is having to remember to keep plenty of AA batteries on hand, but I do think it's worth the convenience. The lock looks very nice, works well and so far I love it!
