Verdict

The call

The clearest difference is review sentiment: Nuki Smart Lock at 90% against bOS Client's 29%. Nuki Smart Lock also leads on ratings volume (510 vs 2) and update cadence (every 3 weeks vs every 3 months). bOS Client's advantage is rating (5.0 vs 4.7) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

bOS Client holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Nuki Smart Lock has 510 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 29% of bOS Client's written reviews are positive against 90% of Nuki Smart Lock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

bOS Client ships an update every 3 months, Nuki Smart Lock every 3 weeks. The most recent releases landed on August 16, 2026 and September 24, 2026 respectively.
