# Smart Doorbell vs Qr

The clearest difference is rating: Qr at 4.4 against Smart Doorbell's 2.5. Qr also leads on update cadence (fortnightly vs every 4 months) and ratings volume (3.6K vs 4). Smart Doorbell's advantage is ads (none vs shown) and iOS requirement (8.0 vs 13.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Smart Doorbell sells 4 in-app purchases, starting at $2.99 per month and Qr sells 6 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Qr holds the better App Store score, 4.4 against 2.5. That said, the two scores are not equally well evidenced: Qr has 3.6K ratings behind it against 4, so its average is the more settled of the two.

Smart Doorbell ships an update every 4 months, Qr fortnightly. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
