# Chinese Calendar vs Google Smart Lock

Chinese Calendar's advantage is iOS requirement (7.0 vs 15.0). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Chinese Calendar sells 1 one-off in-app purchase. Google Smart Lock asks for nothing beyond the download.

Google Smart Lock holds the better App Store score, 2.5 against 2.0.
