# 数字钥匙 vs AOD Smart

The clearest difference is review sentiment: AOD Smart at 100% against 数字钥匙's 50%. AOD Smart also leads on iOS requirement (11.0 vs 13.0). 数字钥匙's advantage is rating (5.0 vs 4.0) and update cadence (monthly vs every 3 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

数字钥匙 holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 1 and 1 respectively. Written reviews complicate that: 50% of 数字钥匙's written reviews are positive against 100% of AOD Smart's, so the app with the better star average is not the one people write more warmly about.

数字钥匙 ships an update monthly, AOD Smart every 3 months. Both last shipped on November 3, 2026.
