# NN Clock vs Premium Clock Collection

The clearest difference is rating: Premium Clock Collection at 4.6 against NN Clock's 3.8. NN Clock's advantage is review sentiment (77% vs 38%) and in-app purchases (none vs 8). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. Premium Clock Collection sells 8 one-off in-app purchases. NN Clock asks for nothing beyond the download.

Premium Clock Collection holds the better App Store score, 4.6 against 3.8. Both are backed by a comparable volume of ratings — 36 and 56 respectively. Written reviews complicate that: 77% of NN Clock's written reviews are positive against 38% of Premium Clock Collection's, so the app with the better star average is not the one people write more warmly about.
