# OnClock vs Necrophonic Pro

The clearest difference is price: OnClock at $0.99 against Necrophonic Pro's $9.99. Necrophonic Pro's advantage is rating (3.0 vs 2.5) and update cadence (every 5 days vs every 3 weeks). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.

Necrophonic Pro holds the better App Store score, 3.0 against 2.5. Both are backed by a comparable volume of ratings — 2 and 1 respectively. Written reviews complicate that: 63% of OnClock's written reviews are positive against 60% of Necrophonic Pro's, so the app with the better star average is not the one people write more warmly about.
