The call

The clearest difference is price: Allister at Free against ClockZ Pro's $9.99. Allister also leads on rating (5.0 vs 4.2) and review sentiment (91% vs 56%). ClockZ Pro's advantage is ratings volume (88 vs 1) and iOS requirement (9.0 vs 26.0). On ads, in-app purchases, monetization model and device support there is nothing between them.
