Verdict

The call

The clearest difference is in-app purchases: PlayClock3D at none against Nanzoo Clock's 1. PlayClock3D also leads on device support and iOS requirement (11.0 vs 13.0). Nanzoo Clock's advantage is review sentiment (100% vs 74%) and update cadence (every 10 days vs monthly). On price there is nothing between them.
