Verdict
The clearest difference is update cadence: Nanzoo Clock at every 10 days against Clockwiser's every 2 months. Nanzoo Clock also leads on iOS requirement (13.0 vs 15.1). Clockwiser's advantage is monetization model (free vs free with in-app purchases) and device support. On price and in-app purchases there is nothing between them.
