Verdict
The clearest difference is update cadence: Calendar Clock Administrator at every 2 weeks against SOSglasses's every 2 months. Calendar Clock Administrator also leads on ratings volume (25 vs 3). SOSglasses's advantage is rating (5.0 vs 4.6) and iOS requirement (11.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
