Verdict
The clearest difference is rating: COLON at 5.0 against SClock's 4.3. COLON also leads on review sentiment (88% vs 50%) and in-app purchases (none vs 1). SClock's advantage is update cadence (fortnightly vs every 29 months) and ratings volume (24 vs 1). On price, device support and iOS requirement there is nothing between them.
