Verdict
The clearest difference is ads: KCalc Lock at none against Hidem's shown. KCalc Lock also leads on review sentiment (97% vs 74%) and update cadence (every 5 days vs every 4 weeks). Hidem's advantage is ratings volume (928 vs 45). On price, in-app purchases, monetization model and device support there is nothing between them.
