Verdict
The clearest difference is ads: KCalc Lock at none against 应用软件锁's shown. KCalc Lock also leads on monetization model (free vs free with in-app purchases) and update cadence (every 3 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
