Verdict
The clearest difference is ads: SenSaaS! AP at none against HC Key's shown. SenSaaS! AP also leads on monetization model (free vs ad-supported) and update cadence (every 2 months vs every 5 months). HC Key's advantage is review sentiment (100% vs 67%) and iOS requirement (13.4 vs 15.0). On price, in-app purchases and device support there is nothing between them.
