Verdict
The clearest difference is in-app purchases: Boyoyon Sim. at none against FaceClock Calendar's 2. Boyoyon Sim. also leads on update cadence (every 3 weeks vs every 3 months) and iOS requirement (18.6 vs 26.0). FaceClock Calendar's advantage is ads (none vs shown). On price and device support there is nothing between them.
