Verdict
The clearest difference is ads: Construction Boarding at none against SimpleVenti's shown. Construction Boarding also leads on update cadence (every 2 weeks vs every 5 weeks). SimpleVenti's advantage is iOS requirement (12.0 vs 14.0). On price, in-app purchases and device support there is nothing between them.
