Verdict
The clearest difference is in-app purchases: CalcificAID at none against Clinical Tree's 10. CalcificAID also leads on review sentiment (100% vs 80%). Clinical Tree's advantage is ads (none vs shown) and update cadence (monthly vs every 37 months). On price, rating, ratings volume and device support there is nothing between them.
