Verdict
The clearest difference is in-app purchases: ダクトサイズ計算Pro at none against Elbow Calculator's 1. ダクトサイズ計算Pro also leads on update cadence (every 2 days vs every 5 months). Elbow Calculator's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.1). On price and device support there is nothing between them.
