Verdict
The clearest difference is price: Masterbezel at Free against 投影计算器's $6.99. Masterbezel also leads on update cadence (every 4 days vs every 30 months) and device support (4 vs 2). 投影计算器's advantage is iOS requirement (12.0 vs 15.1). On ads and in-app purchases there is nothing between them.
