Verdict
The clearest difference is rating: 解方程计算器 at 3.9 against 变声吧's 2.5. 解方程计算器 also leads on ads (none vs shown) and review sentiment (17% vs 0%). 变声吧's advantage is update cadence (every 4 weeks vs every 3 months) and iOS requirement (9.0 vs 11.0). On price, in-app purchases and device support there is nothing between them.
