# 解方程计算器 vs Calculator

The clearest difference is review sentiment: Calculator at 70% against 解方程计算器's 17%. Calculator also leads on rating (4.6 vs 3.9) and ratings volume (203 vs 14). 解方程计算器's advantage is ads (none vs shown) and iOS requirement (11.0 vs 15.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. 解方程计算器 sells 4 one-off in-app purchases and Calculator sells 4 in-app purchases, starting at $2.49 per month. Whichever you choose, the download price is not the number that matters.

Calculator holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Calculator has 203 ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 17% of 解方程计算器's written reviews are positive against 70% of Calculator's.

解方程计算器 ships an update every 3 months, Calculator every 2 months. The most recent releases landed on October 1, 2026 and October 20, 2026 respectively.
