Verdict
The clearest difference is review sentiment: Calculator # at 60% against 解方程计算器's 17%. Calculator # also leads on rating (4.6 vs 3.9) and ratings volume (36K vs 14). 解方程计算器's advantage is ads (none vs shown). On price, update cadence, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Calculator # sells 6 in-app purchases, starting at $1.49 per month and 解方程计算器 sells 4 one-off in-app purchases. 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 36K ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 60% of Calculator #'s written reviews are positive against 17% of 解方程计算器's.
Calculator # ships an update every 2 months, 解方程计算器 every 3 months. The most recent releases landed on October 28, 2026 and October 17, 2026 respectively.
