# 计算器 vs 真好算

The clearest difference is ads: 真好算 at none against 计算器's shown. 真好算 also leads on review sentiment (67% vs 35%) and monetization model (free vs free with in-app purchases). 计算器's advantage is ratings volume (826 vs 3) and iOS requirement (15.6 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 计算器 sells 2 one-off in-app purchases and 真好算 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

真好算 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 计算器 has 826 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 35% of 计算器's written reviews are positive against 67% of 真好算's.

计算器 ships an update every 2 months, 真好算 monthly. The most recent releases landed on September 21, 2026 and September 23, 2026 respectively.
