# 复利计算机 vs 婴儿翻译器

The clearest difference is update cadence: 婴儿翻译器 at every 5 days against 复利计算机's every 2 months. 婴儿翻译器 also leads on iOS requirement (12.0 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 复利计算机 sells 1 one-off in-app purchase and 婴儿翻译器 sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

复利计算机 ships an update every 2 months, 婴儿翻译器 every 5 days. Both last shipped on October 24, 2026.
