# 纳米AI vs 计算器i

The clearest difference is ads: 纳米AI at none against 计算器i's shown. 纳米AI also leads on ratings volume (211 vs 10). 计算器i's advantage is review sentiment (76% vs 54%) and rating (4.5 vs 4.3). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 纳米AI sells 10 in-app purchases, starting at $6.99 per month and 计算器i sells 6 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

计算器i holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: 纳米AI has 211 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 54% of 纳米AI's written reviews are positive against 76% of 计算器i's.
