# 纳米AI vs Calculator H

The clearest difference is review sentiment: Calculator H at 100% against 纳米AI's 54%. Calculator H also leads on rating (4.9 vs 4.3) and monetization model (free vs free with in-app purchases). 纳米AI's advantage is ratings volume (211 vs 28). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 纳米AI sells 14 in-app purchases, starting at $6.99 per month and Calculator H sells 3 in-app purchases, starting at $2.99 per year. Whichever you choose, the download price is not the number that matters.

Calculator H holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: 纳米AI has 211 ratings behind it against 28, 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 100% of Calculator H's.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
