# 火球选股 vs 纳米AI

The clearest difference is review sentiment: 火球选股 at 100% against 纳米AI's 54%. 火球选股 also leads on monetization model (free vs free with in-app purchases) and iOS requirement (9.0 vs 15.0). 纳米AI's advantage is rating (4.3 vs 1.0) and ratings volume (211 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 火球选股 sells 9 one-off in-app purchases and 纳米AI sells 10 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

纳米AI holds the better App Store score, 4.3 against 1.0. That said, the two scores are not equally well evidenced: 纳米AI has 211 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of 火球选股's written reviews are positive against 54% of 纳米AI's, so the app with the better star average is not the one people write more warmly about.

火球选股 ships an update every 4 weeks, 纳米AI weekly. The most recent releases landed on November 2, 2026 and November 4, 2026 respectively.
