# Chart AI vs Quantify.US

The clearest difference is ads: Quantify.US at none against Chart AI's shown. Chart AI's advantage is ratings volume (38 vs 1) and update cadence (weekly vs every 3 weeks). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Chart AI sells 2 in-app purchases, starting at $8.99 per 7 days and Quantify.US sells 7 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Quantify.US holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Chart AI has 38 ratings behind it against 1, so its average is the more settled of the two.

Chart AI ships an update weekly, Quantify.US every 3 weeks. The most recent releases landed on November 8, 2026 and November 5, 2026 respectively.
