# StockDynamics vs Quantify.US

StockDynamics and Quantify.US are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. StockDynamics sells 13 in-app purchases, starting at $2.99 per month 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.

StockDynamics ships an update fortnightly, Quantify.US every 3 weeks. The most recent releases landed on October 14, 2026 and October 7, 2026 respectively.
