# FastMath vs SpinxMaker

FastMath and SpinxMaker 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. FastMath sells 5 in-app purchases, starting at $4.99 per 7 days and SpinxMaker sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

FastMath ships an update every 5 days, SpinxMaker every 3 days. The most recent releases landed on September 30, 2026 and September 15, 2026 respectively.
