# ZeroSigma vs SPY 0DTE GEX

ZeroSigma and SPY 0DTE GEX are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support 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. ZeroSigma sells 2 in-app purchases, starting at $79.00 per month and SPY 0DTE GEX sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
