# SlabMath vs Grade Sync Pro

The clearest difference is ads: Grade Sync Pro at none against SlabMath's shown. SlabMath's advantage is iOS requirement (14.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. SlabMath sells 3 in-app purchases, starting at $4.99 per month and Grade Sync Pro sells 1 in-app purchase, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.
