# SlabMath vs Reverse Holo

The clearest difference is ads: Reverse Holo at none against SlabMath's shown. SlabMath's advantage is device support (3 vs 1) and iOS requirement (14.0 vs 16.4). On price and in-app purchases there is nothing between them.

Both are free to download. SlabMath sells 3 in-app purchases, starting at $4.99 per month and Reverse Holo sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
