# CPU vs SealProof

The clearest difference is ads: SealProof at none against CPU's shown. CPU's advantage is iOS requirement (15.6 vs 18.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. CPU sells 1 one-off in-app purchase and SealProof sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CPU ships an update fortnightly, SealProof every 2 weeks. The most recent releases landed on November 3, 2026 and October 24, 2026 respectively.
