# CMY vs DeckKeeper

The clearest difference is ads: CMY at none against DeckKeeper's shown. DeckKeeper's advantage is update cadence (every 3 weeks vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. CMY sells 2 one-off in-app purchases and DeckKeeper sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

CMY ships an update every 2 months, DeckKeeper every 3 weeks. The most recent releases landed on November 1, 2026 and November 7, 2026 respectively.
