# LuckyCat vs 3s Kakeibo

The clearest difference is ads: LuckyCat at none against 3s Kakeibo's shown. 3s Kakeibo's advantage is update cadence (every 3 days vs every 10 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. LuckyCat sells 7 in-app purchases, starting at $0.99 per 7 days and 3s Kakeibo sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

LuckyCat ships an update every 10 days, 3s Kakeibo every 3 days. The most recent releases landed on October 20, 2026 and October 24, 2026 respectively.
