# UU加速器 vs KrKrCat

The clearest difference is monetization model: KrKrCat at free with in-app purchases against UU加速器's subscription. KrKrCat also leads on update cadence (every 2 days vs weekly) and review sentiment (93% vs 84%). UU加速器's advantage is ratings volume (1.7K vs 9) and iOS requirement (13.0 vs 16.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. UU加速器 sells 11 in-app purchases, starting at $1.99 per month and KrKrCat sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for UU加速器 against 4.9 for KrKrCat. That said, the two scores are not equally well evidenced: UU加速器 has 1.7K ratings behind it against 9, so its average is the more settled of the two. Written reviews are what separate them: 84% of UU加速器's written reviews are positive against 93% of KrKrCat's.

UU加速器 ships an update weekly, KrKrCat every 2 days. Both last shipped on October 24, 2026.
