# UU加速器 vs Sixfast

The clearest difference is monetization model: Sixfast at free with in-app purchases against UU加速器's subscription. UU加速器's advantage is rating (4.8 vs 4.4) and update cadence (weekly vs every 3 weeks). On price, review sentiment, 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 Sixfast sells 19 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

UU加速器 holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: UU加速器 has 1.5K ratings behind it against 220, so its average is the more settled of the two. Written reviews point the same way: 84% of UU加速器's written reviews are positive against 76% of Sixfast's.

UU加速器 ships an update weekly, Sixfast every 3 weeks. The most recent releases landed on September 22, 2026 and September 25, 2026 respectively.
