# 悠悠 vs Oxygen

The clearest difference is ads: Oxygen at none against 悠悠's shown. 悠悠's advantage is update cadence (weekly vs every 4 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 悠悠 sells 10 one-off in-app purchases and Oxygen sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

悠悠 ships an update weekly, Oxygen every 4 weeks. The most recent releases landed on September 30, 2026 and October 11, 2026 respectively.
