# IUV vs 爱主题

The clearest difference is review sentiment: 爱主题 at 50% against IUV's 0%. 爱主题 also leads on rating (4.9 vs 3.5) and ratings volume (15 vs 2). IUV's advantage is ads (none vs shown) and update cadence (weekly vs every 2 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. IUV sells 3 in-app purchases, starting at $1.99 per month and 爱主题 sells 10 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

爱主题 holds the better App Store score, 4.9 against 3.5. That said, the two scores are not equally well evidenced: 爱主题 has 15 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 0% of IUV's written reviews are positive against 50% of 爱主题's.

IUV ships an update weekly, 爱主题 every 2 weeks. The most recent releases landed on July 7, 2026 and September 2, 2026 respectively.
