# AT vs GGUZUNI

The clearest difference is ads: AT at none against GGUZUNI's shown. AT also leads on update cadence (every 2 weeks vs every 3 months) and ratings volume (394 vs 16). GGUZUNI's advantage is review sentiment (97% vs 77%). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. AT sells 10 one-off in-app purchases and GGUZUNI sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for AT against 4.6 for GGUZUNI. That said, the two scores are not equally well evidenced: AT has 394 ratings behind it against 16, so its average is the more settled of the two. Written reviews are what separate them: 77% of AT's written reviews are positive against 97% of GGUZUNI's.

AT ships an update every 2 weeks, GGUZUNI every 3 months. The most recent releases landed on October 19, 2026 and October 21, 2026 respectively.
