# Yandex Direct vs O

The clearest difference is review sentiment: O at 100% against Yandex Direct's 48%. O also leads on update cadence (every 6 days vs every 3 weeks). Yandex Direct's advantage is rating (4.6 vs 3.7) and ratings volume (194 vs 7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Yandex Direct holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Yandex Direct has 194 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 48% of Yandex Direct's written reviews are positive against 100% of O's, so the app with the better star average is not the one people write more warmly about.

Yandex Direct ships an update every 3 weeks, O every 6 days. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
