# Saby vs Контур.Диадок

The clearest difference is rating: Saby at 4.7 against Контур.Диадок's 4.5. Saby also leads on ratings volume (188 vs 35). Контур.Диадок's advantage is review sentiment (56% vs 48%). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Saby holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Saby has 188 ratings behind it against 35, so its average is the more settled of the two. Written reviews complicate that: 48% of Saby's written reviews are positive against 56% of Контур.Диадок's, so the app with the better star average is not the one people write more warmly about.

Saby ships an update every 9 days, Контур.Диадок every 2 weeks. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
