# Контур.Диадок vs 1С

The clearest difference is rating: 1С at 5.0 against Контур.Диадок's 4.5. 1С also leads on iOS requirement (13.0 vs 16.0). Контур.Диадок's advantage is review sentiment (55% vs 30%) and ratings volume (35 vs 1). 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.

1С holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Контур.Диадок has 35 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 55% of Контур.Диадок's written reviews are positive against 30% of 1С's, so the app with the better star average is not the one people write more warmly about.

Контур.Диадок ships an update every 3 weeks, 1С every 2 months. The most recent releases landed on September 26, 2026 and September 27, 2026 respectively.
