# Kontur.Talk vs МТС Optimus

The clearest difference is rating: Kontur.Talk at 4.4 against МТС Optimus's 1.0. Kontur.Talk also leads on ratings volume (36 vs 4). МТС Optimus's advantage is monetization model (free vs freemium) and iOS requirement (13.0 vs 16.6). On price, review sentiment, update cadence and ads there is nothing between them.

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

Kontur.Talk holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: Kontur.Talk has 36 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 73% of Kontur.Talk's written reviews are positive against 74% of МТС Optimus's, so the app with the better star average is not the one people write more warmly about.

Kontur.Talk ships an update weekly, МТС Optimus fortnightly. Both last shipped on October 30, 2026.
