There is no longer an easy way to see an estimated MMR of the player, and the app fails Play Store's UX guidelines, and I don't have much resource to fix it all up. So, the app was delisted from Play Store, and you can still install older versions, but there will be no future updates.
This is a WearOS app and watchface for displaying your Dota 2 MMR. On first launch, you will be prompted to input your (or somebody else's) player ID. After that, you will be able to see your estimated MMR every time you look at your watch. When you click on the MMR, detailed view is shown. You can add the MMR complication to the other watchface that supports it as well.
