I had wanted to write this app for a long time. Strangely enough, in the eight months since Yandex opened the API for Yandex.Subscriptions after Google Reader was shut down, not a single iOS client had appeared. And I wanted such an app for myself as well. I started reading news at home with a cup of tea, then continued on the road on my iPad — everything I had already read was marked as read, beautiful. And in general it is simply more convenient for me to read news on the iPad. Somehow the web version of Subscriptions does not work particularly fast.
In the app you can not only read news and share it on social networks or add it to Safari Reading List, but also manage subscriptions — add new feeds and remove the ones already added.
If there is no app, write it yourself :) The app is free.
