5 stars: everything works well including bonus program.
4 stars: Need to add different document types when registering. Currently only accepts Russian passport, birth certificate, military document. The site version accepts other documents like foreign passport and resident permit, so it is clearly an issue with the app
5 stars: Nice app. But, like your website, it seems that not all part of this app are translated into English. Some parts like train names etc are still in Cyrilic writing. It would be nice if you translate it into English/Latin scripts
3 stars: The app is good, though it still can't see the passengers you have entered on the official site which is ridiculous. I guess, the passengers list is stored locally - the 80th level of security from RZD ;)
5 stars: Very convenient app. The names of the places in english is just teribbly wrong sometimes. These are the examples I noticed. (In brackets is how I found it on the app): Nizhny Bestyakh (Nizhniy Bestiakh) Khabarovsk (HABAROVSK) Yakutsk (Iakutsk) These spellings are how I usually find it on maps. It could also help if, for example \
3 stars: First time login is bugged. App kept saying that data was entered incorrectly when agreeing to terms and conditions despite checking all the boxes. After logging in through website once the app works ok
5 stars: Great app, very useful for traveling by train with no extra fees Some issues with Google pay and Samsung pay, you probably want to look into...
