It's a marketing campaign by "Rocketbank", nothing to see here
The app is in fact useless - it is restricted access, limited to either the funders of the project or to the clients of (an obscure Russian bank) "Rocketbank". The only other way to get the app to work is through a premium SMS to a Russian-only short number. Too bad the article didn't bother mentioning this - it would have saved me the bother of downloading.
So at least the Android app is at best a pretty dirty marketing campaign targeted purely at the Russian market, and at worst a scam.
Which makes me wonder about the reality of the satellite, too
