TIL #Catima is apparently mirrored onto #RuStore through #Aptoide, or so someone reported: https://github.com/CatimaLoyalty/Android/discussions/1812#discussioncomment-11740997

Few problems with that: I have no control over the RuStore listing, nor do I control the Aptoide listing. Both may very well be malware.

It should go without saying: don't download apps from sketchy unofficial "app stores" and other APK download sites.

https://catima.app/ and https://github.com/CatimaLoyalty/Android link you to all the safe and supported download sources :)
