There is one app which is exclusively present in the Jio Store on Jio Phone, but not on other phones.
It is the NM app (NM=Narendra Modi).
The official Narendra Modi app on Android play store has 5-10 mn downloads, but as you know, Jio Phone runs on KaiOS and the phone doesn’t allow third party apps yet.
That is, Jio decides which apps to allow and which ones to not (FYI: Jio Phone officially doesn’t support WhatsApp yet).
Apart from Facebook, the first non-Jio app is the NM app.
Interesting, no?
