At first I thought that it was an AI app, and reading more could find why that would be innovative, but no, just a chat app targeting the same phone users and the ones willing to install the app in other phone brands.

Edit: Requiring Google Play login to use this express chat app is pretty stupid in my opinion. Why do apps require Google Play login? Especially a Chinese app? I am on an Android phone with Google play. I am just not signed in to Google play. I installed this app with Aurora store. The app simply throws me back to Play Store which tells me to sign in. Why?

It looks like it's still India-exclusive. I haven't heard much about it online, and with a dedicated chat app I would've expected to if it was a success. Did it bomb?
Problem is, unless you have people willing to jump ship, or technical friends who like to experiment. You're just chatting to yourself

the good old days
And in developing countries, you have to register your phones imei and pay tax if the value of your phone is greater than certain amount. And in that cases the amount of tax is maybe 50% of the actual price of the phone. So your phone is basically a brick with camera. And you get carry a second phone, which is inconvinence. With this I can see the potential use of it. Small, simple and useful wifi hotspot device with actual ability to call like normal phone.
I used to have an Android head unit in my old car, I used my phone hotspot for connectivity
