Why to put front and center that chat app? I mean, is not something that makes it unique, if the app itself can run in android and iOS then it is just a chat app, with far less users than i.e. whatsapp.
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.
