Such social media apps are extremely hard to overtake due to the critical mass effect, and that's the reason why Facebook still stands after all this time. Even sites that are strictly better than Facebook often fail due to not having enough users, let alone those that are worse. Unless there's a very strong incentive for users to use byte over TikTok, there's no way it will survive.

The official launch is the one time a bunch of people may give you the benefit of the doubt and try your app, and if you fall so short on the first impression, most people will probably never give it another try. And again, without users, there's no content, and without content, there's no users.
