Hi there,
I read your post that you want to clone tiktok app. This is the most favourite app in the market now. And it has many features like chat, video editing, comments, friends etc. We will list all the features and start the work by modules.
I can provide you estimate based on the features you want from the app or we can go in a dedicated model. So let's get connected and discuss the things in details. I have done many projects in mobile app and can handle all the things like iOS, Android, Design and backend of the app.
So I hope I will get a positive response from you.
Thanks.
