Build an app on IOS and Android based on existing app on app store(Hong Kong) and the name is "福布斯環球聯盟"(forbes Global Alliance).

I need you to build the exact app which now is still on ios but will add some spaces for advertising space. it should have a backend to update the data and the backend should be hosted somewhere which we an access. pls talk to me and i will give you more detail info. The original source code(for android and for IOS) will be passed to us by previous developers and now they are on our hand but i think we need to verify whether it can be reused. For the beckend, you have to build from scratch for both versions. And, for the first app(Android) it should be done in 4 weeks and for IOS, it should br done in 3 weeks after the android version. For the backend, it should be done in the 6th week. Also, the app is in Chinese so i think the developer/tester should know how to manage/deal with these content. the app is on app store(Hong Kong), and the name is "福布斯環球聯盟"(forbes Global Alliance). pls try to install the app to evaluate the functionalities.

High quality is required for sign off the project. Don't bid a low price and keep asking to increase the cost. I will block you if i find your initial price is too lower than your final price. the source code can be shared by potential freelancers if i think they have the capabilities
