I am going to make a native android app very similar to Happie:
[url removed, login to view]
My app does not need to be multilingual but need to replicate all other functionalities of Happie, like submitting image and text jokes, commenting, rating, flagging, user profile and unlimited scrolling, as well as inline and splash advertising. The design and page structure need to be same as Happie.
The login will be through google OAuth2. The app should have firebase push notification. I will provide the backend api for the data. The app need not to work offline.
Please study the app and give me a quote if you are interested to make it.
Also if possible please provide the links to similar apps that you've developed before.
