I would like to build a money saving circle app for both android and ios, where it allows a user to create a group of friends to save a fixed amount of money monthly and one member gets the sum amount at the end of every month. It also allows payment through the app.
I'm not sure which technology best fits these requirements, whether going completely native or using cross platform technologies, and which database and backend can be used.I need an expert to guide me and tells me how to start and what are the technologies and frameworks do I need.
Thanks
