I need a mobile app (a big data project) for ios and android platforms

I want an app that will work simultaneously with ios and android. general features of the application - will be a membership system, members will send and send a document photo at the entrance. (In the admin panel, members' control will be checked manually and their membership will be confirmed) - when members enter the system, they will be able to see their special events and opportunities. - the banners that we entered in our system from time to time will be shown to the people and the statistics of it will be kept - there will be a section in the system where you can watch videos or advertisements, and we will upload the ads to be viewed here. (we won't use google ads). Members will earn points from each ad they watch and spend on these points in the shopping section. In addition, the system will create a coupon or QR code for the places where they receive a discount, and thus they will benefit from the discounts from the stores where they go. - A practical coupon or code verification system is required for the stores. - In the admin panel, there must be places such as adding events, adding opportunities, adding videos, adding products to the store. - Interface design (UI) can be done by the different user for extra paid - the app must be work in the two platforms same time - i want to send the push message to all users about their areas of interest or their profile - I will send the detailed project after the real offers. Plese give me the real price offers. - I would like to use the member records in the database in the member entries of my other projects. So I want an api that will put an api and other web sites in front of the recording sections. (such as being a member of another application with facebook membership information) Similar Apps [login to view URL] [login to view URL] [login to view URL] [login to view URL]
