Creation of a mobile application (IOS and android)

I am looking for a freelance to design a mobile application compatible with IOS and Android

The need mainly concerns the addition and geolocation of different places according to a specific category (details of the place / filter / modification, also access to the backlog). The main pages of the application will be communicated and reviewed more precisely with the developer.

Have a well secured application, RGPD, database security.
