Native UI design for Android and iOS simple app

We have the screen flow and structure of a simple app to receive one-way (incoming only) messages. The designed screens and structure is attached. We need an UI designer who can build the screens for Android and iOS (independently for each platform). The most important thing is that the design for each platform respects the standard and style of each, using native elements and controls. The screens we built are a general example. You can make changes on each screen (not on the flow), add icons, modify colors, change the position of the elements, and all you need to match the native style of each specific platform. * On the “Settings” screen (P7), appropriate icons must be placed. * On the “Message” screen (P4), there’s a list of attachments. We need 2 versions for the same screen: * Compact view: use icons, name and a short description for each attachment type. * Expanded view: each attachment on the list must show a pre-view of the attachment, according to the type. Text and icons can be used if needed. Icons must be placed on actions when possible. The main Color is #0E641A
