Write an iPhone application and an android application with control panel

I need an iPhone app and an android. I already have a design for it, I just need it to be built. I need a programmer who can deal with ios and android apps with control panel . I want to make app that show bloodline ( family tree ) with names and photos just for males . It will be like expanding system from above ( grands ) to down ( grandsons) so be like zoom in and out through family tree screen. Also when you click on any family member it will show you information about member like name,profile picture, date of birth, nickname , phone number,job and description. It’s similar like this app MyHeritage by [login to view URL] [login to view URL] App additive; App must be private for my family tree no one should download it until you approved by admin . Every member must added by admin in family tree to link his profile with his location in tree - profile for each members: member and admin can edit picture, nickname , job,phone number, date of birth and description, date of birth. As a member you can change all your info except your name just by admin who can change any info in member’s profile . - Chatting : you can record voice, add photos, video like WhatsApp and admin can close chatting , block one member or more. No video call or voice call. - Home page Notifications - Invitation and occasion: in this page 4 lines ( name of Invitation) ( date of Invitation) ( details about Invitation) ( location of Invitation it must be located by GPS) all this details should approved by admin . Also after adding Invitation as a post , all other members can see name of member who post the Invitation and it show up as a notification in other members’ page they can accept or reject the invitation and as a result of this process admin can see member name who accept and reject and other members who didn’t decide. - A member can see notifications, family tree, profile, chatting, invitations and occasion . - Poetry page : it contain 3 lines first line ( name of poet ) second line ( story of poetry ) third line ( the poetry ) . Any member can share on this page without admin permission . - Documents page ; it contains 3 lines : ( name ) ( notes ) ( upload files and pictures : every member can take live picture and upload it )without permission from admin. - Photo ( memories) page ; in this page you can see (new memory) icon lead you to new page which contain 3 lines ( name of memory) ( date of memory) ( upload pictures and video icon) . And every post from members should approved by admin before posting. - Charity page ; just admin can edit this page . It contain ( name of Charity) ( founder of Charity) ( deputy of founder) ( advisor) ( ؟؟؟؟) (Members) (FAQ) . Also every member can see (Total amount of donors ) ( Amount to be paid) . Note ; the members can’t see other amount to be paid of other members. Also in this page admin can edit all info in it . - Voting system ( should be by time ) ; every member can add voting depending on info that added and other members can vote. Voting result doesn’t show unless time ending . note: i want for android : java for iPhone: swift backend and admin panel: php
