Mobil app , ( have the app and it works just fine , need to rewrite the source code )

We have an existing Mobil app which we don't have the source code for it and need to rewrite the code so we can improve it to phase 2 -This app is both android base and apple base -user downloads and registers and gets approved by admin , new user get a notification of approval and can get in the app . - Admin can remove member , add members, or disconnect them or send them push notification. -once approved and logged in , can search for lyric by title or part of the lyric, music assigned number , by author or music composer . Play the music alone( connect to site or download music) or click to see the Lyric also , - Pages with lyric have icons of choice to play the music, add to favorite, share it , and some more of standard features -Need nice graphics , easy to edit & work with , upload and download - Admin is fully featured to add musics ,lyrics .
