Simple smartphone app

I am looking for an established smartphone developer with products currently available for iPhone and Android. I have a concept for a very simple app that I think will be popular. It could be ad supported with an option to remove ads. It is very simple and a sharp developer could probably have a beta working in a day or less. Ad supported, it could provide a constant revenue stream. I want a portion of that revenue stream. The deliverables include the executable app and all source code for both IOS and Android, well commented. The app is intended to assist people playing the popular game 'Wordle" from the New York Times web site. It is not intended to find words for the player but helps the player find words that fit. The app will not contain a dictionary. It is simply a visual tool to help find thew word that fits the conditions. If you are not familiar with Wordle, please learn how to play to better understand this app. The app working title is 'No Cheating!' The app will present five vertical scrolling columns (scrolled up and down by swiping) of the upper-case letters A-Z. The scrolling will wrap around, going from Z to ABC again. Across the middle of the scrolling columns is a frame one character high to enclose the current selection of five characters. Each of the letters within the frame has a contextual menu associated with it. The other characters not in the frame do not. The contextual menu for a letter can be called up by a double-tap or, perhaps, by holding down on the leter. I'm open to suggestion, if you have a better idea. The contextual menu has three choices: 'Not Used' - If selected, this menu item will remove this character (A-Z) from all remaining scrolling lists. (not from a locked column.) 'Used Elsewhere' - this menu item will change the background color of the particular letter to orange in EVERY non-locked column. 'Used Here' - This item, when selected, will change the character's background color to green IN THIS COLUMN ONLY and lock the column from further scrolling or deleting characters. When a contextual menu is shown and the user taps outside the menu, this serves as 'cancel' and removes the contextual menu. I would suggest that the first menu item have the default (white) background color, the second item have the orange color and the third menu be green for its background. NOTE: there will be cases where a letter that is green in one (locked) column may be orange in another. Optional: Themes to allow a dark theme for those who prefer. Allow users to select their own 'Used Elsewhere' and 'Used Here' colors.
