List App Development with Ionic Framework or similar

I would like to develop a list app that in inspired by the Apple iOS "Reminders" app ([login to view URL]) but serves a more specific purpose. Having it built with Ionic Framework or similar would be most suitable as I intend to publish this cross-platform. There will essentially be 4 main screens in the app: 1. Index of lists 2. Individual list showing items in that list 3. Settings Screen with 3 settings 4. Static "About" screen Additionally, there will be some pop-overs: 1. Pop-over for individual list settings 2. Pop-over for choosing a list into which an item can be moved The app will need to save user data using localStorage. I will provide wireframes showing all screen requirements. I will need to be given the source code when you are done. I will then publish the app myself. Therefore, I do not need you to create an app icon or app splash screen. I do not need you to publish it and I do not need you to submit it to any app stores. I intend to publish this myself to iOS, Android and Windows devices. I would therefore need this to be kept in mind when developing. I will add styling myself after handover. Therefore, a standard "Material" theme styling is all that is needed. Thank you.
