Updates to smart phone app Herbal-Pro (Apple and Google)

I have an app called Herbal-Pro, which requires some minor updates. More details about the background of the app are available in the attached document "Herbal-Pro app background". I'm wanting the branding (icon, splash screen, menu icons) changed and changes to the content and structure of the information screen. All the image assets in various sizes have already been produced ready for Xcode. The updates for the menu icons and the information screen have already been developed in another draft version of the code which can be used to update the current app. The attached document "Herbal-Pro app update - package 1" provides more specific details of the updates required with some screenshot examples etc. The images and additional documentation with specific content etc will be provided once the job is allocated. The app is developed for Apple and Google. Set up - The current app was built using Cordova on the ionic framework with an SQLite database - There is a technical manual which covers how to set up the development environment and how to maintain the database. - The code for the app can be made available in BitBucket - Apple and Google developer accounts have been established for the management of the smart phone app. Details can be provided on request. If the update is successful, there is additional work available for this app.
