We have an app, https://okbutton.app, built for iOS and now want to develop an Android version to support Google users. The app uses an API to connect to a Firebase database to manage user accounts. The iOS app is already fully developed and live in the Apple App Store, with multiple users already using the app daily. We have a full GIT repo of the current iOS app and plenty of design material that explains the app process. You must work with and read the iOS app, as we have little documentation for the actual code. We're looking for an estimate too on the time and cost. We would also like to make a few minor changes to the iOS app if the budget allows.
