Android to iOS Medical App Conversion

I'm seeking a proficient developer to convert my existing Android medical app into an iOS version. The core functionalities of the app include:

- Appointment scheduling
- Symptom checker
- Medication reminders

Ideally, you should have prior experience in converting Android apps to iOS and a good understanding of both platforms exhibiting fluency in app development for them. Understanding medical applications would be a plus.

Once completed, we can discuss extending the scope of work for future developments. I can provide the built APK for reference. Please confirm your expertise in these areas and your approach to the task when bidding.
