Rotor101riot/PhoneTransfer — reverse-engineered prompt

Build me a desktop app called PhoneTransfer that lets people move their own phone data between Android and iPhone in any direction, Android to Android, Android to iPhone, iPhone to Android, and iPhone to iPhone. It should run entirely on the user’s computer, with no cloud, no account, no telemetry, and no outside service handling the data.

I want it to automatically detect connected devices, let me choose the source and destination, pick which categories to transfer, and then run the transfer. Support the main stuff people care about, like contacts, texts, call history, photos, videos, notes, calendar, reminders, bookmarks, wallpaper, and voicemail where possible. If something is not supported for a certain phone pair, make that obvious in the UI instead of failing later.

Please include a dry run mode, clear progress updates, and detailed logs saved locally. Also show friendly warnings for known limitations and for the more experimental iPhone backup and restore flow. Make the app practical to run on a normal Windows machine first, and look up current docs online if you need to.
